It encapsulates the functionality required for objects that orchestrate time lines. It has one notorious child: Clock . All the handlers defined on AbstractClock do nothing. They become meaningfull in some of its descendants. The documentation of this object just explains what these handlers mean. See Also Clock and its knownChildren .

In fact, every SK8 object you see on the Stage is a descendant of Actor. The actor's geometry is defined by three masks (or regions): the boundsRegion , the fillRegion and the frameRegion . The boundsRegion is the space the whole actor takes. The frameRegion is the perimeter of the bounds. Its size is specified by the frameSize property. The frameRegion can be empty (when the framesize = {0,0} ). The fillRegion is the space inside the frame, or more generally, the difference between the bounds and the frame. Each actor has three handlers which compute these masks: makeBoundsRegion , makeFillRegion and makeFrameRegion . If you want the implement a new geometry, these handlers will have to be redefined. Most of SK8 users, however, will never need to do this. The actor's size and location are manipulated using the boundsRect property. The boundsRect specifies a rectangle within which the actor's bounds will be inscribed. The boundsRect is represented as a list of 4 numbers of the form {left, top, right, bottom} . The actor's masks are also used for drawing. The frameRegion is rendered with the actor's frameColor. The fillRegion is rendered with the actor's fillColor. Any actors that are contained by an actor are drawn clipped to the fillRegion . Actor is the most prolific child of Graphic with numerous children of its own. Note: Actors carry with them a lot of information that is required to display them graphically. Thus, you should only use actors for objects that are inherently graphical.x Page 5 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 a c c e p t s d r o p s o f A c t o r Properties of Actor acceptsdrops of Actor This property determines whether the actor requests drop events from SK8. If True (the default), then SK8 will send a drop event to the actor whenever another actor is dropped onto it (typically at the end of a drag process). Getter get the acceptsDrops of me me (an Actor) Setter set the acceptsdrops of me to NewValue me (an Actor) to (a boolean): Whether to tell the actor to accept drop events. Example Let us build a Disposer: a rectangle that removes from the Stage whatever is dropped on it (it sets the container of the dropped actor to false ).

See Also drop , dropped and drag handlers. autohighlight of Actor The autohighlight property determines whether an actor will get highlighted (its set highlight handler will be called) when the mouse goes down on it. The default is False .

If the autotab of the actor is True , pressing the tab sets the keyTarget of its window to the next actor in the Actor's container whose autotab is True . The tabToNextActor handler is called to find the next actor to become the keyTarget . Getter get the autoTab of me me (an Actor) Setter set the autotab of me to NewValue me (an Actor) to (a boolean): Whether to make this actor autotabable. See Also tabToNextActor. bottom of Actor The bottom of the actor's boundsRect . This is a virtual property computed from the boundsRect .

[with relative] (a boolean): If True , the current bottom of the Actor is changed by the amount specified. [with resizing] (a boolean): If True (the default), setting the bottom of the actor constrains all other boundsRect positions to remain as they are. The actor will thus be resized. If False , the actor will move to make its boundsRect coincide with the new bottom position. to (a Number) Example Consider a Rectangle called StickyRectangle . This rectangle has a property called "hostages" in which it keeps a list of actors whose bottoms are constrained to being at the same v coordinate as StickyRectangle 's top . StickyRectangle has another property called "resizing" that specifies whether the hostages will be resized to conform to the constraint. If it is False , the hostages are just moved. We need to redefine stickyRectangle 's moved and resized handlers to make sure that whenever it moves, the bottom of every hostage is kept in line. Notice that if StickyRectangle 's resizing property is False , the hostages's bottom is changed without resizing, in effect moving the hostages as desired. on moved of me (a StickyRectangle) -- Important to do inherited to keep a number of things -- in synch! do inherited set myTop to my top repeat with poorHostage in my hostages set the bottom of poorHostage with resizing my resizing to myTop end repeat end moved See Also setLocation and setBoundsRect , boundsRect , left , top , right , h , v, and location .

In other words, the size of the actor will always exactly match the total space taken up by the actors it contains. As a result, the actor's boundsRect will automatically be constrained to change whenever the boundsRect of any of its contents changes. Default: False . Getter get the boundedByContents of me me (an Actor) Setter set the boundedbycontents of me to NewValue me (an Actor) to (a boolean): Whether to make this actor be bounded by contents. See Also bindByContents . boundsrect of Actor The boundsRect property determines the location of an actor's four corners, and therefore determines the size and location of the actor. Getter get the boundsRect of me with physical Returns a list of four integers: the left, top, right and bottom points enclosing the actor's frame area. The points lie within the frame area. Note: While an actor such as an Oval has no corners, it still has a boundsRect property. In the case of Oval actors, the boundsRect property determines the largest oval in size and shape that can fit within its coordinates.x Page 10 Draft.

This mask is computed automatically by the system from the actor's boundsRect using the makeBoundsRegion handler. Note: If the bounds region is not up to date, the getter for this property forces it to be recomputed by calling makeBoundsRegion . Thus it is a really bad idea to call boundsRegion from within the body of your own makeBoundsRegion . Use getValue instead.x Getter get the boundsRegion of me Page 11 Draft.

See Also makeBoundsRegion . cachespixmap of Actor Getter get the cachesPixmap of me If cachesPixMap is True , then the actor's drawing information will be cached by the system. When an actor's drawing information is cached, the actor is drawn or re-drawn almost instantly. The trade-off is that caching an actor's drawing information uses memory, so if non-cached drawing speeds are acceptable for your project you might choose not to cache an object's drawing information. This property defaults to False . Note: caching will not be effective when the contents of the actor to be cached moves a lot.x me (an Actor) Setter set the cachespixmap of me to NewValue Page 12 Draft.

Thus, the colordepth directly affects the number of colors the actor will be able to display when it becomes a window. The depth can be set as follows: 0 (as many colors as the main monitor can support) 1 (black and white only) 2 (4 colors) 4 (16 colors) 8 (256 colors) 32 (millions of colors), and False (as many colors as the main monitor can support but drawing directly to the screen). Setting the colordepth property to False forces the SK8 graphics engine to draw the actor's components directly on the screen. This saves memory, but it may cause drawing to appear jerky when dragging other windows over the actor. Defaults to 0. Note: every actor in a window is drawn using the same colorDepth : the colorDepth of the window itself (the actor whose container is the Stage ). Thus changing the color depth of an Actor that is inside a window has no effect neither on itself nor on its window.x Getter get the colorDepth of me me (an Actor) Setter set the colordepth of me to NewValue Page 13 Draft.

Can be False , the Stage or another actor. me (an Actor) Setter set the container of me with following to NewValue An actor may be contained by another actor, the Stage , or by nothing at all. Setting the container to False removes the actor from its current container, if any. Setting the container to the Stage makes the actor become a window. The Actor's container is only changed if both the Actor and its potential new container consent to the containment change. This handler, thus, does the following: If there is a new container, calls newContentOk to find out if it accepts the new content. Then the Actor's newContainerOk is called to see if the new container is acceptable. If both these handlers returned True , the operation proceeds and the Actor changes container. Note: An actor may not contain itself. Setting an actor's container to the Stage ensures that the actor and all of the actors that it contains will be graphically visible. To contain an actor in the Stage means that the actor will be drawn over the Stage . Thus, actors directly attached to the Stage behave like windows. It is possible to attach any actor to the Stage : you may thus easily create, e.g., oval windows when the need arises.x Page 14 Draft.

To add something to an actor's contents you have to use the set container handler. See Also set container. dofirstclick of Actor This property specifies whether the actor wants to get a mouseDown event when it is not the selected window and the user clicks on it. If set to False , when the actor is a window and it is clicked on, it gets an activate event. If set to True , in addition to the activate event, a mousedown event is sent. Page 15 Draft.

Getter get the doubleClickStyle of me Returns the manner in which an actor combines mouseDown events into clicks/ doubleClicks. The options are: 'standard' : clicks and doubleclicks are generated when appropriate. 'clickOnly' : no doubleClicks are generated. 'doubleClickOnly' : no clicks are generated.

Setting the draggable property of an actor to True restores its ability to be dragged by the mouse. Note: This property only prevents the drag handler from dragging the actor (drag does nothing if the Actor's draggable is False ). It will have no effect on any other handlers that you could use to do the dragging by hand.x Getter get the draggable of me me (an Actor) Setter set the draggable of me to NewValue me (an Actor) to (a boolean) Example To explain the note above, we could try to implement the drag handler ourselves. We could write a simple version of it as shown below. Since this handler does not check the draggable property, the property will have no effect on whether you can drag the actor or not. The draggable property only works if you use the built-in drag handler. on drag of me (an Actor) repeat while the mouse is down set {h,v} to the mouseloc of the Stage -- since the mouseloc of the Stage is always returned -- in physical coords, set the physical location! set my location with physical to {h,v} end repeat end drag fillColor of Actor This property specifies the Renderer that is used to render (draw) the actor's fillRegion .

Getter get the keytarget of me me (an Actor) Setter set the keytarget of me to NewValue Makes the actor in the to argument be the recipient of the actor's key events. Setting the keyTarget of an actor not contained by the Stage has no effect. When the actor is a window, the new keytarget actor (which should be in its contents) gets an activateText message. A window may have either zero or one keyTarget actor. Typically, this will be an editable text field.

The layer is a positive integer in the range of 1 to the number of actors in its container's contents. Lower-numbered actors cover higher-numbered actors. Note: Every SK8 actor is assigned a layer. If an actor contains eight actors, each contained actor is numbered from 1 to 8. Objects receive their number in the order they appear in the contents of their container, i.e., from front to back, starting from 1. When dealing with graphics, the layer property determines the precedence by which actors cover or are covered by other actors. Lower-numbered actors cover higher-numbered actors. Warning: Exercise care when referencing an actor by its layer property when writing scripts, since an actor's layer is never permanently assigned (use the actor's objectName instead). Layer properties exist only to show an actor's place among other actors of its kind. If, for example, an actor contains eight actors, deleting the first contained actor will cause each of the remaining actors to have the value of their layer property reduced by one (valid actor numbers would now be from 1 to 7). Similarly, setting the layer of the highest numbered actor to 1 automatically raises the layer of all other actors sharing the container by 1.x Getter get the layer of me me (an Actor) Setter set the layer of me to NewValue me (an Actor) to: A positive integer.

Mouse-related events are generated through the mouse, and include events such as mouseEnter, mouseLeave , mouseUp , and click . Under normal circumstances (when mouseSensitivity is set at its default normal value), mouse-related events that occur over an actor's contents are sent to the actor's contents. If, however, the event happens over the container actor and not over any of the contained actors, the event is sent to the container actor. When an actor's mouseSensitivity is set to opaque , all mouse-related events that happen within it or its contents are sent to itself: the contents become isolated from mouse events. When an actor's mouseSensitivity is set to transparent , all mouse-related events are sent to the actor's contents, and never to the container actor; if a mouse-related event happens within the actor, but does not occur within any of the contained actors, no event is accepted. The transparent setting keeps the container actor from ever receiving mouse-related events. When an actor's mouseSensitivity is set to invisible , the actor becomes invisible to mouse events, and all its contents become invisible with it. The actor and its contents are not 'seen' by the event system. Finally, when an actor's mouseSensitivity is set to custom , the actor can do its own tests to determine whether it has been hit by the mouse. Each time the system wants to determine whether such an actor has been hit, the handler hitByMouse is called. The actor then performs its arbitrary test, returning True or False as appropriate. The mouseSensitivity can be one of 'normal' , 'opaque' , 'transparent' , 'invisible' or 'custom' . Getter get the mouseSensitivity of me me (an Actor) Setter set the mousesensitivity of me to NewValue me (an Actor) to: One of 'normal' , 'opaque' , 'transparent' , 'invisible' or 'custom' .

As a result, the entire contents of the actor pans to accommodate the new origin. Calls setOrigin to do the work. Note: If the forceRedraw argument is False the system optimizes the operation making it considerably faster. There are a number of circumstances, however, in which this optimization results in draw errors. In particular, the actor to be panned should not be covered in any part by any actors in its window. Also the actor (or anything in it) may not be rendered with renderers that do not render masks uniformly (like an imageRenderer that paints a PICT as opposed to something like Red ). In general, a redraw error when panning is a clear indication that you cannot use this optimization and thus should call this handler with the forceRedraw argument set to true .x me (an Actor) [with forceredraw] (a boolean): If True (the default) , everything in the Actor is redrawn. to: A list of two numbers.

This property, thus, acts like the draggable property.x Defaults to True . Getter get the resizable of me me (an Actor) Setter set the resizable of me to NewValue me (an Actor) to (a boolean) See Also draggable . resizescontents of Actor If the resizesContents property of an actor is set to True , whenever the boundsRect of the actor grows or shrinks, the boundsRect of all of its contained actors proportionally adjust in size and location. Note: Setting this property of actor X to True makes X resize its subactors when it itself is resized. There is a caveat, however: in order for this to work SK8 caches the rects of its contents when the property is set. The cache will move out of synch when any of the subactors are moved or resized! Therefore, it's important that you recache the rects –– in this case, by calling the cacheContentsRects handler on X.x Defaults to False .

Setter set the right of me with physical with relative with resizing to NewValue me (an Actor) [with physical] (a boolean): If True , assumes that the right is specified in physical coordinates. [with relative] (a boolean): If True , the current right of the Actor is changed by the amount specified. [with resizing] (a boolean): If True (the default), setting the right of the actor constrains all other boundsRect positions to remain as they are. The actor will thus be resized.

The ProgressBar would be a rectangle with a rectangle inside it. Let's make the main object: new rectangle with objectName "ProgressBar" with size {100,20} addProperty ProgressBar, 'percentageCompleted' We added a property to keep track of how much of the task we keep track of has been completed. Next, we make the Black rectangle that shows the progress. new rectangle with objectName "ProgressBarBar" set the container of ProgressBarBar to ProgressBar set the boundsRect of ProgressBarBar to {0,0,2,20} So, in the initial state, our ProgressBar is a white rectangle with a little black rectangle in the left side. We complete the work by writing the set percentageCompleted handler to update the black bar. We assume the percentage is a number between 0 and 100. on set percentageCompleted of me (a ProgressBar), percent -- call the next handler to set the property! do inherited -- now set the right of the progressBarBar to the percent. set the right of item 1 in my contents to percent end set percentage We can now test our object by putting it on the Stage and typing into the messagebox something like: repeat with i from 1 to 100 set the percentageCompleted of the ProgressBar to i end repeat See Also setLocation and setBoundsRect , boundsRect , left , bottom , right , h , v, and location . scale of Actor Specifies the actor's scale. The default scale is {1,1} . A scale of 1 means that if the logical width of an actor in the Actor's contents equals 100, that actor is 100 pixels wide. Setting the scale to 2 doubles the number of pixels required per logical unit (the actor would be 200 pixels wide). Getter get the scale of me me (an Actor) Page 35 Draft.

SetScale is called to do the work. me (an Actor) to: A list of 2 positive numbers. Example Consider a rectangle called ZoomRect containing a square in its top left corner. The scale of ZoomRect is {1,1} . new rectangle with objectName "ZoomRect" with container Stage with boundsRect {100,100,300,300} new rectangle with objectName "InnerSquare" with container ZoomRect with boundsRect {2,2,22,22} The following command will double the square's size: set ZoomRect's scale to {2,2} One thing to note is that the square's top left corner, which used to be 2 pixels away from ZoomRect 's topLeft corner, is now 4 pixels away. In fact, every actor inside ZoomRect would double the physical distance between its topLeft and ZoomRect 's topLeft. set ZoomRect's scale to {0.5,2} This command will flatten InnerSquare into a vertical rectangle. InnerRect appears to have been stretched vertically while it was shrunk horizontally. Note that if we got the boundsRect of InnerRect (the logical boundsRect ), we would still get the original boundsRect : {2,2,22,22} . See Also setScale ,, rescaled zoom , hscale , and vscale . size of Actor Specifies the width and height of the actor's boundsRect .

If the size specified is smaller than the minimumSize , the size is set to the minimumSize . me (an Actor) [with relative] (a boolean): If True , the widht and height provided are added to the current width and height to compute the new size.

Example get the size of Actor with physical See Also setSize and setBoundsRect , and boundsRect . Text of Actor Specifies the actor's text string. If there is no text string, the text property returns "". The text draws itself at the center of the actor. The textLocation , textVOffset and textHOffset properties let you change the position. You can also change the text's font, size and color using the textFont , textSize and textColor properties. Actors can only display one line of text. You cannot refer to ranges in non-EditText actors; and therefore, you cannot have mixed fonts. Getter get the Text of me with start with end Page 37 Draft.

See Also the fonts of the System . texthoffset of Actor Specifies the horizontal offset of an actor's text from the location specified by the textLocation property. The textHOffset positions an actor's text to the right of the location specified by the textLocation property by the number of pixels specified in the textHOffset property's argument. If the number specified in the textHOffset argument is negative, the text is offset to the left. Defaults to 0.

