Page 35 The children must be objects that inherit from the UIObject class (which includes all components and screens built with version 2 of the Macromedia Component Architecture); most often, children are a subclass of the View class. This includes movie clips assigned to the class mx.core.View.
Page 36 Description Page Up Selects the previous child. Selection cycles from the first child to the last child. Shift+Tab Moves focus to the previous component. This component may be inside the selected child, or outside the accordion; it is never another header in the same accordion.
Page 37: Chapter 2: Accordion Component (Flash Professional Only)
enabled is a Boolean value that indicates whether the component can receive focus and input. The default value is true visible is a Boolean value that indicates whether the object is visible ( ) or not ( true false The default value is true The minHeight and minWidth properties are used by internal sizing routines.
Page 38: Using The Accordion Component (Flash Professional Only)
Create a new screen named accordionForm. Drag an Accordion component from the Components panel to the accordionForm form, and name it my_acc. With my_acc selected, in the Property inspector, do the following: For the childSymbols property, enter addressForm, addressForm, and checkoutForm. These strings specify the names of the screens used to create the accordion’s children.
Page 39 In the Property inspector, do the following: Enter the instance name my_acc. For the property, enter AddressForm, AddressForm, and childSymbols CheckoutForm. These strings specify the names of the movie clips used to create the accordion’s children. The first two children are instances of the same movie clip, because the shipping address form and the billing address form are identical.
Page 40 In the Actions panel in Frame 1, below the code you entered in step 5, enter the following code (this code adds two TextInput component instances to the accordion’s children): // Create child text input for the shippingAddress panel. var firstNameChild_obj:Object = my_acc.shippingAddress.createChild("TextInput", "firstName", {text: "First Name"});...
Page 41 Using styles with the Accordion component You can set style properties to change the appearance of the border and background of an Accordion component.

Page 43 Property Description Default value The pressed state of the header above the trueDownSkin accordionHeaderSkin expanded child. The rolled-over state of the header above the trueOverSkin accordionHeaderSkin expanded child. The disabled state of the header above the trueDisabledSkin accordionHeaderSkin expanded child. Using ActionScript to draw the Accordion header The default headers in both the Halo and Sample themes use the same skin element for all states and draw the actual graphics through ActionScript.
Page 44 To create an ActionScript-customized Accordion header skin: Create a new ActionScript class file. For this example, name the file RedGreenBlueHeader.as. Copy the following ActionScript to the file: import mx.skins.RectBorder; import mx.core.ext.UIObjectExtensions; class RedGreenBlueHeader extends RectBorder static var symbolName_str:String = "RedGreenBlueHeader"; static var symbolOwner_obj:Object = RedGreenBlueHeader;...
Page 45 _global.skinRegistry["AccordionHeaderSkin"] = true; return true; static var classConstructed_bl:Boolean = classConstruct(); static var UIObjectExtensionsDependency_obj:Object = UIObjectExtensions; This class creates a square box based on the border style: a blue box for the false up, rollover, and disabled states; a green box for the normal pressed state; and a red box for the expanded child.
Page 46 To create movie clip symbols for Accordion header skins: Create a new FLA file. Create a new symbol by selecting Insert > New Symbol. Set the name to RedAccordionHeaderSkin If the advanced view is not displayed, click the Advanced button. Select Export for ActionScript.
Page 47 Accordion class (Flash Professional only) Inheritance MovieClip > UIObject class > UIComponent class > View > Accordion ActionScript Class Name mx.containers.Accordion An Accordion component contains children that are displayed one at a time. Each child has a corresponding header button that is created when the child is created. A child must be an instance of UIObject.