The first word of the setting (top, center, or bottom) controls the text's vertical positioning within the actor (with the notable exception of the use of center instead of centerCenter). The second word of the setting (left, center, or right) controls the text's horizontal positioning within the actor. For example: text given a horizontal value of left will be left-aligned; text given a horizontal value of center will be center-aligned; and text given a horizontal value of right will be right-aligned. The textLocation can be adjusted further by use of the textHOffset and textVOffset properties. Defaults to 'center' . Note: the textLocation does not affect the justification of text in EditText actors. Use the justification property for that.x Getter get the textLocation of me me (an Actor) Setter set the textlocation of me to NewValue me (an Actor) to: One of 'topLeft' , 'topRight' , 'topCenter' , 'centerLeft' , 'centerRight' , 'center' , 'bottomLeft' , 'bottomRight' , 'bottomCenter' . Example The Label is a rectangle that resizes itself in order to always show all its text . When the Label changes size, it does so in accordance with the textLocation property: if the textLocation is 'topleft' , 'centerLeft' or 'bottomLeft' the text is left justified, meaning that the left margin should stay constant. This means that in this case Page 41 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 t e x t o f f s e t o f A c t o r the label will resize keeping its left in the same place. If the text is right justified, the right is kept constant, and if it is centered, the center is kept constant. We define a handler called bindLabelText which we will call each time the Label 's text size can change. For simplicity, assume that all we care about is the horizontal size of the actor (we will not change the vertical size). on bindLabelText of me (a Label) set {h,v} to my actorTextSize set tl to my textLocation if tl='center' or tl='topCenter' or tl='bottomCenter' then -- simplest case: setting the width preserves the center. set my width to h else if tl='topLeft' or tl='centerLeft' or tl='bottomLeft' then -- preserve the left! set my right to my left + h else -- preserve the right! set my left to my right - h end if end if end bindLabelText See Also textHOffset and textVOffset . textoffset of Actor Specifies the number of pixels of offset from the Actor's textLocation to the point where the text is actually drawn. This property, in conjunction with the textLocation property, can be used to let you move the actor's text to any position within the actor. Note: this property does not affect the text in EditText actors.x Getter get the textOffset of me Calls textHOffset and textVOffset to get the values. me (an Actor) Setter set the textoffset of me to NewValue Calls set textHOffset and set textVOffset to do the work.

When the value of the visible property is set to False , the actor is invisible. Conversely, setting the visible property of an actor to True will make the actor visible (assuming the actor is not covered by other actors). If an actor is not attached to a container, then it will not be shown, regardless of the setting of its visible property. Page 46 Draft.

SK8 keeps a list of all actors and objects that have their wantsIdle property set to True . When an idle event is sent, it is sent to each object on the list when they are contained by the Stage . Actors that have their wantsIdle property set to False are never sent idle events. Default: False . Note: Since time is taken to send each idle event, keep the wantsIdle property set to False for all actors that don't make use of idle events. Otherwise, your project will be unnecessarily slowed.x Getter get the wantsIdle of me me (an Actor) Page 48 Draft.

When the value of an actor's wantsMouseWithin property is set to False , the mouseWithin handler does not get called when the pointer is over the actor. Note: Note that repeatedly calling mouseWithin will slow the system down. Therefore, only use this feature when it is really needed. For most cases, mouseEnter and mouseLeave suffice.x Default: False .

Handlers of Actor activate of Actor activate me This handler is called when the Actor is a window and it is clicked on (the window is selected). It is useful in allowing the alter the window's appeareance slightly to show its new, active status. me (an Actor) Example It could be a convention in your favorite window system to show that windows are active by setting their framecolor to UiRectangleOutBevel , a BevelRenderer. All we need for this is to redefine the activate handler to do it. Let's do this for an imaginary rectangle called compliantWindow. Page 50 Draft.

The default handler does nothing. me (an Actor) activateText me See Also keyTarget . actortextsize of Actor actorTextSize me with thetext Returns the size of the text of an actor in pixels. me (an Actor) [with thetext] (a String): If theText is False (the default), the Actor's text is used to compute the rect required. Otherwise the string provided in theText is used. This is useful in determining how big the Actor would be if its text was theText and all its text attributes remained the same. Example If you want an actor to be like a Label in that its size is the size of its text you can say: Most of the work involved in writing the Label actor was making sure the line above was included in the right places. The Label changes its size whenever its text changes size. set my size to my actortextsize Page 51 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 a d d c o n n e c t o r o f A c t o r This will definitely happen when the text changes. Thus, we can achieve this functionality by defining the set text handler as follows: on set text of me (a Label) to newValue -- important to do inherited to actually set the text! do inherited set {h,v} to my actorTextSize set my size to {h,v} end set text The Label also does this when the textFont , textStyle or textSize change. addconnector of Actor addConnector me, theconnector Adds theConnector to the actor's connectors.

Example Consider an actor, called TypingTutor, that tries to teach good typing techniques to the user. One thing it might want to do is let the user know that she has left a key down for too long, causing an autokey event. The handler could beep and then ignore the event as follows: on autokey of me (a TypingTutor), character -- to ignore the key do not call the next handler. beep end autokey See Also keyDown . bestsize of Actor bestSize me This handler is called to ask the actor to compute its best size. The default handler does nothing. Note: In general this handler is not automatically called by the system. This handler is documented as an example of a nice, object oriented, way to implement layout constraints. If you want it called for your objects you have to redefine resized as shown in the example.x me (an Actor) Example In this example we show how bestSize can work together with resized to implement automatic layout maintenance of actors. Consider a menubar called SnappingMenubar, contained by a rectangle called ConsiderateContainer. The menubar always wants to stay at the top of its container, adjusting its width to match its container's. We define its bestsize and the resized of its container to call bestsize of everything in its contents. Page 53 Draft.

See Also resized . bindbycontents of Actor bindByContents me Makes actor bind its contents. This involves two steps: computing the rectangle that would bind all contents (even invisible ones), resetting the origin of the Actor so that the contents stay in their place on the screen, and changing the boundsrect of theActor to the new rectangle. This handler is called when you set the boundedByContents of an Actor to True . However, you can call it for any actor if you wish to achieve a temporary boundedByContents effect. me (an Actor) See Also boundedByContents . bringcloser of Actor bringCloser me The bringCloser handler brings the actor closer to the top of its container's contents. This is accomplished by lowering the actor's layer property by one (if the actor is not already the topmost actor in its window). me (an Actor) Page 54 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 b r i n g t o f r o n t o f A c t o r Example We define a new handler for Actors called "floatUpToSurface," which keeps increasing the actor's layer until it is at the front of its container. Each time the actor comes closer, a BubbleSound is played. on floatUpToSurface of me (an Actor) repeat until my layer = 1 bringCloser me play BubbleSound -- wait for half a second for effect. wait 0.5 seconds end repeat end floatToSurface See Also bringToFront , sendFarther, sendToBack and set layer. bringtofront of Actor bringToFront me The bringToFront handler brings the actor to the front of its container's contents. This is equivalent to setting the Actor's layer to 1. me (an Actor) Example Consider a RoundRect (a button), called PullerUp , whose sole purpose in life is to bringToFront an actor when it is clicked on. PullerUp has a property called "subject," which stores the Actor that will be brought to the front. This property can be set directly by the user or by dropping an actor onto PullerUp . For this, we need to define its dropped handler as follows: on dropped of me (a PullerUp), dropee set my subject to dropee end drop Now we define the click handler to bring the subject up if there is one. on click of me (a PullerUp) -- make sure a subject is available. if my subject then bringToFront my subject end if end click Page 55 Draft.

It might be desirable to reset the UI to its original state by bringing up all the windows that are up originally. This could be tied in to a menuItem called RestoreUIWindows , using a global variable called uiWindows. We define the menuSelect handler as follows: on menuSelect of me (a RestoreUIWindows) global uiWindows bringUp every item in uiWindows end menuSelect changeparents of Actor changeParents me, newparents This handler makes is makes sure that the actor redraws itself in order to show possible changes in its geometry resulting from the change of its baseParent . me (an Actor) newparents clearselection of Actor clearSelection me This handler is called to clear the Actor's selection. The system will automatically send this message to the keyTarget of the active window when the user selects "Clear" from a menu.

A click event is defined as the user pressing and releasing a mouse button over an actor. The time allowed between the press and the release of the mouse button varies by system according to a setting made in the control panel. Note: The default mouseUp handler of Actor determines whether a click event should be generated by taking into consideration the time elapsed between mouseDown and mouseUp and the Actor's doubleClickStyle . If you are not getting clicks make sure the default mouseUp of Actor is being called and the doubleClickStyle is set properly.x me (an Actor) The default handler sends the click to the Actor's container. See Also mouseUp , and doubleClickStyle . close of Actor The close handler is called when the actor is a window and its window gets closed using Command-W, or choosing Close from SK8's File menu. The default handler sets the actor's container to False . me (an Actor) close me commandkeyevent of Actor The commandkeyevent handler is called on the currentCommandKey of the System when the user types Command-character.

Consider a rectangle called MyControlPanel which contains a menubar with menus and menuItems. Some of the menuItems have their commandKey property set. When MyControlPanel becomes the current window, we want the menubar to get all commandKey events. For this, we redefine the activate and deactivate handlers as follows: on activate of me (a MyControlPanel) -- It is important to call the next handler! do inherited set the currentCommandKey of the System to theMenubar end activate Since we don't want the menubar to get commandKeyEvents when the window is no longer active, we should set the currentCommandKey of the System to False when the window deactivates. on deactivate of me (a MyControlPanel) -- It is important to call the next handler! do inherited set the currentCommandKey of the System to false end deactivate Now, whenever the user presses a key and the command key, a commandKeyEvent is sent to theMenubar (the commandKeyEvent of Menubar actually finds a menuItem matching the key and invokes its menuSelect handler). See Also currentCommandKey of System . connect of Actor connect me, endActor with theconnector with newconnector The connect handler lets you provide a connector to use for the connection or specify a connector to make a child of. The two optional arguments, theConnector and newConnector, are used for this purpose. When newConnector is False , no connector is Page 58 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 The connect handler connects the actor and the endActor with the specified connector. When two actors are connected, a connector is drawn from one to the other. The connector's ends stay with the actors when the actors move. The actor becomes the startActor of the connector and endActor becomes the endActor of the connector. c o n n e c t e d o f A c t o r created and the connection is made using the connector passed as theConnector. Thus, theConnector should be provided in this case. me (an Actor) endactor (an Actor) [with theconnector] (a Connector or [[False]]): If False , a child of Connector is made. Otherwise, a child of theConnector specified is made. [with newconnector] (a boolean): If True , a new connector is made to make the connection. Example Let RandomConnector be a rectangle that on mousedown , connects two actors in its contents at random. The simplest thing we can do is use a new connector each time. We define the mouseDown handler below. The call to connect in the handler below creates a new child of Connector and uses it for the connection. Thus, each time we mousedown an extra connection is added to the RandomConnector. on mousedown of me (a RandomConnector) set theContents to my contents -- pick the first actor and remove it from the list. set startActor to any item in theContents remove startActor from theContents -- pick the second actor. set endActor to any item in theContents -- Connect them! connect startActor, endActor end mousedown We might want just one connection to exist, and keep changing it to other actors each time we mousedown. We might have a connector set aside just for this purpose, called oneConnector. To achieve, this we need to replace the last line of the handler with connect startActor, endActor with theConnector oneConnector with newConnector False Notice that if newConnector had been True , the connection would have been made with a child of the connector specified in the theConnector argument (oneConnector in this case). connected of Actor connected me, otheractor, theconnector Page 59 Draft.

OtherActor is the actor to which it has been connected and theConnector is the connector used for the connection. me (an Actor) otheractor (an Actor) theconnector (a Connector) Example Consider an Actor, called startPoint , that does not want to be at the end of any connection (it does not want to be the endActor of any connector). This can be done by defining its connected handler to reverse a connection just made when the actor is at the wrong end of it. on connected of me (a startPoint), otherActor, theConnector if theConnector's endActor = me then reverseConnection theConnector end if end connected See Also connect , reverseConnection . connectedactors of Actor connectedActors me Returns all actors that are directly connected through connectors to the specified actor. me (an Actor) connectedfrom of Actor When a connection is made with connect , the first actor becomes the startActor of the connector and the second becomes the endActor. Thus, the connection can be seen as directional: going from the startActor to the endActor. connectedFrom me The connectedFrom handler exploits this directionality. It gets all of the actor's connectors whose endActor equals the actor and returns all the actors at the other end: the startActors from which this actor is connected. me (an Actor) Page 60 Draft.

At each time interval, each component checks its inputs and computes its outputs. The connections can be implemented with connectors. If the component is an AndGate , we would write the following handler: on computeValue of me (an AndGate) -- get the outputs of the components hooked up to the gate. set inputs to the output of every item in my connectedFrom -- Find out if there are any zeroes repeat with oneValue in inputs if oneValue = 0 then set zeroFound to true exit repeat end if end repeat -- now set the output property. if zeroFound then set my output to 0 else set my output to 1 end if end computeValue See Also connect , startActor, endActor, connectedTo , connectors . connectedto of Actor When a connection is made with connect , the first actor becomes the startActor of the connector and the second becomes the endActor.

It gets all of the actor's connectors whose startActor equals the actor and returns all the actors at the other end: the endActors to which this actor is connected. me (an Actor) connectedTo me Example Consider an actor called Colorizer that sets the fillcolor of every item it's connected to to its fillcolor. For this, we redefine the set fillcolor handler as follows: Page 61 Draft.

This is constructed by walking up the containment hierarchy from the actor to it's window. Note that this will not include the stage. me (an Actor) copyselectiontoclipboard of Actor This handler gets called when the actor is the keyTarget of the active window and the user keys COMMAND-C (or selects "Copy" from a menu item).

The default handler does nothing. me (an Actor) cutSelectionToClipBoard me deactivate of Actor deactivate me Deactivate is called when the Actor ceases to be the active window. You can use this handler to provide a visual indication that your window is no longer the selected window. me (an Actor) Example It could be a convention of your favorite window system to show that windows are active by setting their framecolor to uiRectangleOutBevel , a BevelRenderer. When windows deactivate, their framecolors are set to Black . To make this happen, we redefine the deactivate handler of an imaginary rectangle called compliantWindow. on deactivate of Object (a CompliantWindow) -- It is important to call the next handler! do inherited -- Now set the frameColor to Black set my framecolor to Black end deactivate See Also activate . deactivatetext of Actor The deactivateText handler is called when the actor ceases to be the keyTarget of its window or when the Actor is the keyTarget and its window ceases to be the active window.

An error is reported if the two actors are not connected. me (an Actor) otheractor (an Actor) doubleclick of Actor A doubleClick event is sent to an actor whenever the user double clicks the mouse button on it. A doubleclick event is defined as the user pressing and releasing a mouse button over an actor twice. The time allowed between the press and the release of the mouse button varies according to a setting made in the Macintosh control panel. The default behavior for double clicking on and actor object is to pass the doubleClick event on to the actor's container. Note: The default mouseUp handler of Actor determines whether a doubleClick event should be generated by taking into consideration the time elapsed between mouseDown and mouseUp and the actor's doubleClickStyle . If you are not getting doubleClicks make sure the default mouseUp of Actor is being called and the doubleClickStyle is set properly.x me (an Actor) doubleClick me See Also mouseUp and doubleClickStyle .

After invoking the drag handler, the actor's location is set to the pointer location of the next mouseUp. me (an Actor) [with otheractors]: A list of other actors which should be dragged along with the dragged actor (if no other actors should be dragged, the otherActors argument should be False ). [with live]: A Boolean value that indicates whether the drag should be live, or whether only the grayed outline of the dragged actor(s) should be dragged. [with dropevents] (a boolean): If True , when the drag ends, a dropEvent is sent to the frontmost actor that accepts drop events under the mouse. [with draggedoverevents] (a boolean): If True , then every time the dragged actor enters another actor that actor gets a draggingMouseEnter. When it leaves it gets a draggingMouseLeave. [with draggingmousewithinevents] (a boolean): If True , the draggingMouseWithin is continuously sent to the actor under the actor being dragged. DraggedOverEnter and draggedOverLeave events are sent too. [with onstage] (a boolean): If True , the actor pops up on the Stage to be dragged as a window. Only one actor at a time can be dragged this way. At the end of the drop the actor returns to its original location and container. [with constrainingrect]: A list of 4 integers specifying a rectangle (in Stage coordinates). The actor that is being dragged will be constrained to be always within this rect. Example Since any dragging operation ends as soon as the mouse button is released, it is common to call this handler on mousedown . The mouseDown handler is shown below. on mousedown of me (a DragEagerActor) drag me end mousedown Notice that all actors contained by the DragEagerActor will be automatically dragged with it, thanks to the containment hierarchy.

The default handler just sends the dropped event to the drop recipient (the actor right under the actor being dragged). me (an Actor) droprecipient: The actor under the mouse at the place where the mouse went up. drop me, droprecipient Example The most common thing we want to do after a drop event is to set the container of the droppedActor to the actor. We also want to preserve the physical location that the droppedActor had just before the drop took place, so that there is no visible "jump" when the drop takes place. To make this happen, we have to get the physical location before we change the container of the droppedActor and restore it after we change the container. We define a dropped handler on an actor called DropMagnet . Note that it is necessary to lock the new container in order to avoid showing the change of location. on dropped of me (a DropMagnet), dropee lock me set {h,v} to the location of dropee with physical set the container of the dropee to me set the location of the dropee with physical to {h,v} unlock me end drop See Also dropped and drag . dropped of Actor dropped me, droppee Dropped is called to tell actor that the droppee is being dropped into it (typically at the end of a drag process). It is the responsibility of the actor to change the container of the droppee if wanted. The default handler does nothing. Page 68 Draft.

The default handler does nothing. This handler is provided to allow you to do low level set up which very rarely will need to be done. Note: This handler is for advanced, low level users only. If you redefine it, keep in mind that you cannot do anything in it that would force a graphical update of your actor (or any of its containers). So, changing boundsrects, setting fillcolors, etc. is not advisable. Operations at that higher level can be done by redefining the set container handler.x me (an Actor) enteringStage me fillboundsrect of Actor fillBoundsRect me with physical Returns the boundsRect of the Actor's fillRegion in Stage coordinates. me (an Actor) [with physical] forceredraw of Actor The forceRedraw handler forces the actor to completely redraw itself and its contents. In addition to this, all actors in the deepContents of the actor (and the actor itself too) will recompute all their regions. Note: You should have a good reason for calling this handler since it is expensive! It recomputes and redraws everything below the actor you specify. For most cases, lightForceRedraw is a better choice.x me (an Actor) forceRedraw me Page 69 Draft.

This handler, which should be called from mouseDown only, starts drawing an outline of an actor from the start point (or the location of the mouse). When the mouse is released, the resulting boundsRect is returned. You can see this handler in operation each time you use a tool from the DrawPalette to draw an actor. If the start point is not specified, the mouseLoc of the Stage is used. me (an Actor) [with starth] (an Integer): The horizontal position of the start point in Stage coordinates. [with startv] (an Integer): The vertical position of the start point in Stage coordinates. [with style]: Specifies how the drawing of the rect outline will take place. Options are 'centerOut' and 'cornerToCorner' . [with shiftconstraint] (a boolean): If True , constraints the boundsrect to be a square. [with multipledraw] (a boolean): If True allows drawing of multiple actors. [with boundsrectset] (a boolean): If True , sets the boundsRect of the Actor (me) to the boundsRect specified by the user. hascontents of Actor hasContents me Returns True if the actor has any contents. me (an Actor) hide of Actor hide me Page 70 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 h i t b y m o u s e o f A c t o r The hide handler makes the actor specified in the argument invisible by setting its visible property to False . Contained actors disappear because their container is invisible. This handler does not, however, change the visible property of the contained actors. me (an Actor) Example hide Actor See Also set visible . hitbymouse of Actor The hitByMouse handler is called by the system to check whether actor has been hit by the mouse when the actor's mouseSensitivity is 'custom' and the location of the event falls within the actor's bounds. The h and v arguments are given in Stage coordinates. By redefining this handler it is possible to specify in arbitrary ways whether the actor is visible to the event system or not. The hitByMouse handler should return True or False . The default handler returns False . hitByMouse me, x, y me (an Actor) x (an Integer): A horizontal point in Stage coordinates. y (an Integer): A vertical point in Stage coordinates. Example Consider an actor that is only visible to the event system when its fillcolor is Red . First, we set its mousesensitivity to 'custom' and then we define the hitByMouse handler. set the mouseSensitivity of VisibleWhenRed to 'custom' on hitByMouse of me (a VisibleWhenRed), h, v if my fillcolor = Red then return true else return false end if end hitByMouse Page 71 Draft.

The actor must be contained by the Stage for hMouse to be valid. The coordinate system continues outside of the actor's boundaries, so even if the mouse pointer is outside the actor, an appropriate value will be returned. me (an Actor) Example get the hMouse of Actor See Also mouseloc . idle of Actor idle me Idle events are sent by SK8 when the user is generating no events through the keyboard or mouse, and when no handlers are running. The idle event is sent to every actor that is on the Stage (or contained by an actor on the Stage ) and has its wantsIdle property set to True . me (an Actor) Example Consider a actor serving as a digital clock. Let's call it DigClock . DigClock is a rectangle attached to the Stage whose text is the current time. DigClock 's wantsIdle property is True , since DigClock needs idle events to update its text . We define the idle event to set DigClock 's text to the current time (we use the Today object for this). on idle of me (a DigClock) set my text to Today's timeString end idle Page 72 Draft.

If first does the inherited handler to let the object system create a new object. After that it does all the set up required to make an actor. This involves copying all the contents of the original actor. The handler creates and sets up connectors for any actors in its contents that are connected. It is common to redefine this handler to do any extra set up that may be required for your actors. If you need to redefine it, make sure you do inherited before doing your own set up. me (an Actor) original: Original is either the object which was passed to new or duplicate to create a child or sibling, respectively. child: Child is a boolean which is True when Object was created with new and False when Object was created with duplicate. args: Arguments is a list of property-value pairs which are passed to new or duplicate to initialize the properties of Object. Example In SK8, when an object is created, all the values of its properties are initialized from the values in the properties of the parent. If this mechanism was not in place already, we could implement it in the initialize handler. For example, we can write an initialize handler that makes sure the fillcolor of the new actor is the fillcolor of the original. Let us call the actor that presents this behavior a "fillcolorInheritor ". Page 73 Draft.

You can use initializeFromStore to perform any special load-time intialization for your objects. InitializeFromStore -- not initialize --is called at load-time. The difference between the two is that an object is not created when loaded, but only brought into memory. InitializeFromStore is responsible for performing all initialization required for the object to be functional (e.g., open media files). In the actor's case, it initializes the actor's regions. me (an Actor) keydown of Actor keyDown me, thechar The keyDown handler is called when the user presses down on a key and the actor is the keyTarget of its window. me (an Actor) thechar: The character pressed. keyup of Actor keyUp me, thechar The keyUp handler is called when the user releases a key and the actor is the keyTarget of its window.

The default handler marks the boundsRegion as valid and returns. The children of Actor all redefine this handler to specify their particular geometries. Note: calling boundsRegion to get the bounds region will call makeBoundsRegion if the region is not up to date. Thus, you should not call the getter to get the region, and should use getValue instead.x me (an Actor) See Also boundsRegionOk . makefillregion of Actor makeFillRegion me Recomputes the fill region of the actor (the bounds region minus the frame region).

An example would be to change the cursor. The EditText changes the cursor to the ibeam cursor to show that text editing is allowed within itself. On mouseleave , it is good policy to undo your changes. Thus, we could set the cursor of the Stage to the StandardCursor. on mouseEnter of set the cursor end mouseEnter on mouseLeave of set the cursor end mouseEnter me (a EditText) of the Stage to the iBeamCursor me (a EditText) of the Stage to the StandardCursor See Also mouseSensitivity, set cursor of the Stage . mouseleave of Actor mouseLeave me Called on the actor whenever the pointer leaves the actor's bounds. me (an Actor) See Also mouseEnter for an example of using this handler. mouseloc of Actor mouseLoc me Returns a two-item list of the logical mouse position in the specified actor's coordinate system. The coordinate system continues outside of the actor's boundaries, so even if the mouse pointer is outside the actor, an appropriate value will be returned. Note: The actor must be contained by the Stage for mouseLoc to be valid. Otherwise an error is signaled.x me (an Actor) Page 80 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 m o u s e u p o f A c t o r Example As an exploratory example, consider an actor whose text is its mouseloc . For that, let's write a mouseDown handler that keeps setting the actor's text to its mouseLoc . Notice the values of the mouseLoc when you move the mouse outside the bounds of the actor. It would also be instructive to test our handler after changing the scale and the origin of the mouseLocTester. on mouseDown of me (a mouseLocTester) repeat while the mouse is down set my text to my mouseloc as a String end repeat end mouseDown See Also origin and scale . mouseup of Actor mouseUp me Called on the actor whenever the pointer (a mouse, pen, or other pointing device) goes up on it. Note: The default mouseUp of Actor determines whether clicks or doubleClicks should be dispatched. Thus, if you redefine this handler, you should do inherited if you want these events to be generated.x me (an Actor) Example The mouseUp event is very convenient because it is always sent after a mousedown , a click or a doubleclick . So, if you want something to happen when the mouse goes down over an actor, without caring whether a click or a mousedown was generated, mouseUp is the best thing to define.

This means that there is code which might draw into the Actor at other times than the normal draw loop. Only a few actors know how to take advantage of this property (e.g. EditText ). Setting it on other actors has no effect. It is provided for the advanced user to allow the creation of custom actors that use the ownedRegion virtual property. ownsRegion me When ownsRegion is True , the graphics system makes sure to draw the actor every time something in its window is drawn (this slows down all drawing in the window a bit). The graphics system will also maintain in the ownedRegion property, the region that you should clip to when you want to draw directly to the screen. You will write a handler that updates your actor graphically directly (without invoking the draw loop).

If newContainer is False , the actor is being removed from its container. Otherwise, newContainer is an actor. This handler is called to allow the actor to do any extra set up required to be added to newContainer. The default handler does nothing.

Note: If otherActors are specified, the resizing is done non live.x me (an Actor) how: Specifies which part of the actor's boundsRect the user is going to grab for resizing. Options are 'top' , 'bottom' , 'left' , 'right' , 'bottomRight' , 'bottomLeft' , 'topLeft' , 'topRight' . [with live] (a boolean): If True the actor's total image will be constantly re-drawn as the user moves the mouse for resizing. If False only the outline of the actor's image will be constantly re-drawn as the user adjusts the object to a new size. If this argument is not specified, we resize live when the optionKey is down. [with otheractors]: A list of actors to be resized at the same time. resized of Actor resized me The resized event is sent each time an actor's boundsRect is set with the justMoving flag set to False (the default). The default resized handler ensures that any connectors stay connected at the right places and that the container resizes itself if it is bounded by contents. You can modify the resized handler to create special behaviors whenever a resized event occurs. A titlebar, for example, would always want to span the whole width of its container. The container, then, can use the resized handler to make sure that each time it changes size, the titlebar does too. It is good object-oriented programming style, of course, to encapsulate the knowledge required to resize an object in the object itself. Thus, whenever the actor gets resized, it calls the bestSize handlers for each item in its contents. Through the bestSize handler, then, each object knows how to resize itself. me (an Actor) Page 91 Draft.

This is useful when you are writing a tight loop moving windows around the screen and the graphic system is unable to get a chance to refresh the windows. Therefore, if you ever are whizzing windows around and things don't look right, try calling this handler on each window you wish to refresh. Note this is different from forceRedraw and lightForceRedraw. Those two functions tell the graphic system that the windows need to be refreshed. sendUpdateEvent forces the windows to be refreshed. me (an Actor) setboundsrect of Actor setBoundsRect me, left, top, right, bottom with physical with relative with justmoving Page 94 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 s e t b o u n d s r e c t o f A c t o r The boundsRect property determines the location of an actor's four corners, and therefore determines the size and location of the actor. This handler sets the actor's boundsRect. If you change the boundsRect of the actor without changing its size, set justMoving to True . This allows setBoundsRect to internally optimize the speed in which the actor is moved. If you incorrectly set justMoving to True but nonetheless change the size of the actor, you may experience some redraw problems. Also, if justMoving is True , a moved event is sent to the actor. Otherwise, a resized event is sent. Note: If the boundsRect specified is smaller than the actor's minimumSize , the boundsRect is set to the minimumSize . This is the handler that is called when any actor changes size , location or both. If you want to intercept any of these property changes, redefining setBoundsRect is the way to do it.x me (an Actor) left (a Number): The horizontal position of the left of the actor's boundsRect. top (a Number): The vertical position of the top of the actor's boundsRect. right (a Number): The horizontal position of the right of the actor's boundsRect. bottom (a Number): The vertical position of the bottom of the actor's boundsRect. [with physical] (a boolean): If True , the values supplied are assumed to be in physical (Stage ) rather than logical coordinates. The default is False . [with relative] (a boolean): If True , this handler interprets the four values as offsets from the current values. The default is False . [with justmoving] (a boolean): Whether the actor is going to change size as a result of this operation. If the actor will not change size, this argument should be True . Example Consider a rectangle called FlakyRect that shrinks by one pixel in every direction while the mouse is down on it. If the optionKey is down, it expands by one pixel each time. Suppose we have placed FlakyRect in a rectangle on the Stage . We start by setting its boundsRect : set FlakyRect's boundsRect to {100,100,200,200} Now suppose that we aren't satisfied with its present position, and would like to move it so that its location was {200,200} . We can say: set FlakyRect's boundsRect to {150,150,250,250} with justMoving Notice that the justMoving argument was specified. By doing this, we tell the system that the actor is not changing size, allowing the system to carry out a number of Page 95 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 s e t f r a m e s i z e o f A c t o r optimizations which let this handler perform slightly better. Notice also that in this example a moved event would be sent to FlakyRect . Next, we define the mousedown handler to shrink or expand our FlakyRect . We set the boundsRect relative to the current boundsRect to add or subtract a pixel from each side. on mouseDown of me (a FlakyRect) repeat while the mouse is down if optionKeyDown() then -- shrinking! set my boundsRect with relative to {1,1,-1,-1} else -- expanding! set my boundsRect with relative to {-1,-1,1,1} end if end repeat end mouseDown See Also minimumSize . setframesize of Actor setFrameSize me, h, v with physical Sets the frame size of the Actor to h and v. me (an Actor) h (a Number) v (a Number) [with physical] (a boolean): If True , h and v are assumed to be given in physical coordinates. setlocation of Actor setLocation me, x, y with relative with physical Changes the actor's boundsRect so that its center is the point {x,y} . event is send to the actor and other optimizations may be made. SetLocation calls setBoundsRect with justMoving set to True so that a moved Note: Since the location is a virtual property, computed from the actor's boundsRect , a change in boundsRect might change the location without calling setLocation . Thus, if you want to catch any change of location of you actor, you should redefine setBoundsRect .x Page 96 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 s e t o r i g i n o f A c t o r me (an Actor) x (a Number) y (a Number) [with relative] (a boolean): If relative is True , the current location is offseted by x and y. [with physical] (a boolean): If True , it is assumed that x and y are in physical coordinates. See Also setBoundsRect and location . setorigin of Actor setOrigin me, xorigin, yorigin with forceredraw Moves the point in the local coordinate system of the actor specified by {xOrigin,yOrigin} to the topLeft of the actor's boundsRect . As a result, the entire contents of the actor pans to accommodate the new origin. Note: If the forceRedraw argument is False the system optimizes the operation making it considerably faster. There are a number of circumstances, however, in which this optimization results in draw errors. In particular, the actor to be panned should not be covered in any part by any actors in its window, and it should have no text. Also the actor (or anything in it) may not be rendered with renderers that do not render masks uniformly (like an imageRenderer that paints a PICT as opposed to something like Red ). In general, a redraw error when panning is a clear indication that you cannot use this optimization and thus should call this handler with the forceRedraw argument set to true .x me (an Actor) xorigin (a Number) yorigin (a Number) [with forceredraw] (a boolean): If True (the default) , everything in the actor is redrawn. Example Setting the origin property effectively moves the specified point to the upper-left corner of the container. As a result, actors inside the container will pan vertically and/or horizontally to fit within the new coordinate system. For example, setting the origin of a container (whose origin is currently set to {0,0} ) to {-5, 5} will move all contained actors 5 logical units to the right and five vertical units up. Until the origin is again Page 97 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 s e t s c a l e o f A c t o r changed, the point at the actor's boundsRect 's upper-left corner would have a value of {-5,5} . See Also set hOrigin , set vOrigin . setscale of Actor Sets the actor's scale . The default scale is {1,1} . A scale of 1 means that if the logical width of an actor in the Actor's contents equals 100, that actor is 100 pixels wide. Setting the scale to 2 doubles the number of pixels required per logical unit (the actor would be 200 pixels wide). me (an Actor) xscale: A positive number. yscale: A positive number. setScale me, xscale, yscale See Also set hScale and set vScale . setsize of Actor setSize me, h, v with physical with relative Sets the Actor's width and height to h and v respectively. Note: If the one of the components of the new size is odd and physical is True , it is not guaranteed that the actor will keep its physical location constant. The physical size, however, will be the exact size specified.x me (an Actor) h (a Number) v (a Number) [with physical] (a boolean): If True , h and v are assumed to be given in Stage coordinates. [with relative] (a boolean): If True , h and v are added to the current width and height to compute the new size . SetBoundsRect is called to do the work. If the size specified is smaller than the minimumSize , the size is set to the minimumSize . Page 98 Draft.

Note that the actor is considered shown if any part of its boundsRect is shown. Note: This is not the same as the visible property, since an actor's visible could be True but the actor could be covered by other actors or be clipped out by some container.x me (an Actor) Example We might want to implement an egocentric actor that always wants to be visible. This actor will start complaining, by beeping, as soon as it ceases to be visible. It uses the shown property to check whether it is still showing. Let us call this actor Narcissus .

It searches the contents of its container for the next actor whose autotab property is set to True . If direction is 'forward' we search from the current keyTarget to the bottom layer. Otherwise we search up. The search wraps if nothing is found. If an actor other than itself is found, the keyTarget of its window is set to it. me (an Actor) [with direction]: 'forward' or 'backward' . Example Consider a window with several autotab actors in it. Elroy and Jake are two of these actors. They are on a mission from God : to keep the keyTarget to themselves. Clearly, the tabToNextActor handler needs to be redefined as follows. on tabToNextActor of me (an Elroy) with direction set the keyTarget of my window to Jake end tabToNextActor on tabToNextActor of me (a Jake) with direction set the keyTarget of my window to Elroy end tabToNextActor Notice that as soon as Jake or Elroy become the keyTarget , they will keep alternating as keyTargets until the user desists of using the tab key to reach other actors.

This property is set automatically by the tick handler of this clock object. This will always be an integer from 1 to the length of the list in the animatedCursor's media . Note: In the case of animatedCursors there is a distinction between the cursor of the Stage and the cursor that is actually showing at the moment.

AppleEvent (an Object) See _Inside Macintosh_ for information about AppleEvents and how they work. SK8 has objects that can be used to implement AppleEvent send and receive operations. An AppleEvent object has the following virtual properties: Target An AETarget object. an eventClass The catagory of command, an OstypeString. an eventID The id of the command, an OstypeString. For low-level implementation reasons, any AppleEvent object needs all these so they are all required to be specified when the AppleEvent is created. Example: new AppleEvent¬ with target HyperCardTarget¬ with eventClass "misc"¬ with eventID "eval" The eventClass and eventID together encode a command and are specific to the application.