Page 111: Chapter 5: Cellrenderer Api
CHAPTER 5 CellRenderer API The CellRenderer API is a set of properties and methods that the list-based components (List, DataGrid, Tree, Menu, and ComboBox) use to manipulate and display custom cell content for each of their rows. This customized cell can contain a prebuilt component, such as a CheckBox component, or any class you create.
Page 112 About the composition of the List component List components are composed of rows. These rows display rollover and selection highlights, are used as hit states for row selection, and play a vital part in scrolling. Aside from selection highlights and icons (such as the node icons and expander arrows of a Tree component), a row consists of one cell (or, in the case of the DataGrid component, many cells).
Page 113: Using The Cellrenderer Api
Using the CellRenderer API You must write a class with four methods ( CellRenderer.getPreferredHeight() CellRenderer.getPreferredWidth() CellRenderer.setSize() ) that the list-based component uses to communicate with the CellRenderer.setValue() cell (if the class extends UIObject, you can use instead of size() ). The class must be specified in the AS 2.0 Class text box in the CellRenderer.setSize() Linkage Properties dialog box of a movie clip symbol in your Flash application.
Page 114 The following tutorial shows how to create a cell renderer class that displays multiple lines of text in the cells of a DataGrid component. The completed files, MultiLineCell.as and CellRenderer_tutorial.fla are located at www.macromedia.com/go/component_samples. Creating the MultiLineCell cell renderer class A cell renderer class must implement the following methods: CellRenderer.getPreferredHeight()
Page 115 private var owner; // The row that contains this cell. private var listOwner; // The List, data grid or tree containing this cell. // Cell height offset from the row height total and preferred cell width. private static var PREFERRED_HEIGHT_OFFSET = 4; private static var PREFERRED_WIDTH = 100;...
Page 116 c.setSize(__width, __height); // Provides the preferred height of the cell. Inherited method. public function getPreferredHeight():Number /* The cell is given a property, "owner", that references the row. It’s always preferred that the cell take up most of the row's height. In this case we will keep the cell slightly smaller.*/ return owner.__height - PREFERRED_HEIGHT_OFFSET;...
Page 117 Click the Advanced button in the lower-right corner of the Create New Symbol dialog box to enable more options. The Advanced button is available when you are in the basic mode of the Create New Symbol dialog box. If you don’t see the Advanced button, you are probably already in the Advanced view of the dialog box.

These files are located in the CellRenderers_sample folder within the Samples and Tutorials folder on your hard disk at www.macromedia.com/go/ component_samples. The additional installed sample named CellRenderers_Sample displaying a ComboBox and CheckBox.
Page 120: Cellrenderer.getcellindex()
Methods provided by the CellRenderer API The List, DataGrid, Tree, and Menu components give the following methods to the cell when it is created within the component. You do not need to implement these methods. Method Description Returns an object with two fields, CellRenderer.getCellIndex() columnIndex , that indicate the position of the cell.
Page 121: Cellrenderer.getdatalabel()
Description Method; returns an object with two fields, , that locate the cell columnIndex itemIndex in the component. Each field is an integer that indicates a cell’s column position and item position. For any components other than the DataGrid component, the value of is always 0.
Page 122: Cellrenderer.getpreferredheight()
Example The following code tells the cell the name of the data field that it is rendering. For example, if the name of the data field currently being rendered by the cell is , the variable "Price" now equal to "Price"...
Page 123: Cellrenderer.getpreferredwidth()
This example returns a value that is 4 pixels less that the height of the row: function getPreferredHeight():Number /* You know the cell is given a property, "owner", which is the row. It’s always preferred for the cell to take up most of the row's height. return owner.__height - 4;...
Page 124: Cellrenderer.listowner
Example This example returns the value multiplied by 3, which indicates that the cell should be three times bigger than the length of the string it is rendering: function getPreferredWidth():Number return myString.length*3; This example comments out the method: getPreferredWidth() // function getPreferredWidth :: only for a menu or datagrid CellRenderer.listOwner Availability Flash Player 6 (6.0.79.0).