BevelRenderer (a Renderer) The BevelRenderer is designed to create a bevel effect using the frame of a rectangle. It is particularly suited as a frameColor renderer. The net effect is to bevel the frame area of an actor, giving it a 3D appearance. The prototype BevelRenderer renders a grayish area. You may change the renderer used to color to bottom, left, right and top parts of the actor's area by setting the bottomRenderer, leftRenderer, rightRenderer and topRenderer properties, respectively, to the renderer you wish. Note: Bevel renderers are used to add "3-dimensional" shadowing around the sub-panels in Sk8 windows. To see the effect, set the framecolor property of a rectanglular actor to a bevel renderer, and the framesize (the width of the frame) to {1,1} or {2,2} or even larger.x See Also bottomRenderer, leftRenderer, rightRenderer and topRenderer.

This object is designed to be added as a parent to other objects in order to provide the standard browsing component functionality. There are two main pieces of functionality. First, it will cause an actor to highlight itself when it is the keytarget of a piece of browserpaper. Second, it will define a MenuPrototype handler on the object (described in detail in browserMenuBar ). Page 129 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 t a r g e t p r o j e c t o f B r o w s e r C o m p o n e n t The following conventions are used in all the existing browser components. Please follow these conventions when making your own components. First, the standard API to a component is defined by it's properties. There are one or more "input" properties which define the set of constructs that the component operates on. For example, the PropertyPicker has a property 'inputobjects' takes a list of objects and displays their shared properties. In general, all components which deal with objects should deal with single or multiple object input allowing multiple object editing. Components generally have one or more output properties which will output the viewed information or some subset of the viewed information (say the selected item(s)). For example, the PropertyPicker has a property 'outputproperty'. This is the currently selected property. Note that the property list also has a property 'outputObjects' which always outputs the current 'inputObjects'. The reason for this is that it is a good idea to have each component output all the information another cooperating component would need to work with it. For example, a property list is generally wired to some kind of property value editor. Such an editor needs to know both the property name as well as the set of objects in which this property is being edited. Another convention followed in Browser Components generally is the editing property. This property can be set to True or False , and acts like a safety mechanism. When it is set to False , it should shut off the editing capabilities of the component. That means that no changes should be made to the constructs being viewed. Another good thing to do when building components is to try to point to the minimum set of objects, and to let go of objects as soon as possible. This is so that your browser does not hold on to a user's objects that should be getting garbage collected. See Also See the functions: BrowserHighlight() and BrowserUnhighlight() Properties of BrowserComponent targetproject of BrowserComponent This property tells the BrowserComponent which project to focus on. In particular, if the user types in a SK8Script command or expression into a component (e.g. a QueryField ) then that script is evaluated in the workspace specified by the targetProject.

The clipboard can also be used as a temporary repository of objects. Objects usually get into the clipboard as a result of a copySelectionToClipboard or a pasteClipboardToSelection operation.

The two required arguments specify the type of thing we want to get out of the clipboard and the project into which to bring new things (since many times the clipboard will return new instances of objects). This handler is very versatile allowing you to do a variety of things to the objects in the clipboard. me (a clipBoard) thing: A SK8 object specifying the type of object we want to get from the clipboard. inproject (a Project): This is the object into which objects will be created as the result of paste operations. [with copy]: If True , the handler returns copies of the items found in the clipboard. Otherwise, the actual items in the clipboard are returned. If a copy needs to be made, it is made in the project specified. Defaults to True . [with removal]: If True , objects found in the clipboard are removed from it before the handler returns. Defaults to False . [with everyone]: If True , this handler will return everything in the clipboard that inherits from the specified type. Otherwise it will return the first item it finds. Defaults to False . objectsinclipboard of ClipBoard objectsInClipBoard me What this handler returns depends on the value of the incomingData property. If incomingData is False , the objectsOnHold is returned. Otherwise it means that something went into the system's scrap before we returned to SK8 from outside. When this happens, the clipboard looks at the scrap to see what objects are available. What this handler will then return is a list of the objects that could potentially be created from what is available on the scrap. This list is computed by asking the clipboard for the importTranslatorsApplicable and listing the finalObject of each one. me (a clipBoard) See Also objectsInClipboard for an extensive example illustrating this subtlety.

Example Let us explain the note above with a simple example. Consider a state of SK8 in which the objectsOnHold of the SK8Clipboard contains Julio (a Rectangle) and ZoomUpSound (a Sound). First of all, notice that in this case the objectsOnHold and the objectsInClipboard return the same thing: get the objectsOnHold of the SK8Clipboard {Julio, ZoomUpSound} {Julio, ZoomUpSound} get the objectsInClipboard of the SK8Clipboard Now notice what typesInClipboard returns. {Rectangle, Sound} get the typesInClipboard of the SK8Clipboard Now suppose we leave SK8 and paste a "PICT" into the clipboard.

All objects derived from Clock have the following characteristics: Clocks define a local time that is started at the startTime and ends at the endTime . Each time the clock ticks its currentTime is incremented by the timePerTick . By setting the masterOffset property we can specify at which time value in the master 's local time frame we want this slave to start running. The master property and the slaves property. These properties implement the clock hierarchy. The root of the hierarchy is the SystemClock which is ticked as fast as the system can allow. In order to be ticking, a clock has to be in the clock hierarchy which means that if we followed the master relation upwards we would hit the SystemClock . Start and stop can be used to start and stop the clock. It is important to note that a clock without a master will never tick . See Also master, slaves , tick , running , start , stop . Properties of Clock currentTime of Clock This property specifies the current time of the clock in its local time frame. It is usually set automatically by the tick handler. Getter get the currentTime of me me (a Clock) Setter set the currenttime of me to NewValue Page 149 Draft.

Getter get the endTime of me me (a Clock) Setter set the endtime of me to NewValue me (a Clock) newValue: The end of the clock's local time frame as a Number or False to indicate that this clock should never stop running. See Also startTime , running . master of Clock Specifies the clock that is one level up from this clock in the clock hierarchy. Whenever the master ticks it checks whether the required conditions are satisfied to start (or stop ) this clock. Getter get the master of me me (a Clock) Page 150 Draft.

See Also slaves . masterOffset of Clock Specifies the time in the local time frame of the clock's master at which the clock should start ticking. At that point its currentTime is set to its startTime and from then on gets incremented by the timePerTick until the endTime is reached at which point the clock stops ticking. Getter get the masterOffset of me me (a Clock) Setter set the masteroffset of me to NewValue me (a Clock) to (a Number) running of Clock Specifies whether this clock has been started but has not been stoped (it is running).

All this means is that all the masters of this clock will be started which does not guarantee that the clock itself will start ticking. The clock will only start ticking when its master 's currentTime is greater than the clock's masterOffset . Then again, its master will not start ticking until the same condition is fulfilled with its master. Finally, your clock will not tick unless its final master is the SystemClock . me (a Clock) to (a boolean) See Also start , stop which are shorthands for the set running handler. slaves of Clock This property stores a list of clocks that depend on this clock for being ticked.

The result will be False if and only if the collection is empty. The collection protocol centers on the notion of a “state” object for an iteration. Each type of collection chooses its own most appropriate representation for its state, and only the handlers of the collection protocol are affected by this choice. For all collections, however, a state of False is used to indicate that the iteration has completed, i.e. that it has passed over the final item in the collection. The representation for a collection's state is generally chosen to maximize efficiency of access to the corresponding item, and efficiency of computation of the following state. A vector, for example, might use an integer offset as its state, whereas a linked-list would be better off using a list-cell as its state.

A pseudo-typed collection is a collection for which “type-filtering” behaves differently than the simple default type-filtering, which selects items from a collection only if they descend from a given type. In other words a collection C is pseudo-typed if, for some type SomeType and some index N, “SomeType N of C” cannot simply be interpreted as “the (N)th item that is a SomeType in C”. Descendants of Text, for example, are pseudo-typed (consider that “word 1 of "Good morning"” cannot simply be interpreted as “the 1st item that is a word in "Good morning"”).x me (a Collection) type See Also initialState (for a discussion of collection iteration states), finalState, finalStateTyped, nextState, nextStateTyped, nthPreviousState, nthPreviousStateTyped insertAfterCurrentItem of Collection insertAfterCurrentItem me, state, newitem, dependentStates Note: An object intending to support the Collection Protocol must implement this handler.x me (a Collection) state newItem [dependentStates] See Also initialState (for a discussion of collection iteration states), insertInto , insertBeforeCurrentItem insertBeforeCurrentItem of Collection insertBeforeCurrentItem me, state, newitem, dependentStates Note: An object intending to support the Collection Protocol must implement this handler.x Page 164 Draft.

Whenever it's items are set and whenever the colorPicker is resized , a new number of rows and columns is computed to optimally show all of the colors. That is, it computes the appropriate number of rows and columns, based on the current size, to maintain a square shape for each of the cells. Note that the colorPicker cannot be scrolled in the usual manner, as it always makes all of it's items visible at all times. Note also that every item of a colorPicker must be a Renderer. Example The following SK8Script can be used to generate a simple palette of the default RGBColors: new colorPicker with ObjectName "BasicPalette" set the container of the BasicPalette to the stage set the boundsrect of the BasicPalette to {30, 30, 150, 100} set the items of the basicPalette to every item whose project = sk8 in the knownchildren of rgbcolor Note we make sure to choose only colors in SK8 as there may be an RGBColor defined in another project (such as the RGBColors defined in the ProjectBuilder project).

Complex numbers consist of a real part (with a real magnitude) and an imaginary part (also with a real magnitude). Complex numbers can be created with the function complex , and their real part and imaginary part can be examined with the functions realPart and imagPart , respectively. See Also the function complex , realPart , imagPart ComplexGradient (a Gradient) ComplexGradients are gradients with additional properties to let you control the penMode to be used when rendering and a start and end OpColor. At each rendering step the Opcolor will be incremented from the start OpColor to the end OpColor resulting in different degrees of the effect specified with the penMode . Example Consider the BlueBlend renderer. Here are the settings for each of the properties that are new to the complexGradient: penmode = 32 startopred = 65535 startopgreen = 65535 startopblue = 65535 endopred = 0 endopgreen = 0 endopblue = 0 The penmode 32 is the 'blend' mode. Note that the start Opcolor has the maximum values for the RGB components. Since the opColor controls the degree with which to apply the effect, this means that at the start of rendering this renderer is fully translucent. As we progress towards the end of the rendering, the renderer becomes less and less translucent until it is opaque. This renderer is called BlueBlend because start color and end color are Blue. Thus, at the start it blends blue with the background. Then it blends less and less becoming opaque Blue at the end.

It also sets the OpColor to the RGB specified in the startOpRed , startOpGreen and startOpBlue properties. This determines the degree with which the effect specified with the penMode will be applied. The rendering then proceeds in bands (just like in the Gradient renderers). At each step we increment the color to eventually reach the RGB specified in the endRed , endBlue and endGreen properties and at the same time we increment the OpColor to reach the RGB specified in the endOpRed , endOpGreen and endOpBlue properties.

Each condition response object must define an invokable handler, an invoke handler and, optionally, a writeObject handler. The invokable handler must return True if this response is currently invokable, and False otherwise. The default handler always returns True . The invoke handler performs the response action. Generally, this handler will either “recover” from the condition, “abort” from it, or enter some kind of interactive mode for allowing the user a choice of ways of recovering or aborting from the condition. The writeObject handler for a ConditionResponse , when its rereadably argument is False , should write the following information about the response. If the response is invokable, it should write a description of exactly what this response will do when invoked (typically, phrased as a question, as in “Would you like me to try to find the missing object on the disk?”). If the response is not invokable, the writeObject handler should write an explanation of why it is not. Note: The invokable , invoke and writeObject handlers may examine the function currentCondition , which will return the condition object of the current condition being signalled.x Note that SK8 will never call invoke in response to a particular condition without first having called the response object's invokable handler and gotten True as its value. Thus any implementation of the invoke handler may assume its response object is currently invokable. Consequently, you should be sure never to directly call a response object's invoke handler without first verifying that its invokable handler returns True immediately before. See Also invokable , invoke , conditionResponses of Project , the Condition System section of the User Guide's SK8Script Language chapter Handlers of ConditionResponse invokable of ConditionResponse invokable me Returns True if this response is currently invokeable, and False otherwise. The default handler (i.e. the one defined for ConditionResponse ) always returns True .

Connectors are useful whenever you want a LineSegment to automatically maintain a connection between actors. Connectors are automatically created by calling the Actor connect handler. Connectors attach to actors in various ways, which are controled by the startGeometry and endGeometry properties. The valid options are 'center' , 'projectCenter' , 'horizontalEdge' , 'verticalEdge' and 'closestEdge' . The connections created with connectors are directional: you specify a startActor and an endActor. Thus, you can ask an actor what is connected to and what it is connected from. You can also ignore the direction by asking the actor for all the actors connected to it in any direction. See Also The connector properties: startActor, endActor, startGeometry and endGeometry and the Actor handlers: connect , connectors , connectedActors , connectedTo and connectedFrom . Page 193 Draft.

DataObject (an Object) Since many times users will be representing raw data in the form of objects, this object exists simply as a way of deepening the hierarchy. That is, such data objects will be children of this rather than of object itself. This makes it so that while browsing the hierarchy isn't cluttered. It has no other meaning. DateTime (an Object) DateTime supports the convenient storage and type coercion of calendar dates and times. For example, the DateTime object can coerce a text string such as "September 21, 1968", "21 sept 68", "9/21/68", or "12:07 pm" into a value which can be compared to other dates. DateTime object uses storage similar to the Macintosh's, counting the seconds since January 1, 1904. DateTime and its children may be coerced into strings (text) or integers (numbers) by using classic SK8Script coercion. For example, DateTime as a string returns "October 5, 1994" Page 198 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 d a t e S t r i n g o f D a t e Ti m e Now as a number returns 2864201917 (the seconds since 1904) DateTime and its children may be compared with predicates such as = ,<> , < ,> , etc. "A<B" means A is before B; i.e., less than is defined as coming before. Example mybirthday \< Now returns True Properties of DateTime dateString of DateTime The dateString handler lets you get the string representation of the date, or to set the date based on a string. Note that the value returned by a getter may not be the same exact value to which the property was set. For example, after setting a DateTime 's datesting to "4 jun 1993", getting the DateTime's datestring would return "June 4, 1993". Getter get the datestring of me with numericform with abbreviation with dayofweek If numericForm is True , a numeric string is returned, for example, "9/21/68".

For descendants of DateTime , the default value is copied from the new object's parent; if the parent is DateTime then the default value is the number of seconds between 1904 and midnight of the day the new DateTime object was made.

It provides a "Close" menu item that closes the active window and a "Quit" menu item which quits SK8. FileName (an Object) The FileName object is used to represent the location of a file or a directory (whether the file actually exists or not). A simple String could represent a file or directory location, but the FileName object has an understanding of logical and physical names, directories and other parts of a file name and so forth, independent of operating system specifics and syntax. A fileName object has these virtual properties. Each can be accessed or set individually. storageDevice directory name type The device the file is stored on. A string describing the File's directory. File's name within that directory, a string. The File's type, a string. (MacOS specific) (MacOS specific) macFileType macFileCreator There are two ways a File object can be be specified; physically or logically. A File object set with a physicalName refers to the location of the file explicitly. For instance, this is a physicalname: Barney:myDirectory:mySubDirectory:name.text Logicalnames use the physicalName of a DirectoryNickname object at the top level, with a semicolon to note that this is a Logicalname. For instance: SK8;SubDirectory:SubSubDirectory:name.text Children of the File object allow writing to and reading from the disk. File objects have properties that allow disk access of resource forks, folders, and data forks. Since Files and Streams are collections, all of their operations are available via path expressions. Read and write operations are supported in ByteStreams and TextStreams via the collection protocol. This allows one to read or write to a file from within a repeat loop or by using a complex path expression. See Also File (a FileName object) Page 280 Draft.

You are guaranteed a Sk8 object for each font that you have installed in your System Folder. When SK8 is restored, all fonts that were present in the original environment and are not present in the current one turn into Chicago. Fonts that are available now that were not available in the original environment are created on the spot. Thus, if you ask for the fonts of the system you get the knownChildren of font. Fonts are named like their fonts when possible. Exceptions occur with Times which is called "TimesFont" because "times" is a reserved word in SK8Script. Note also that fonts that start their names with a number will be appended an "f" at the start. Thus a font called "1Times" would become an object called "f1Times".

When you use foreign (native operating system) memory, the SK8 memory system can do very little management or safety checking for you. Using foreign memory is for very advanced users only. Please read the SK8 User Guide chapter "SK8 Foreign Function and Data Interface" before atempting to use foreign memory as inappropriate use can easily crash your machine. ForeignMemory may be "owned" or "unowned" by SK8. When foreignMemory is owned by SK8 and is no longer referenced, its deallocation handle, disposeMem, is invoked on it. By default memory allocated via newMemHandle or newMemPointer is owned by SK8. Memory ownership can be changed by functions memOwn and memDisown. When foreignMemory is not owned by SK8, the user must explicitly deallocate it by calling foreign routines where defined (e.g. Macintosh Traps such as DisposePointer, DisposeHandle, DisposeWindow, etc.). These functions may be invoked multiple times on the same foreignMemory object without error. When SK8 owned foreignMemory objects are passed Page 285 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 w r i t e o b j e c t o f F o r e i g n D e f Tr a p to disposeMem, the disposeMem handler for that type of memory is invoked. IF UNOWNED FOREIGN MEMORY IS PASSED TO DISPOSEMEM NO ACTION OCCURS. You are not warned about this. If you disown foreign memory, you are taking full responsibility for it. Sometimes raw machine addresses or handles are passed back to SK8 as a result of foreign function calls. As SK8 has no knowledge of such foreign entities, it can do no management or error checking. One can make SK8 aware of them by explicitly telling SK8 what their storage "type" is. Note that SK8 trusts what you tell it. If you lie to SK8, you can easily crash you machine. (This is technically known as "bad karma"). You give SK8 information about a raw machine pointer or handle using the function toMemHandle or toMemPointer. When you do this, you should drop any references the the raw machine datum and use the memPointer or memHandle returned by the function you called to tell SK8 about it. When a foreignMemory object is created, its contents are set to the value zero (0). You can add initialization by defining a handler on the memory "type" via the handle initializeMem. You can define cleanup actions via the handle disposeMem. Note that the disposeMem handle replaces the default cleanup, so you must remember to either call the foreign deallocator (e.g. DisposeHandle, DIsposePointer, or whatever you have defined) or be sure to "call next method" so that the default default deallocator is invoked. Use disposeMem to dispose interior pointers or use non-default deallocators (e.g. DisposeWindow for a handle created by a call to NewWindow). See Also newMemHandle , newMemPointer, disposeMem , memOwn , memDisown , toMemPointer, toMemHandle , toSK8Mem , initializeMem , disposeMem , MemPointer, memHandle Function (an Object) A Function is similar to a handler, in that it is a body of SK8Script commands that may be executed, but it is different in that it is not associated with any particular object , rather it is associated with its project . As opposed to a handler, a function (1) does not require any arguments, and (2) does not have the variables me and myself bound in the body of the script. Example A simple function might be defined like this (note that there is no object type information for n): on add2 of n return n + 2 end add2 of n To see all of the functions which are defined in SK8, use this command: get the functions of sk8 Page 286 Draft.

The behavior of objects and operations on objects are performed by handlers. A Handler is a named piece of code that is executed in response to a message or event. Handlers are procedures available to an object taht specify some action to be performed. Handlers are inherited just like properties. An object inherits all the handlers defined on each of its ancestors. You can't really do a whole lot with the actual handler class. More important are its descendants, which are handlers for objects. The handlers of an object may be found by useing a handler called handler. See Also Function HandlerDataRect (a Rectangle) This rectangle along with the ObjectDataRect and the PropertyDataRect are the objects used to provide drag and drop functionality between the various components. This one provides a place to drag a single handler which has been defined on one or more objects.

Confidential. ©1995 Apple Computer, Inc. 5/8/95 s e t u p t e x t c o l o r s o f I c o n Te x t P i c k e r ImageRenderer (a Renderer) The ImageRenderer is in charge of rendering anything that has image media associated to it. The ImageRenderer can thus render PICTs, cicns, ppats, PATs and pixelMaps. Through the renderStyle property, the ImageRenderer lets you specify three ways to paint the image associated to it: (1) stretch it to fill a region. (2) tile it to fill a region. (3) do not tile or stretch: just show it at its natural size within the region. The ImageRenderer lets you do all this regardless of the type of media you are using with it. Note: The ImageRenderer 's media can be any descendant of Media that has the following three handlers defined: renderStretched , renderTiled and renderUnstretched . In a fresh SK8 these are any descendants of QDPicture , PixelMap , BWPattern , ColorPattern and iconRSRC .x Since it might be the case that an ImageRenderer's image is irregularly shaped and does not fill the whole area to be rendered, the ImageRenderer first paints the backGroundRenderer into the region to be drawn. On top of that, the imageRenderer's image (from its media ) is painted. Note: if the media of your imageRenderer does cover all the area given to it to render, it is a good idea to set the backGroundRenderer to False . This saves a whole rendering step, making your renderer substantially faster.x The final property worth mentioning at this juncture of the narrative is the translucentColor property. With this property you can specify an RGBColor that should be treated as transparent. Thus, if you set this property to Red , every pixel in your renderer's image that is red will be transparent, showing what lies behind the actor being rendered with your renderer. Example Suppose you are writing a chess program. Your first task is to draw the board. Let "Board" be the rectangle you have created for this purpose. The board can be rendered easily with a simple black and white pattern if you think of it as a blown up pattern. So we will find the appropriate pattern and stretch it to fill our board. First we make the renderer. Then we associate it to the right media and set the board's fillcolor to the renderer. new imageRenderer with objectname "boardRenderer" set boardRenderer's media to GrayPattern set board's fillcolor to the boardRenderer You will notice that the board just looks like a gray matt all over which is not what we wanted. The problem is that the renderStyle of an ImageRender that renders a pattern defaults to 'renderTiled' which makes sense for patterns. We want our pattern to be stretched. Therefore we just set boardRenderer's renderStyle to 'renderStretched' Page 324 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 b a c k g r o u n d r e n d e r e r o f I m a g e R e n d e r e r And we tell the board to redraw itself to show the change. (Note that the change does not happen automatically because a renderer has no way of knowing all the actors it is rendering). lightForceRedraw board And that's it. If are in an exploratory mood you can try setting the renderStyle to 'renderUnstretched' and see the pattern in all its original glory. (Doing this, by the way is a simple way of finding out how big a pattern is). See Also media , renderStyle , backgroundRenderer and translucentColor. Properties of ImageRenderer backgroundrenderer of ImageRenderer The renderer to use to render the background (behind the media). If False no rendering of the background is done. Note: If your media is guaranteed to coved all the region it is to render, the backGroundRenderer should be False . This will make the rendering a lot faster.x Note: setting this property to a translucent renderer might change the state of this renderer so that its translucent handler now returns True . When this happens it is important to inform every actor that is being rendered by this renderer of the changes. You do this by setting the fillColor (or frameColor ) of the affected actors to this renderer again. Failure to do this might result in draw errors.x Getter get the backgroundRenderer of me me (an ImageRenderer) Setter set the backgroundrenderer of me to NewValue me (an ImageRenderer) to: A Renderer or False, to indicate that no rendering of the background is necessary.

Defaults to 0, meaning that the image will be lined up with the left edge of the mask being rendered. This property is only visible when the renderStyle is 'renderUnstretched' .

Getter get the Media of me me (an ImageRenderer) Setter set the media of me to NewValue Sets the media the ImageRenderer uses to render an arbitrary region. If set to False , uses the ErrorColor to render itself. Note: If the new media's type differs from the old media's type, the renderStyle of the renderer will be changed to be the defaultRenderStyle of the new media. For example, if the old media was an IconRSRC , the renderStyle was set to Page 326 Draft.

Can also be set to False . See Also renderStyle , and defaultRenderStyle of Media . renderstyle of ImageRenderer This property determines what the renderer does with the media. Possible values for it are: 'renderStretched' : the image is stretched to fill the region. 'renderTiled' : the image is tiled to fill the region. 'renderUnstretched' : the image is rendered with its natural size using the hOffset and vOffset properties to determine their position. Note: For the change to take effect in an actor being rendered with the renderer in question you have to force the actor to redraw itself. You can do this by calling lightForceRedraw.x Getter get the renderStyle of me me (an ImageRenderer) Setter set the renderstyle of me to NewValue me (an ImageRenderer) to: One of 'renderStretched' , 'renderTiled' and 'renderUnstretched' . See Also hOffset , vOffset , lightForceRedraw of Actor and ImageRenderer for an example of the use of this property. Page 327 Draft.

Thus, if you set this property to Red , every pixel in your renderer's image that is red will be transparent, showing what lies behind the actor being rendered with your renderer. Note: using this property is significantly more expensive than not using it. Do not use it when it is not required.x Note: setting this property to an RGBColor when it was previously False might change the state of this renderer so that its translucent handler now returns True . When this happens it is important to inform every actor that is being rendered by this renderer of the changes. You do this by setting the fillColor (or frameColor ) of the affected actors to this renderer again. Failure to do this might result in draw errors.x Getter get the translucentColor of me me (an ImageRenderer) Setter set the translucentcolor of me to NewValue me (an ImageRenderer) to: An RGBColor or False , to signify that this effect is not wanted. voffset of ImageRenderer Specifies the number of pixels to offset the image when rendering.

See Also hOffset , renderStyle . Handlers of ImageRenderer capturepicture of ImageRenderer capturePicture me, otheractor with size The capturePicture handler takes a snapshot of an actor or a renderer and places it in an imageRenderer. You can specify the size you want the cached pixmap to have. This is very important since the size of the cached pixmap determines the amount of memory the imageRenderer will use. Consider an actor called "act" whose size is 400 by 600 pixels. You want to capture its picture to render a rectangle whose size is 50 x 50. Assume you have snp, an imageRenderer you created. Then the simplest thing is to just call CapturePicture as follows: Note that no size is provided. The system assumes you want to cache act's image in all its glory and thus allocates a pixmap of act's size. The memory required for it is therefore 400 x 600 x depth/8 Assuming 256 colors (8 bit color), we get 240000 bytes = 240K This is a clear waste if we are only going to be using our renderer to render the small (50 x 50) rectangle. We should instead do the following: capturePicture snp, act with size {50,50} capturePicture snp, act This will allocate a pixmap of the right size and the memory usage will be 50 x 50 x 1 = 2500 = 2.5K !!! Need we say more? Note: If otherActor is a renderer the size argument is required.x Page 329 Draft.

Now we render an actor's fill with msb. set myActor's fillcolor to msb The capturePicture handler is used to make the snap shot.

Note: Not implemented in 1.0a2x me (a Keyboard) Example get keysDown of the Keyboard Label (a Rectangle) The Label displays a single line of text, which is non-editable. Labels are useful for showing short, read-only text strings. The Label is a child rectangle, with three main differences: (1) the default framesize of label is {0,0} (the frame is not visible). (2) the label's fillcolor is Transparent and thus, only the text is visible. (3) when the label's text is set, the label's width grows or shrinks so that it is large enough to display all of its text. The Label's size changes whenever you change its text , its textFont , its textHOffset , its textVOffset , its textSize or its textStyle . You can control in which direction the label resizes with the textLocation property. If the textLocation is, for example, 'centerLeft' then the label will grow or shrink to the right and the text's start will not move. If the textLocation is 'centerRight' , the label will resize to the left, keeping the end of the text in the same location. Page 347 Draft.

It must be instantiated as another object, with its own cellSet, such as the MacBarberPole or MacRoundIndicator. Every MacAnimation has a property cellSet which contains a list of renderers in the order of frames in the animation. Also associated with each MacAnimation is a Clock , and, when the clock is started, the MacAnimation will begin to change its renderers in the order that they appear in its cellSet property. The rate of the animation can be set through the set rate handler, and the actual animation can be started and stopped using startAnimation and stopAnimation . This object is the parent class for the Macintosh Look & Feel Interface elements which are animated, namely the MacBarberPole and MacRoundIndicator.

In fact, the only real difference between it and SK8's version is the check color (in this case, black instead of red.) It is used to represent any binary choice. A MacCheckBox is a Label whose text is offseted to the right a sufficient number of pixels to leave space for the CheckBoxCheck : a rectangle with an “X” rendered inside. The MacCheckBox's mouseSensitivity is 'opaque' , thus clicking anywhere on it checks or unchecks it.

In other words, if the arrow is in a closed state (i.e. pointing to the right), and a user clicks on it, it highlights, animates to the open state (i.e. pointing down), and unhighlights. To find out which state the arrow is in, you should look at its state property. See Also MacWidgets Page 372 Draft.

A 'closed' state indicates that the arrow is currently pointing to the right (which in the Finder means that the folder is closed), while an 'open' state means that the arrow is pointing down. Getter get the state of me me (a MacFinderArrow) Setter set the state of me to NewValue me (a MacFinderArrow) to: One of 'closed' or 'open' .

Confidential. ©1995 Apple Computer, Inc. 5/8/95 m o u s e d o w n o f M a c F i n d e r A r r o w On receiving a mousedown event, a MacFinderArrow will make sure that, as long as the mouse button is down, that it will be highlighted while the cursor is over its active arrow, and unhighlighted when it is not. Once the user lets up on the mouse, if the cursor is no longer over the active region, the arrow puts itself back into an inactive state. If, however, the cursor is over the arrow, it will call its animate handler to change to the other possible state. me (a MacFinderArrow) MacMenuItem (a MenuItem) This object is a descendant of menuItem , specialized for use in a MacPopupMenu . It is specialized in that when it is selected, it changes the text of its menu to its own text, in the way that standard Macintosh popups work. Beyond that, however, it behaves in exactly the same way that a menuItem would. See Also MacPopupMenu , menu , menuitem MacModalDialog (a MacDialog) MacModalDialog is a direct child of MacDialog , and is the Macintosh standard dialog box, complete with "OK" and "Cancel" buttons. The only specialization of this object from its parent is that its windowStyle is set to 'doubleEdgeBox' . This, in turn, means that the user is not able to move the dialog, and the only available actions are to (1) press either button, or (2) go to another application via the Finder menu in the upper right hand corner of the screen.

The only specialization of this object from its parent is that its windowStyle is set to 'movableDialog' . This, in turn, means that, while the user can move the dialog box around the screen by dragging on its title bar, the only other available actions are (1) to press either button in the dialog, or (2) to switch to another application, via the Finder menu in the upper right hand corner of the screen. See Also MacWidget , MacDialog , MacModalDialog , MacAlertBox MacPopupMenu (a Rectangle, MacWidget) The MacPopupMenu object is a menu with 3 default items that has a text title, along with a SK8 menu object. The behaviors that have been added beyond those of a regular menu are that (1) the current menu selection always shows in the menu title (as opposed to the text title), and (2) when the user mouseDowns on the MacPopupMenu , the current selection is automatically checked. In order to affect the actual menu, you should use the MacPopupMenu 's menu property, which acts just like a SK8 Menu , except that when you add items to the menu, they should be descendants of the MacMenuItem object. MacProgressIndicator (a Rectangle, MacWidget) This is the definite progress indicator which you can find in the Finder dialog which appears when you copy files from one place to another. It is composed of a long, thin rectangle (horizontally oriented) that starts out as a blue color. As more of an action is completed, the rectangle starts changing to a gray color, from the left hand side, sort of like a thermometer rising. Page 375 Draft.

False means that you'd like it to change instantly. [with force]: Boolean. This was included as an option for internal use only--it is set to true if the indicator gets resized , so that the resized handler can call the set percentDone handler to have the update draw correctly.

MacRadioButton (a RadioButton, MacWidget) This object is EXACTLY like SK8's version, which is called RadioButton , and complies with the Macintosh Interface Guidlines. RadioButtons are a group of mutually exclusively selectable buttons: clicking on one button will unhilite the others. In SK8, RadioButtons are "clustered" together by putting them into a container. Once clustered, selecting one radio button will deselect all other buttons in the cluster (its container). A MacRadioButton is a Label whose text is offseted to the right a sufficient number of pixels to leave space for the RadioButtonButton : an oval with another oval inside of it. The MacRadioButton's mouseSensitivity is 'opaque' , thus clicking anywhere on it checks or unchecks it.

It looks like two curved arrows chasing each other in a circle, and is generally used to denote that something is happening over the network. See Also MacWidget , MacBarberPole , MacAnimation MacScrollBar (a Scroller, MacWidget) The MacScrollBar is exactly the same as a scrollbar that you'd find on the right hand side and along the bottom of many documents that you'd edit every day. It inherits much of its behavior from the scroller object, but behaves in a way consistent with the Macintosh Human Interface Guidelines. Any object in SK8 which uses a scroller may use a MacScrollBar in its place with no modification (except for actually switching them and making sure that the same ports are wired together). The space between the scroller's arrows represents the valid range, and the position of the thumb's top edge in it represents the selected value which we call the currentValue . The currentValue can be changed by dragging the thumb and clicking on the arrows or the body of the scroller. The most common use of scrollers is to allow the scrolling of text in EditText fields or the items of a picker. In this latter case, the range of the scroller is the number of items in the picker. To hook up the scroller and the picker, you just need to make sure that each time the currentValue of the scroller changes, the picker's verticalScroll property is set to it. This can be done using ports as illustrated in the partnerScroller property of Picker. Page 378 Draft.

Setting this property to false will cause all of the contents of the MacScrollBar to be hidden, thus making it a white rectangle surrounded by a black frame. Setter set the isactive of me to NewValue isEnabled of MacScrollBar This property should be set to true when the scrollee is, in fact, scrollable, and false if it is not. For example, in many text editors, if the total amount of text is less than is visible in one screenfull, the scrollers are disabled, since there is no need to be able to scroll through the document. When a scrollbar is disabled, the renderers for the arrows turns into an outline of an arrow, the body and thumb disappear, and the MacScrollbar no longer responds to any mouse clicks. Getter get the isenabled of me Setter set the isenabled of me to NewValue shadow of MacScrollBar This is just a transparent rectangle with a black frame that gets dragged around when the user drags the thumb of the MacScrollBar.

It consists of a rectangle which contains a MacScrollingListText, which is a picker (on the left) and a MacScrollBar on the right. You can set the items in the list by using the set items handler, and the rest of the protocol is the same as a SK8 picker, applied to the textList of the MacScrollingList . Example set the items of myScrollingList to the knownChildren of RGBColor See Also MacWidget , MacScrollBar, picker Properties of MacScrollingList items of MacScrollingList Specifies the items that the MacScrollingList displays. Note that what appears in the MacScrollingList is not the item itself but a textual representation of it. This representation is created by calling the createTextDisplayItem handler on each item. The default handler uses the objectString of each item. Page 380 Draft.

For different widgets, this means different things. For inactive buttons, for instance, the text (and outer frame for default buttons) should be grayed out and the button should not respond to mouse clicks. Getter get the isactive of me Setter set the isactive of me to NewValue Setting isActive to false will cause the textColor to go to GrayTone50 and change the mouseSensitivity to 'invisible' , while setting it to true will make the textColor black and make the mouseSensitivty 'normal' . mask (an Object) A mask represents an arbitrary area. Masks can be defined in a variety of ways and can then be combined with intersection, union and difference functions. Masks can be painted and framed. They are also used for clipping (restricting drawing to be visible within the mask only). Use masks in conjunction with pens to write your own renderers.

See Also newMemPointer, disposeMem , ForeignMemory Menu (a Rectangle, MenuCollection) A menu combines a SK8 actor with a Macintosh menu object. In the following discussion we refer to the later as the menu's pop up component. Menus in SK8 are versatile objects allowing you to place them both in the Macintosh menubar and in the contents of any actor. Menus change appearance depending on where they are. If they are installed in a menubar, they look like simple rectangles that pop up a menu when the mouse goes down on them. When a menu is on its own (attached to an actor) it looks like a pop up menu: it has a drop shadow and an inverted triangle (the menuArrow). A menu becomes useful by adding menu items to its menuItems property. You can build hierarchical menus by adding a descendant of Menu to the menuitems of a menu. Properties of Menu arrowcolor of Menu Specifies the fillcolor of the menu's menuArrow. The arrow is only visible when the menu is not part of a menubar and is attached to an actor. Page 391 Draft.

This usually happens when a mouseDown event occurs on a menuBar or a popUp menu, but you can call it anywhere in your code. Several options are provided to control the location and appearance of the menu. Notice that if neither the relativeActor nor the coordinates are provided, the menu will appear at {0,0} , that is, the topLeft corner of your main monitor. There are two ways of specifying where the menu will show up: you can provide the h and v coordinates or you can provide a relativeActor. If the relativeActor argument is not False , the menu comes up on the actor. You can control the exact location of the menu using the position argument. Four locations are predefined, corresponding to the four corners of the relativeActor's boundsRect. The fifth location, the 'mouseLoc', pops up the menu exactly where the pointer is. me (a Menu) [with h]: The horizontal position (in Stage coordinates) at which the menu will be poped up. Defaults to 0. [with v]: The vertical position (in Stage coordinates) at which the menu will be poped up. Defaults to 0. [with milliseconddelay]: If specified, the system waits the required number of miliseconds before poping up the menu. [with relativeactor]: If specified should be an actor on the Stage . The menu will be poped up in a position relative to this actor using the position argument. [with position]: How the menu will be placed in relation to its relative actor. Options are: 'topleft' , 'topright' , 'bottomLeft' , 'bottomRight' , 'mouseloc' and 'bottomRightAligned' . [with defaultmenuitem]: The menu item to be selected by default when the menu is poped up.

This involves arranging the menus within the menubar and pulling them down when the user presses mousedown on them. It's important to note that the rectangle is only visible when you install the menubar on an actor. The menus installed in the menubar are also contained by it. When the menubar is made the menubar of the Stage , the Macintosh menubar is used to display the menu and thus the rectangle is not visible.

This checkbox has three states. When it is checked , the property is set to True in all the objects the checkbox controls. When it is unchecked, the property is set to False in all the objects controlled. The third "gray" state restores the original values of that property for all the objects controlled. The original state is saved when the objects are associated to the checkbox. The stateProperty property tells the checkbox which boolean property of its objects it is controling. The objects affected are stored in the objects property. Example Consider a rectangle called "Julio" that has two other rectangles in it called "Pipo" and "Cacho". Now we create a new MultiObjectStateCheckbox and add it to Julio's contents . From there we let it control whether Pipo and Cacho are visible. Pipo and Cacho.

Object contains all the handlers needed to create new objects or copies of objects, initialize objects, add or remove properties, add or remove parents, assign object names, and more. If you create an object and you don't care who its parent should be, you should probably use Object as the parent. Note: Overriding the behavior of Object can have deep repercussions throughout the system. SK8 is happy to let you do that. To change the behavior of any handler of Object (or of any SK8 object), your should create a new child of the SK8 object into your project and shadow the SK8 handler for it.x Example The following statement creates an anonymous object and binds it to the variable x . One would not again be able to access this object unless it were bound to a variable (or to an object's property). set x to a new object If the object were not bound to x , then there would be no way for you to access the object. In that case, the object would be automatically trashed by the system. The SK8 garbage collector is responsible for ensuring that storage allocated for objects is regularly trashed: you need not take any explicit action to do so. The following is an example of creating a named object. The named object is automatically bound to the global constant MyNamedObject . How does this differ from creating an anonymous object (as in the first example) and then binding it to the variable MyNamedObject ? Only in that when one creates a named object, MyNamedObject is a constant instead of a variable. This means that you cannot accidentally re-bind MyNamedObject to anything else, unless you unname or rename the object via the objectName property. new object with objectName "MyNamedObject" An object always exists in one and only one project. To refer to a named object in a within a project, one need only specify the name of the object: get MyNamedObject's fillColor If one wants to refer to a named object in another project, one must explicitly specify the project name. For example, to explicitly refer to the object MyNamedObject which resides in the project MyWidgets , one uses the following expression: get the fillColor of MyNamedObject (in project MyWidgets) Page 465 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 d o n t S a v e o f O b j e c t However, this is not very modular because you may accidentally access an object in a project that may not later exist. SK8 facilitates modular access to information between projects such that, in this case, if MyNamedObject were to have been created in a superproject of the project in which it exists, it would be directly accessible to its subproject(s). Objects are created in the project in which the object creation code was compiled. To explicitly specify the project in which an object should be created, use the project keyword argument. For example, to create MyNamedObject in project MyProject : new object with objectName "MyNamedObject" with project MyProject See Also knownChildren , parents , baseParent , objectName . Properties of Object dontSave of Object If an object is never to be saved in a project or preserved to a standalone application, it should provide this handler returning True dontSave of Object returns False .

The objectName is a case-sensitive string which will serve as the name of the object. If you want to unname an already named object, then set its objectName to False . Naming an object is the most direct and fastest way you can access an object within your project. The objectName uniquely identifies the object within a SK8 project. The object's name becomes accessible to all subprojects so that it is not possible to have two objects with the same name in projects that require each other. Any SK8 object, except for a collection, can have an objectName . An object without an object name is called an anonymous or unnamed object. Note: You cannot change the name of a Project in SK8 1.0.x Getter get the objectName of me me (an Object) Setter set the objectname of me with force to NewValue me (an Object) to (a String): The new name for the object. Passing False makes the object become anonymous. Example This example shows how you can create an unnamed object and then name it.: set x to a new object set x's objectname to "MyNewObject" The following statement shows you how you can do the same thing in one line. new object with objectName "MyNewObject" See Also new, copy.

The base parent is retrieved it by using the baseParent handler. Getter get the parents of me me (an Object) Setter set the parents of me to NewValue The setter calls changeParents to do the work. me (an Object) parents: Should be a list of parents to replace the current parents of the object. See Also knownChildren , baseParent and changeParents . private of Object The private property marks a property or an object as either private or public. A private property or object is one which should not normally be directly accessed by subprojects of the project of the object for which the property has been defined. One can make a property or object private or cease it from being private at any time. Browsers and other user interface viewers may use the fact that a property or object is private in order to restrict its appearance in appropiate contexts. An object or property's "privacy" is enforced only by user interfaces or by other users, but not by SK8. In particular, it is enforced by the SK8 Project Builder. Getter get the private of me with property Page 469 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 p r o p e r t i e s o f O b j e c t Private can be used to find out whether an object or an object's property is private or not. If one does not provide the property argument, then private returns True if the object is itself private; otherwise it returns False . me (an [[Object]]): The target object. [with property] (a [[Symbol]]): This symbol represents the name of a property. Setter set the private of me with property to NewValue One can either make the object or one of its properties private by letting to be True and public by letting to be False . me (an [[Object]]): The target object.

You should always call the inherited initialize handler within your initialize before you do you own special initialization. You should use initialize rather than new or copy to define special initialization behavior for your objects. The initialize handler for Object does nothing. new and copy call initialize on the child or copy that they create after memory has been allocated for it and its properties have been initialized. Note: The internal structure of the initarg object passed to initialize might change in future versions of SK8. Use the functions initializerArgument to extract information from the initargs object.x me (an Object): An Object. original: The original object on which new or copy was invoked to create a child or copy. child: This is either True or False . If the object is created via new, then this is True . If the object is created via copy, then this is False . initargs: This is an object which contains information about all the keyword arguments (and their corresponding values) that have been passed to new or copy when this object was created. You should use the function initializerArgument to obtain from this object the value for any argument that you are interested (including a list of all arguments that have been passed in). Example One of the many uses of initialize is to create a complex new object. For example, the TextField object is composed of a Scroller and an EditText component. Whenever a new TextField is created, its initialize handler ensures that a copy of each component is created. Suppose you want to create an object called Beeper which beeps whenever a child of that object is created. initialize will beep as many times as the number in that child's property 'beepCount'. The example shows you one way of doing this. (Note the use of the initializerArgument function.) Page 481 Draft.

You can use initializeFromStore to perform any special load-time intialization for your objects. InitializeFromStore is responsible for performing all initialization required for the object to be functional insofar as your own objects require this. The inverse function saveToStore lets you save the state of your object before it is saved by the object store. You must always call the inherited handler before performing your own initialization. If it returns False , then you should return False without any further processing. me (an Object) Example Suppose that you have an object (say, called NeatServerClient) that maintains a connection to some server in the network and that your object maintains some platform-specific information about the connection. You could use initializeFromStore to restore this information based on the state at load-time. Alternatively, you may want to do this at the time the opened event is sent to your project. The first approach allows you to keep the restoration of your object associated with the object itself. on initializeFromStore of me (a NeatServerClient) do inherited setUpConnection me return true end initializeFromStore The second approach requires that the project object know about this other object, as you can here see: Page 482 Draft.

Each item in the Picker can be an arbitrary object. A text representation of each item appears on each line of the picker. The Picker supports scrolling of the list, and selection of items in it (both single and multiple selection), and other capabilities. The Picker has the following properties that you may customize: (1) the ways in which it selects items (2) the spacing between lines (3) whether to sort the items alphabetically or not, and (4) what text to use to represent each item. Picker includes an automatic completion mechanism that moves the selection to match a string entered by the user (the Picker is fast enough to do the update at each character typed). Example To create a simple picker on the Stage whose items are the numbers 100, 200, 300: new Picker with container Stage with items {100,200,300} with location {100,100} See Also items , createTextDisplayItem , alphabeticalDisplay and TextList , IconPicker and StyledPicker.

The default value is True . Note: what is really sorted is the list of strings that represent each item. These strings are obtained by calling createTextDisplayItem . If your createTextDisplayItem handler calls objectString on each item (instead of calling simpleObjectString ), the sorting might have subtle unexpected results. Consider, for example, setting the items of your picker to the list {"Foo", "Foo Bar"} . Calling createTextDisplayItem (which in this anomalous case is calling objectString ) yields the list {"\"Foo\"", "\"Foo Bar\""} . The problem when sorting is that the character \" is greater than the space character and thus, "\"Foo Bar"\" is less than "\"Foo\"" . The items in your picker will then appear in the wrong order: {"Foo Bar", "Foo"} . To fix this problem use simpleObjectString instead of objectString .x Getter get the alphabeticalDisplay of me me (a Picker) Setter set the alphabeticaldisplay of me to NewValue me (a Picker) to (a boolean) See Also createTextDisplayItem , objectString and simpleObjectString of Object . items of Picker Specifies the items that the picker displays. Note that what appears in the picker is not the item itself but a textual representation of it. This representation is created by calling the createTextDisplayItem handler on each item. The default handler uses the objectString of each item. Page 517 Draft.

Setter set the partnerscroller of me to NewValue Makes a scroller and a picker work together. There are two parts to a fruitful relationship between these two objects: (1) a handler that hooks up the right properties using ports and (2) an update handler that keeps the scroller appraised of changes in the picker that concern it (for example, when the number of items in the picker changes, so should the range in the scroller). The properties we will connect are the currentValue of the scroller and the verticalScroll of the picker. Thus, when the currentValue changes, the picker scrolls in the right direction. Notice that the connection should be bidirectional since changing the verticalScroll of the picker by mousing on items should update the scroller as well. me (a Picker) to: A Scroller or False , to disconnect the picker from its old partnerScroller. Example Below we show a slightly simplified version of the actual handler that connects the picker and the scroller in all its glory. The work is divided in three parts: disconnect the scroller from the previous thing it was controlling, connect it the the picker, and store the scroller in the vScroller property of the Picker. Our simple method obviates the first step. It is important to record who the scroller is in a property because the updatePartnerScroller handler of the picker will be called repeatedly to keep them in synch. Note that the safe ports are used (SafeInputPort and SafeOutputPort ). This is because the connection is bidirectional and we want to detect loops. Page 519 Draft.

The idea is to let the picker know that the selection has changed because the picker might want to perform some action at this point. The selection is considered complete when the user releases the mouse or a key (that is, the default picker mouseUp and keyUp handlers call this handler). Consider the SK8 Object Browser. It updates the properties and values panels whenever the selection changes. Since this can take time, you don't want to do do it when you're scrolling in the Objects panel with the mousedown -- you want to do it when the selection ends. Thus, this handler is redefined to update other panels. me (a Picker) size of Picker size me with how with physical This handler returns the number of items visible at one time in the picker or the actor's size handler is called. The how argument specifies which size you want to determine. The options are: 'items' : returns the number of items that are FULLY visible in the picker at any time. 'partialItems' : the number of items that can be seen in the picker at any time. In this count we include items that are only partially visible. This will differ from the size in the previous option by 1 item. False : the Actor size is invoked. me (a Picker) [with how]: One of 'items' , 'partialItems' or False .

PickerMenu (a Menu) This object provides the ability to quickly make simple popup menus. It does this with the same core API used by the Picker object. There is an items property which specifies the list of choices. The user can write a menuSelect handler on the menu and use the selectedItem property to make use of what happens when the user chooses a particular item. Note that the items of the PickerMenu are created dynamically, every time on update . Thus, if you wish to alter the characteristics of one of the items (like add a checkmark ), you must do so in the update handler. See update of PickerMenu for an example of this. Example The following makes a picker menu that lets the user choose a colordepth for a paint window. Note that the items correspond to the number of bits of color, while the text of the items refer to the total number of colors. new PickerMenu with objectname "ColorDepthMenu" set the items of the ColorDepthMenu to {1, 2, 4, 8} on CreateTextDisplayItem of me (a ColorDepthMenu), theitem set numberofcolors to 2^theitem --- This gets the number of colors return (numberofcolors as a number & " Colors") end CreateTextDisplayItem on MenuSelect of me (a ColorDepthMenu) set the colorDepth of the PaintArea to my selectedItem end MenuSelect on Update of me (a ColorDepthMenu) do inherited ---- This creates a PickerMenuItem for each of the items. ---This next line puts a checkmark next to the the item corresponding to the current color depth. set the checkmark of every item whose item = the colorDepth of the PaintArea in my menuitems to true end Update Page 531 Draft.

It should be invoked within a mouseDown event, at which point it lets the user draw the polygon in a variety of ways. When the mouse is released, this handler returns the points of the polygon specified. If startH and startV are not given, the current location of the mouse is used for the first point. This is good enough in most cases. You may provide different values to override. Your values will be expected in Stage coordinates. Page 543 Draft.

[with startv] (an Integer): The vertical location of the start point in Stage coordinates. [with style]: Specifies how the polygon is to be drawn. The default is 'Points' , which means that each click sets one point of the polygon until you doubleClick. 'Regular' only lets you draw regular polygons. The first point is taken to be the polygon's center. You can use the number keys to set the number of sides you want in the Polygon (from 3 to 10 and above using the + and - keys). 'FreeHand' turns the cursor into a pencil and lets you draw an area. 'Symetrical' and 'Symegon' are very exciting: try them! [with multipledraw]: Ignored. [with boundsrectset] (a boolean): If True , the points of the polygon passed in the me argument are set to the points obtained by direct manipulation.

The center of rotation is the point specified by the hAnchor and vAnchor arguments if given. If not, the polygon's anchor is used. If the polygon's anchor is False , its location is used instead. Notice however that as you rotate the polygon its location will change slightly causing the polygon to eventually move in its container. In general you should make sure the anchor is set before attempting multiple rotations. This is shown in the example below. Page 545 Draft.

The Polygon's radius and rotation can be set through the optional radius and phase arguments. me (a Polygon) [with numsides]: The number of sides desired. If not specified, the current number of sides is used. [with radius]: The distance from the current location of the polygon to each vertex in the regular form of the polygon. [with phase] Port (an Object) A Port is a SK8 object that allows a change in a Property's value to cause side effects; most typically, setting the value of a Property of another Object. Ports are attached to individual Object instances. The following figure illustrates where a Property of Object B follows any changes to the value of a Property of Object A. An illustration of Ports. <illustration here in original documentation> There are three kinds of Ports: InputPorts, OutputPorts and InputOutputPorts They are all children of Port. Each is “attached” to a specific Property of an Object, and the Ports are then“wired” together. (For nomenclature, “attaching” connects a Port to a Property of an Object, “wiring” connects Ports together.) When a Property of an Object changes, the OutputPort attached to it activates; which in turn, activates the InputPort that it is wired to; which in turn, sets the value of the Property the InputPort is attached to. InputOuputPorts allow two or more Properties to “track” each other so that when any of the Properties changes value, the others are set to the new value. Their wiring is functionally different from the other types of Ports, and since some confusing issues would arise if InputOutputPorts were to be wired to the other types of ports, such wiring is not currently permitted. This isn't a limitiation however, since any number of any type of Port can be attached to a property. Page 548 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 e n a b l e d o f P o r t A port has a “signature” which specifies an object type to be used to restrict the set of other Ports that this Port can be wired to. An error will be signaled if there is an attempt to wire an OutputPort to an InputPort with a signature specifing a type that is not equal to or a subtype of the OutputPort's signature. This is most useful for the autowire operation, where all you specify to Objects to wire together, and wires will be connected between the two Objects wherever the signatures permit. Ports can also filter the values they transmit and receive. For any Port, you can specify the “valueType”, i.e. the type of the Object, or a list of types of Objects it will respond to. Properties of Port enabled of Port Returns True if the Port is enabled or False if the Port is disabled. Getter get the enabled of me Setter set the enabled of me to NewValue feedbackaction of Port Getter get the feedBackAction of me Setter set the feedbackaction of me to NewValue portobject of Port portObject returns the value of the portObject property of the Port, i.e. the Object that the Port is attached to. Setting the portObject has the effect of detaching the Port from whatever object the Port was attached to and attaching it to the same property of the specified Object. (Note: an error will occur in the case where the new Object does not have the same Property as the Page 549 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 p o r t p r o p e r t y o f P o r t old Object; we don't want the opportunity to leave ports attached to things that don't exist.

Signatures are used to limit the selection of Ports that a Port can be wired to. Each Port has a signature slot, by default set to True (no restrictions), and when two Ports are wired together, their signatures are tested for compatibilty. The signature can be of any of the following forms: A single Object. Specifies an Object. For an OutputPort to be wired to an InputPort the signature of the InputPort Object must inherit from the signature of the OutputPort Object. {and Object1 Object2...} Specifies the intersection of a set of objects. An OutputPort signature of this form requires that any InputPort wired to it have a signature that inherits from all of the Objects. An InputPort with such a signature specifies that any OutputPort wired to it have a signature that is an ancestor of all the Objects. {or Object1 Object2...} Specifies the union of a set of Objects. An OutputPort signature of this form requires that any InputPort wired to it have a signature that inherits from (but not equal to) any of the Objects. An InputPort with such a signature specifies that any OutputPort wired to it have a signature that is an ancestor (but not equal to) any of the Objects. {for Object1 Object2...} Specifies the inclusive union of a set of Objects. An OutputPort signature of this form requires that any InputPort wired to it have a signature that inherits from (or equal to) any of the Objects. An InputPort with such a signature specifies that any OutputPort wired to it have a signature that is an ancestor (or equal to) any of the Objects. True Specifies a wildcard. A Port with a signature of this form may be wired to any Port, except those with a signature of False . False Matches nothing. This Port can't be wired to anything. Wiring InputOutputPorts together requires that the signatures be compatible in both directions. In order to maintain consistency, the signature of a Port can only be set when it is not wired to anything. Note: See also: autoWire, portsCompatiblex Getter get the signature of me Page 551 Draft.

A disabled Port does not activate and therefore functions as if it were not attached to any property nor connected to any other Ports. The disabling feature was originally implemented for troubleshooting complex networks of Ports, though it could also be used for other purposes. (Can anybody come up with any?)

See Also The Condition System section of the User Guide's SK8Script Language chapter project (an Object) In SK8, you organize all of your work into one or more projects. A project is the workspace for what will eventually become the title, application or tool that you wish to build. Everything that you put into a project will find its way to the delivered title or tool. Projects are modules that can be organized into a hierarchy such that objects in one project can be accessible in another project. SK8 itself is a project, whose object name is SK8, which contains the core functionality of the SK8 system. All projects must therefore be directly or indirectly rooted in the SK8 project. A project that "uses" another project in this way is said to be a subproject of the other: conversely, a project used by another project is said to be a superproject of the other. Subprojects of another project are said to be peer projects. A project can have one and only one superproject (the default is, of course, SK8 itself), but it can have as many subprojects as desired. Page 555 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 c o n d i t i o n r e s p o n s e s o f P r o j e c t Each project object, though it is stored along with all objects of a project into a project store file, is actually created in the space of its superproject. This permits peer subprojects of another project to be able to directly access each other's project objects. Therefore, although the objects in peer projects cannot access each other, an API between these projects can be designed around the project objects themselves. Note: You should never directly modify the Project object.x See Also See also Library object Properties of project conditionresponses of Project Getter get the conditionResponses of me Setter set the conditionresponses of me to NewValue constants of Project Getter get the constants of me with inherited with private Returns a list containing all of the constants in the project.

By default all events sent to the Proxy get forwarded to the original object. Customizable behavior can be implemented by adding new handlers to Proxies, or by adding handlers that shadow handlers of the original object. A typical application would be where one wants to display an abbreviated version of an object, or display an object in a completely different way in a separate context. A Proxy has one property, originalObject, the object that the Proxy is standing in for. Any number of Proxies may be created to stand in for an object. Proxies may stand in for other Proxies. Note: This implementation runs on a simple rule: an event is passed on to the original object only when the event is not handled by the Proxy. This might cause some confusion in the case where a handler exists for the original object, and a before handler with the same name is added to the Proxy. The original handler will not be run as the before handler will take it's place. For this situation, if you wanted to have the before handler run before the original object handler, you would need to add a primary handler to the proxy that simply called the handler on the Proxy's original object.x Example Page 577 Draft.

It can be created in various ways: from the clipboard, from a handle, from a resource, from a resource in a file, from a data-fork-only file. It represents only the movie data itself. To play a QuickTimeMovie , you must create a QuickTimeRenderer and set its media property to the QuickTimeMovie . In native QuickTime, a Movie object serves both as the representation of the movie's attributes and as the player (or renderer, using SK8 terminology). SK8 differs from native QuickTime in that it has two separate objects for these two. In addition to the QuickTimeMovie object, there is a QuickTimeRenderer ) object for rendering (i.e. playing) movies. QuickTimeMovie has virtual Page 594 Draft.

The default time scale was chosen because it is convenient for working with common video frame rates of 30, 25, 24, 15, 12, 10, and 8. (Adapted from IM-QuickTime p. 2-190.) Getter get the timeScale of me Calls T_GetMovieTimeScale, IM-QuickTime p. 2-190. me (a QuickTimeMovie) Setter set the timescale of me to NewValue In response to setting the timeScale , the Movie Toolbox adjusts the edit list of the movie's tracks so that movie playback is unaffected. If you change a movie's time scale by setting it to a smaller value (thereby losing precision in the movie's time values), the Movie Toolbox may edit information from the movie. In general, you should only increase the time scale value, and you should try to use integer multiples of the existing time scale. SPECIAL CONSIDERATIONS Do not set timeScale if you have edited your movie. Doing so quantizes the beginning and the end of the edits to the new units. Therefore, if you do not use an integral multiple, the position of your edits may change. (Adapted from IM-QuickTime p. 2-189.)

See IM-QuickTime, p. 2-204. me (a QuickTimeMovie) id (a NonNegativeInteger) QuickTimeRenderer (a DynamicRenderer) A QuickTimeRenderer is a DynamicRenderer that renders a QuickTimeMovie object into one of the regions (fill, text, or frame) of an Actor. It can be used to play a QuickTimeMovie or simply to show a frame of the movie. Unlike in native QuickTime, in SK8 you don't play a QuickTimeMovie directly; rather, you set a QuickTimeRenderer's media to a QuickTimeMovie and tell the QuickTimeRenderer to play the movie. When you set a QuickTimeRenderer's media to a QuickTimeMovie the QuickTimeRenderer creates a MovieController component instance (see IM-QuickTime Components, ch. 2) which it uses for its operation. When the media property transitions to False , that MovieController component instance is discarded. If a QuickTimeRenderer is not rendering any Actor, it can still be used to play a movie, but only the sound tracks will be played.

Handlers of Rectangle getshapefromuser of Rectangle getShapeFromUser me with starth with startv with style with shiftconstraint with multipledraw with boundsrectset This handler provides a direct manipulation interface to obtain the boundsRect of a rectangle. It should be invoked within a mouseDown event, at which point it lets the user drag the outline of the rectangle from the mouseDown point to the current location of the mouse. When the mouse is released, this handler returns the coordinates of the rectangle's boundsRect as a list of 4 values. If startH and startV are not given, the current location of the mouse is used. This is good enough in most cases. You may provide different values to override. Your values will be expected in Stage coordinates. Page 675 Draft.

Renderer (an Effect) A renderer is an object that knows how to "paint" a mask in an arbitrary way. Renderers implement the render handler that gets called to paint some mask. All drawing in the graphics system is done by calling render to paint parts of actors (the frame, the fill or the text regions). SK8 comes with a wide variety of renderers which can be extended in various ways. The simplest way is to make new renderers of types that are already supported and vary their parameters to obtain different effects. You can do this with the renderer editors provided by the ProjectBuilder. If the renderer in Page 677 Draft.

All drawing in the system is done through calls to this handler. Note: This handler should not be called directly by the user. The SK8 graphics system calls render to draw all actors. If you want to redraw and actor use lightForceRedraw instead. Render gets called in the middle of the draw loop. You should not, in the body of this handler, perform any action that might cause the draw loop to be asked to restart itself. If you do you will crash your system. All you should be doing in this handler is Pen and Mask operations and other calls to render. Examples of operations that will crash your system are: showing and hiding the actor, changing the fillcolor, changing the boundsRect , etc. Do not do it!x me (a Renderer) theactor (an Actor): The actor currently being rendered. Most renderers ignore this argument since all they do is paint the region passed to them. region (a Mask): The mask that is to be painted. thePaper: The surface on which the drawing takes place.

The default handler returns False . Translucent me When you set the fillcolor (or frameColor ) of an actor, the system checks whether the new color is translucent. If so, the actor is marked as translucent which changes the way the graphics system draws it in order to achieve this effect. Drawing translucent actors is a lot less efficient than drawing opaque actors and thus you should minimize the use of this effect when possible. Page 680 Draft.

If you make a new renderer which is translucent, you should define this handler for it to return True . Note: Since an actor changes from being considered opaque to translucent when you set the fillcolor (or framecolor), redefining this handler will not update all actors that use this renderer until the fillcolor is set again.x me (a Renderer) Example Consider a Rectangle called Pipo whose fillColor is set to coolRenderer (a renderer we are working on).

It allows you to navigate the file hierarchy normally. When a file that contains resources (in the resource fork) is selected the ResourceChooser shows all the resource types in it. Doubleclicking on a resouce type shows all the resources of that type. When the user clicks on an individual resource, the outputHandle property of the resourceChooser is set to a SK8 resource object (eg. QDPicture ) whose mediaData property has the handle to the resource selected. Thus, you can turn this object into a browser component by adding an output port on the outputHandle property. You can see this object at work in the "Import Media Dialog". Page 681 Draft.

Properties of RoundRect roundedness of RoundRect This property controls how the rounding at the corners of the roundRect will be. The roundRect is constructed by replacing the corners of a rectangle with ovals that are placed on them. With this property, you control the size of these ovals. The default value of this property is {'auto', 'auto'} , meaning that for both the width and height of the Ovals, the system computes a default size. You can set this property to two numbers, thus specifying yourself the size of the ovals to use. Getter get the roundedness of me me (a RoundRect) Setter set the roundedness of me to NewValue me (a RoundRect) to: A list of two items specifying the width and height of the ovals to use to build the RoundRect's corners. Each value can be 'auto' or an integer. In the first case, the system uses a suitable size for the ovals. Page 686 Draft.

It should be invoked within a mouseDown event, at which point it lets the user drag the outline of the RoundRect from the mouseDown point to the current location of the mouse. When the mouse is released, this handler returns the coordinates of the rectangle that would be necessary to inscribe the resulting RoundRect as a list of 4 values. me (a RoundRect) [with starth] (a Number): The horizontal location (in Stage coordinates) of the start point of the outline drawing operation. If not given, the location of the mouse is used. [with startv] (a Number): The vertical location (in Stage coordinates) of the start point of the outline drawing operation. If not given, the location of the mouse is used. [with style]: Use the style argument to specify how the RoundRect is to be drawn. The default is 'CornerToCorner' , which means that the starting point is one of the corners of the bounding rectangle. The opposite corner is the point where the mouse is released. 'CenterOut' means that the starting point is the center of the rectangle and the point where the mouse is released is a corner of the rectangle. [with multipledraw] (a boolean): If True , allows drawing of multiple roundRects using the option key. [with shiftconstraint] (a boolean): If True , pressing the shift key while moving the mouse lets the user constrain the bounding rectangle to a square. The default is True . [with boundsrectset] (a boolean): If True , when the mouse is released, the boundsRect of the RoundRect given as the me argument is set to the boundsRect specified.

The space between the scroller's arrows represents the valid range, and the position of the thumb's top edge in it represents the selected value which we call the currentValue . The currentValue can be changed by dragging the thumb and clicking on the arrows or the body of the scroller. The most common use of scrollers is to allow the scrolling of text in EditText fields or the items of a picker. In this latter case, the range of the scroller is the number of items in the picker. To hook up the scroller and the picker, you just need to make sure that each time the currentValue of the scroller Page 715 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 b o d y o f S c r o l l e r changes, the picker's verticalScroll property is set to it. This can be done using ports as illustrated in the partnerScroller property of Picker. The SK8 scroller's thumb is constantly resized to provide an instant indication of how much of the selection range is actually visible in the scrollee. See Also scrollStep , pageStep , minimumValue , maximumValue , currentValue and thumbView and partnerScroller of Picker for a description of how to associate a picker to a scroller.

In order to be visible, an actor has to be ultimately contained by the Stage. All actors that are directly contained by the Stage object becomes windows. The Stage is special in that it is a unique object: you cannot create a new Stage . Thus, all your projects share the Stage . This means that the Stage cannot be specialized by the user. SK8 provides a mechanism for notifying objects in arbitrary projects about some events that happen to the Stage. Each object that implements this mechanism actually chooses which events to support for notification. The Stage supports notification for the following events: mouseEnter, mouseLeave , mouseDown , mouseUp and dropped . Note: since the Stage is the root of the containment hierarchy and many handlers follow the container relation up to it, some handlers might be careless and treat the Stage as just another actor when the Stage is not an actor at all. To guard against this eventuality, a number of Actor handlers have been defined for the Stage . In most cases they do not do anything.x The Stage defines the physical coordinate system of SK8. The origin of this coordinate space (the {0,0} point) is located at the topleft corner of the main monitor (the monitor with the menubar on it). The scale of this system is 1 and the unit of measurement is the pixel. This means that if the physical size of an actor is {100,30} , the actor is 100 pixels wide and 30 pixels high. Page 754 Draft.

When the user presses a key while holding down the command key, the resultant keyDown event is sent to the object in the currentCommandKey property of the system. Setting the currentCommandKey to False will prevent the keyDown event from being sent when the command key is depressed. Typically, the currentCommandKey object will be a MenuBarActor in some active toplevel actor. The toplevel actors are responsible for setting and removing targets from the currentCommandKey property of the System object. The currentCommandKey can be set to specify any type of object, e.g., a Menubar. In the Macintosh user interface, shortcuts to selecting menu items are often available by pressing a command-key combination. For example, in most Macintosh word processors, you can copy a selection of text either by selecting 'Copy' off the edit menu or by holding down the command key and pressing 'C'. If the menu bar object includes scripts that can process menu selections as well as their command-key shortcuts, designating the menu bar object through the currentCommandKey property will cause the command-key events to be correctly processed.

That is, when setting an item, a table will either overwrite the data in the existing entry under the given key, or if there was no entry, create and add a new entry for the data under the given key. Table objects obey the collection protocol, so they can be used in iterative constructs. The order of the items in a table is nondeterminisitic. Note: The special “type” TablePair can be used to access key-data pairs in a table as ListPair s, as in TablePair x in someTable or every TablePair in someTable .x There are three different kinds of tables: Table : Uses the = operator when testing whether a key is matched. ObjectTable : A faster but less generalized form of table, this uses the same object operator when testing whether a key is matched. Uses the is a operator when testing whether a key is matched. In other words, it is keyed on type-conformace of a given object to the key object — i.e. an object matches the key that is its nearest ancestor (or itself). Note: When setting an item corresponding to a given key, TypeTable uses the same object operator (rather than is a ) to find the key (or determine that it needs to be added).x TypeTable : See Also ObjectTable , TypeTable , TablePair Page 781 Draft.

It should not normally need to be accessed directly. Getter get the data of me Setter set the data of me to NewValue TablePair (a ListPair) TablePair is a special “type” that exists solely for the purpose of accessing key-data pairs in a table as ListPair s. Example set set set get get t to a new Table item 'Bob' in t to 1 item "blah blah" in t to 2 every item in t -- returns {2, 1} (note that the order may vary) every TablePair in t -- returns {{"blah blah" . 2}, {'Bob' . 1}} TablePicker (a Rectangle) This is a two-dimensional picker for displaying sets of text and renderers. It follows the same basic API as the regular picker. It has an items property, a selecteditems property, a selectioncompleted handler. It is different in that the items property accepts an array of items Page 782 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 c o l u m n L i n e s S i z e o f Ta b l e P i c k e r The selected items are stored in the array stored in the selectionArray property. When items are displayed, first createDisplayItem is called on each item. By default, this leaves renderers alone and calls createTextDisplayItem on the item to create a string. These display items are stored in an array stored in the imageArray property. The picker gives you control over the sizes of individual rows and columns. There are two properties, rowHeights and columnWidths which contain a list of integers which are the sizes of each individual row and column. By default, the picker will scale the sizes of its rows and columns to fit the size of the text (or renderer ) inside of it (augmented by the properties minHeight and minWidth which prevent any item from being below their values). These are computed by the handlers recomputeColumnWidths and recomputeRowHeights . You can override these values either by redefining these handlers or setting the properties manually. For convenience if you set the rowHeights or columnWidths to a single integer (rather than a list) it will make every row or column that consistent size. In terms of Highlighting the selected items, by default it paints the item in the system's hilighting color. You can turn this on and off with the highlightSelection property. In addition, you can hilight items with a highlightColor and then set the size of the hilight with the selectionBorder property (which takes a number which is the inset size of the hilighting halo). rather than a list of items. (Actually, as a convenience, if you set the items to a list of lists, it will construct an array for you by setting the items of each row to each list.) There are properties like Rows , Columns , and Dimensions to let you manipulate this array.

This list of lists is converted into an array where each sublist is assigned a row. For example, if you set the items of my tablepicker to {the knownchildren of rgbcolor, the knownchildren of actor} , the tablepicker will have two rows. The first row will display all the colors, the second row will display the names of the actors.

This cell can be typed into to provide new information for the cell (or any other purpose). The functionality can be accessed using the handlers defined below. This is useful for making spreadsheet type objects. For example, if you wish to allow the user to select a cell and type in place, this functionality would provide you with the structure to do so. See the TablePickerEditor object for more information. Note that you can redefine the behavior of both the tablepicker and this editor to achieve the results you want.

The scroller is affixed to the editText. The TextField is the editText. This actor is a bit strange in that it behaves as a rectangle containing the editText and the scroller when in reality there is no such thing: the scroller and the editText are always placed in the same container and the boundsRect handler is modified to make them appear to be one entity.

[with relative] (a boolean): If True , the values provided are assumed to be offsets from the current boundsRect. [with justmoving] (a boolean): If True , you inform the graphics system that the actor is not actually changing size, but just moving. This allows the system to do a number of optimization. This argument also determines whether moved or resized gets called on the actor. textList (a Rectangle) A rectangle containing a picker, a scroller and a titleBar. TextList actors provide a fast and simple one-dimensional table and can be seen in most of the system's browsers. You can see this actor as just a scrollable picker, since most of its functionality comes directly from the picker. All the picker related handlers and properties just delegate the call to the textList's picker. If you don't want to use the titleBar, you can just hide it and the textList will not display it.

Confidential. ©1995 Apple Computer, Inc. 5/8/95 w r i t e w o r d o f Te x t S t r e a m Properties of Today Handlers of Today translator (an Object) Translators are objects that know how to turn SK8 objects into forms that can be used by the outside world (e.g., the Mac OS) and vice versa. By adding more translators you can increase the kind of SK8 objects that can be exported to other apps in your system and at the same time the number of objects that can be brought into SK8 from any external source. A child of Translator must be implemented for each kind of data translation (e.g., one which takes a SK8 ImageRenderer and turns it into a "PICT" file). SK8 provides facilities to query the kinds of translations available and for automatically attempting translations. (Note that SK8 will adapt itself to the available translators.) A convention is followed in the naming of translator objects. The name starts with the SK8 object the translator exports (eg. Sound ). Then "to" followed by the name of the operating system analog of the SK8 object (eg. "snd" for the resource type). We end the name with "Translator". The translator in our example is thus called: SoundTosndTranslator Translators do all their work with the import and export handlers. You can see translators at work in the Import Media Dialog and in the SK8Clipboard when you (for example) cut a PICT in some graphics program and paste it into SK8. Note: Writing translators is an inherently low level endeavor requiring use of the foreign funtion interface to (very possibly) call traps.x See Also import and export with their associated low level handlers, canImport , canExport and the Clipboard object for more details on how translators are used. The following functions are also defined: importTranslatorsApplicable , findImportTranslator, findExportTranslator. Page 838 Draft.

This property exists to allow translators to do two level translation: from a pointer to media to a SK8 media object and then to a higher level object that uses the media. Consider for example the ImageRendererToPICTTranslator. It takes a reference to a "PICT" and makes an imageRenderer out of it, the finalObject is ImageRenderer, but the internal object (the media analog) is QDPicture. Getter get the finalObject of me If the finalObject is not False , it is returned. Otherwise the finalObject and the internalObject are the same and the internalObject is returned. me (a translator) Setter set the finalobject of me to NewValue me (a translator) to: An object or False to indicate than the finalObject is the internalObject . See Also internalObject . internalobject of Translator Specifies the SK8 media object that this translator creates when the media is imported. This object is the actual analog to the media being imported. If importing a "PICT" resource, the internalObject would be a QDPicture . If importing an "snd " resource, the internalObject would be a SoundRSRC . Page 839 Draft.

Handlers of translator canExport of Translator Returns whether this translator knows how to export the source provided. The source must inherit from the translator's finalObject . The destination can be a file, a media or the SK8Clipboard . If it is a descendant of Media , it must inherit from the translator's internalObject . me (a translator) source destination canExport me, source, destination canimport of Translator canImport me, source, destination Returns whether the translator specified can perform the import operation required. The arguments should be provided in the exact same format in which import would be called. The source argument specifies the source of the import. If it is a file object, it is assumed that the media in question is a handle in its data fork. The file must exist and be of the right type. If it is a media object, it is assumed to be a handle in the resource fork of a file. Finally, it is is the Sk8Clipboard object, the handle is assumed to be in the scrap. Page 840 Draft.

[destination]: The Sk8 object that would be created as a result of the import. See Also import . export of Translator export me with source with destination This handler exports media from SK8 to the outside world. Calls exportToFile, exportToResource or exportToClipboard depending on the type of the destination. me (a Translator) with source: The object whose media is to be exported. Should inherit from the translator's finalObject . with destination: Either a file, a media object or the SK8Clipboard . exporttofile of Translator exportToFile me with source with destination Performs an export operation writing the data to the data fork of the file specified in the destination argument. This handler must be defined by individual translators. The default handler reports an error when called specifying that the translator does not know how to perform this operation. me (a translator) with source with destination: The file the data will be written to. externaltype of Translator externalType me Returns the OSType the translator knows how to deal with.

The data may be found in many places in the outside world: in the data fork of a file, in the resource fork of a file or on the clipboard. This handler knows how to import from any of these sources. The source argument should completely specify all the information required to get to the data. If the data we want to import is in the resource fork of a file, the source should be a file object pointing to this file. The file must really exist and its macFileType must be the same as the translator's externalType . If the data we want to import is a resource in the resource fork of a file, the source must be a SK8 media object with the right restype . Its file must exist and a resource of the right resourceId should exist also. As an example, consider wanting to import a "PICT" handle that is the PICT #2345 from the resource file FooFile. An appropriate source would be created as follows: new QDPicture with file FooFile with resourceId 2345 The destination must be an object that inherits from the translator's internalObject . Note that the destination object must be created by you in advance to calling the import handler. The import handler will just import the real data and fill in the destination to point to it. In the destination you specify whether you want the media to be stored in the project file of the destination or in the file the media originally is. This is specified by setting the file of the destination. Continuing our example, here is an appropriate destination object to import the PICT handle: new QDPicture Finally, if the media is in the clipboard (say after copying a PICT from a program like MacDraw), all you need provide is the SK8Clipboard object. Note that if no file is specified, the QDPicture's file is its project file meaning that the media will be copied to it. No resourceId is required either since the import handler will fill it in after is has copied the media. To tell the system to leave the media where it is you need to set the file of the destination to a file object that points to the file where the media really is. Note that although you can get this file from the file of the source , you must ensure that the file Page 842 Draft.

For that you can use the findFileInProject function as follows: set theFile to findFileInProject(the source's file, the destination's project) new QDPicture with file theFile Now you are ready to call this handler. This handler checks the type of the source and then calls importFromFile , importFromResource or importFromClipboard to do the work.

It records the state of the property or properties that have been set by calling the function UndoableSet or that have been "undone" or reset by calling the function UndoLastSet . These functions work as follows. When UndoableSet is called to set the value of a property on a set of objects, the old values of these properties are stored in the UndoableSetLog . Whenever UndoLastSet is called, it resets the values of the properties to the original values and stores the current values so the undo can be undone. Note that this is not a full undo in that if a property has some side effects which are not undone by resetting the property than such side effects will not be removed.

It takes either a boundsrect or a set of points (e.g. the values returned by a getshapefromuser call) and returns a list of four values. These four values are described below. The first value is the clicked actor. If the result was a click and not a box/lasso, this is the object that was clicked on. Otherwise it returns False . The second value is a list of the Contained Actors. This is an ordered list of lists. Each sublist is a list of objects fully contained by the region. Each list represents a level of containment in one actor. Thus each list is a list of all the actors fully surrounded at a specific level in a specific actor. For Example: The first list is the list of actors which are fully surrounded at the highest level. For every item in this first list there will be another list of all the items inside because all of these items will be surrounded. There will also be lists of objects which are contained by the halo but are not as high up in the containment hierarchy as those in the first list, etc. The third value is a list of the TouchedActors. This is an ordered list of lists in the same form as (2) except the objects in the lists are ones that are touched in any way (partially or fully) by the region defined. The fourth value is the Lowest Fully Contained By Actor. This is the deepest actor which fully contains the region. (There can be at most one of these) This function takes an avoiding keyword which can specify an object or a list of objects which are to be ignored when constructing these values. pointList: This takes either a boundsRect or a set of points to specify the selection area. [with avoiding]: This can specify an object or a list of objects which are to be ignored when constructing these values. ascii ascii ch This function returns the ASCII value its argument.

If you create an event dispatcher object you will need to call this function when an event you support for dispatching takes place. eventDispatched: The object that got the event. event (a Symbol): The event that is about to be dispatched. [args]: All the arguments that the original event passed. Page 886 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 d i s p o s e d i a l o g Example Let us create a custom event dispathing object. You should note before we start that this event dispatching mechanism is provided for strange cases in which normal handler definition will not work (eg. defining handlers for objects in another project). With that out of the way we may continue... In this example you can see what the Stage object had to go through in order to be able to dispatch events. First we added the eventInterests property and initialized it to contain a special data structure that keeps track of the event interests. addProperty Stage, 'eventInterests' set the eventInterests of the Stage to makeEventInterestsHashTable() Now we need to choose the events that will support dispatching. Let us make mouseDown supported. For that we define the mouseDown handler of the Stage as follows: on mousedown of me (a Stage) dispatchToInterestedObjects me, 'mouseDown' end mousedown And now, each time the mouseDown event takes place, all the interested objects will get mouseDown called on them. See Also addEventInterest , removeEventInterest . disposedialog disposeDialog objects with textfont with textsize with width with height with h with v Given an object or a list of objects, this function will display a dialog asking “Do you wish to clear references to YourObject?” Two buttons are displayed: “Yes” and “No”. If the “Yes” button is selected the object(s) will be made ready for garbage collection. Note that it does this by setting objectnames to false, removing the item's contents, removing the item from its container, and removing the items from the knownchildren list. Page 887 Draft.

[with cancel] disposeMem disposeMem a-macptr Advanced users sometimes call code written in languages other than SK8 Script. Such code is called "foreign" code. Sometimes foreign code manipulates data which must not be moved and must be explicitly allocated and freed. In general it is tedious and error prone to do this. However, if you must bit twiddle and feel that you really know what you are doing, you can allocate and deallocate static memory explicitly. This function lets you deallocate memory which has been allocated by use of one of the functions newMemPointer or newMemHandle. Note that such memory operations are unsafe. You can easily crash your machine if these memory management functions are used as you are stepping outside of the safety of the SK8 system. foreignMem Example disposeMem( aMemHandleOrMemPointer ) See Also newMemPointer, newMemHandle Page 888 Draft.

If there is a syntactic error in the definition, a ScriptSyntaxError is raised; otherwise the result of evaluating the definition is returned. If the warnings argument is True (the default) then warnings regarding local variable usage in the given function or handler definition may be sent to the systemLog . The outerGlobals and outerLocals arguments may be used to indicate to the evaluator whether a particular undeclared variable in the definition should be assumed to be a local variable or a global variable. Each of these arguments, if given, must be lists of symbols. A symbol in either of these lists is ignored if it does not appear as a variable in the handler definition or if it does appear but is explicitly declared local or global. If the selfStoring argument is True (the default) then the definition will be written into the targetProject 's project file if the function or handler is succesfully evaluated and activated. The documentation argument, if supplied, should be a string containing documentation to associate with this function or handler. This argument is ignored if the selfStoring argument is False . The versionID argument, if supplied, should be an integer representing a date and time in universal time encoding; if this argument is not supplied, the current time will be used as the version ID.

[int]: The integer in question even int Example even (2)-- returns True 9 is even-- returns False See Also odd eventActor eventActor Returns the Actor that is currently receiving events from the event system. This is usually the actor under the mouse. Example Since events are propagated up the containment hierarchy, it is common to take into account whether an actor is the event actor before following a course of action. What we are in effect doing, with this variable is distinguishing between two cases: when an actor is the original recipient of an event and when it is not. Page 896 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 e v e n t H To illustrate the problems that arise from this consider a Scroller called NastyScroller and its ScrollerDownArrow. On mousedown , the downArrow passes the event to its container to let it know that a mouseDown event has happened within it. When the inherited handler returns, the down arrow does its usual thing (scroll the scroller down while the mouse is down). Consider the following handler: on mouseDown of me (a NastyScroller) drag me end mouseDown If we now press the mouse on the scroller's down arrow, NastyScroller gets a mouseDown event at which point it takes control of the mouse (drag returns when the mouse is up). So, when we get to what we really wanted to do (scroll the scroller) the mouse is up and nothing happens. That is why we should distinguish between the two cases above. on mouseDown of me (a NastyScroller) if eventActor() = me then drag me end if end mousedown The eventActor function comes to the rescue. At this point we might consider changing the objectName of NastyScroller to "NiceWellBehavedGoodCitizenScroller" .

If the declaration argument is True (the default is False ) then the argument sequence is represented in a form suitable for use in a function or handler definition. This argument is ignored if the call argument is True . If the call argument is True (the default is False ) then the argument sequence is represented in a form suitable for use as the argument list in an expression that calls to the given function or handler. The primaryArgument and setterArgument arguments, when used in conjunction with the call argument, control whether the primary argument (if there is one) and the setter argument (if there is one) are included in the string.

Notice that the importing is a separate step that has nothing to do with this function. This function is provided as a utility to allow people to make use of the vast number of icons that have been created and stored using the icon family resource types ("ICN#", "icl8", etc.) The name and ids of every resource is preserved. Page 910 Draft. Confidential. ©1995 Apple Computer, Inc. 5/8/95 i m a g P a r t sourceFile (a File): The file that contains the "icl8" resource to be translated into "cicn" resources. [with destinationFile] (a File): If specified, should be the file where the "cicn" resources should go. If the file does not exist it is created. If this argument is False , the new resources are placed in the sourceFile. [with selectedIds]: A list of integers or False . With this argument we can specify which resources to be translated. If this argument is not specified, every resource of type "icl8" is translated. Example Suppose that you get a file full of icons that you want to use in your SK8 project. You try import them with the MediaBrowser but find out that SK8 does not "see" any of the icons. This might be because the icons you got are stored in the "icon family" format. You need to turn these icons into "cicn" resources before SK8 will be able to deal with them. The first step is to call this function to get this done. Assuming the iconFile is the file containing the icons, we type: icl8ToCicn iconFile Now the icons are translated into "cicn" resources which have been saved into the same file (iconFile). We can now import these icons using the MediaBrowser in the usual way. imagPart imagPart Number Returns the imaginary part of the given number. number (a Number) See Also realPart , the function complex , the object Complex importTranslatorsApplicable importTranslatorsApplicable source Returns all the translators that canImport from the source. source: A File , a child of Media or the SK8Clipboard .

This is the value of the systemLog property of SK8 (the object). A call to this function usually results in the object specified being printed providing some feedback to the user. In order to be a suitable systenLog, the object in question has to implement the following two handlers: insertInto which adds the object specified and shows it in some way, and getAttention which should do something to make sure the user notes the message that was sent. obj: The object that we want to send to the system log. [with attention] (a boolean): If true, the system log's getAttention handler is called. Example In SK8, the default systemLog is the MessageBox .

This is useful in dynamically restructuring the inheritance hierarchy. kids (a list): A list of objects which are all in the same project and which have the same set of parents. with objectName: The objectName of the newly created parent. Example Let's say that you have made two different RoundRect buttons in a window. You realize that there should be a prototype Button object that all buttons in your project would share. Therefore, you can call SpliceNewParent of {HappyButton, SadButton} with objectname "Button" in order to create a new RoundRect named "button". You can then add handlers and properties (e.g. an 'enabled' property) to the "Button" object and they will be inherited by the HappyButton and the SadButton. sqrt sqrt Number This function returns the principal square root of its argument.

If it is set to False , Command-. is treated as a normal commandKeyEvent . Otherwise CancelKeyAction should be set to the name of a function to be called with no arguments when Command-. is pressed. Note: The default value of CancelKeyAction is 'abortBreak' .x See Also commandKeyEvent , abortBreak EventsStopForMenus This variable determines whether the event system stays active when a menu is pulled down. The default is False , allowing movies, clocks and animations to be played as menus are pulled down. By setting this variable to True , the standard Macintosh behaviour is obtained: movies do not play while a menu is pulled down. Note: when a menu intersects a playing movie or an animation, the movie will draw itself on top of the menu causing a slightly unpleasant effect. As an author you should be aware of this problem and the two ways to deal with it: you can make sure movies and animations cannot intersect any menus or you can turn off this capability entirely.x InteractiveErrors This variable controls whether or not ChooseResponse (a child of ConditionResponse ) is invokable . If it is set to a non-False value (the default value is False ) then a dialog from which one of the invokable responses can be chosen will be brought up each time an error is raised. Note: In the conditionResponses of SK8 , as shipped, ChooseResponse is the first response for all errors.