CellRenderer.owner Availability Flash Player 6 (6.0.79.0). Edition Flash MX 2004. Usage componentInstance.owner Description Property; a reference to the row that contains the cell. This method is provided by the List class; you do not have to implement it. Declare it in your cell renderer class and use it as a reference: var owner:MovieClip;...
Page 126: Cellrenderer.setvalue()
Description Method; lets the list tell its cells the size at which they should lay themselves out. The cell renderer should do layout so that it fits in the specified area, or the cell may bleed into other parts of the list and appear broken. If the cell renderer extends the UIObject class, you should implement the method size()
Page 127 Parameters A value to be used for the cell renderer’s text, if any is needed. suggested An object that is the entire item to be rendered. The cell renderer can use properties of item this object for rendering. A string with the following possible values: , and selected "normal"...
Page 128 Because a cell might not exist on the Stage (it might be scrolled out of the display area or it might be reused to render another value) at any time, you cannot directly reference a specific cell renderer instance in the grid. Instead, use the data provider to communicate with a specific cell in the grid.
Page 129 If you want to enable the check box on the second row, you communicate through the data provider. Any change to the data provider (when made through a DataProvider method such ) calls to refresh the display of the grid. This DataProvider.editField() setValue() code would be written in the Flash application, either on a frame, on an object, or in another...

Page 131: Chapter 6: Checkbox Component
CHAPTER 6 CheckBox component A check box is a square box that can be selected or deselected. When it is selected, a check mark appears in the box. You can add a text label to a check box and place it to the left, right, top, or bottom.
Page 132: Using The Checkbox Component
You enable accessibility for a component only once, regardless of how many instances you have of the component. For more information, see Chapter 19, “Creating Accessible Content,” in Using Flash. Using the CheckBox component A check box is a fundamental part of any form or web application. You can use check boxes wherever you need to gather a set of values that aren’t mutually exclusive.
Page 133 To create an application with the CheckBox component: Drag two TextInput components from the Components panel to the Stage. In the Property inspector, enter the instance names minimumAge and maximumAge. Drag a CheckBox component from the Components panel to the Stage. In the Property inspector, do the following: Enter restrictAge for the instance name.
Page 134: Customizing The Checkbox Component
Now, add the following ActionScript to create an event listener and an event handler function: // Create handler for checkBox event. function checkboxHandler(evt_obj:Object) { minimumAge_ti.enabled = evt_obj.target.selected; maximumAge_ti.enabled = evt_obj.target.selected; // Add Listener. testAge_ch.addEventListener("click", checkboxHandler); This code creates a event handler that enables and disables the click minimumAge text field components.
Page 135 A CheckBox component supports the following styles: Style Theme Description Halo The base color scheme of a component. themeColor Possible values are "haloGreen" "haloBlue" . The default value is "haloOrange" "haloGreen" Both The text color. The default value is 0x0B333C color for the Halo theme and blank for the Sample theme.
Page 136 Style Theme Description Sample The color of the check mark. The default value is symbolColor 0x000000 (black). Sample The color of the disabled check mark. The symbolDisabledColor default value is 0x848384 (dark gray). Using skins with the CheckBox component The CheckBox component uses symbols in the library to represent the button states. To skin the CheckBox component while authoring, modify symbols in the Library panel.
Page 137: Checkbox Class
Expand the CheckBox Assets/States folder in the library of your document. Open the symbols you want to customize for editing. For example, open the CheckFalseDisabled symbol. Customize the symbol as desired. For example, change the inner white square to a light gray. Repeat steps 5-6 for all symbols you want to customize.

Page 253: Using The Datagrid Component (Flash Professional Only)
DataGrid component, it is helpful to understand how the List class underlying it was designed. The following are some fundamental assumptions and requirements that Macromedia used when developing the List class: Keep it small, fast, and simple. Don’t make something more complicated than absolutely necessary. This was the prime design directive.
Page 254 Lists perform worse as a function of their visible rows. Although lists can display 5000 records, they can’t render 5000 records at once. The more visible rows (specified by the property) you have on the Stage, the more work rowCount the list must to do to render.
Page 255 Field Identifiers that indicate the names of the columns within the items. This corresponds to property in the columns list. In the List component, the fields are columnNames usually , but in the DataGrid component the fields can be any identifier. label data In the following code, the fields are...
Page 256 The data for a grid can come from a recordset that is fed from a database query in Macromedia ColdFusion, Java, or .Net using Flash Remoting. Data can also come from a data set or an array. To pull the data into a grid, you set the DataGrid.dataProvider...

Page 258: Datagrid Performance Strategies
To create a DataGrid component instance using ActionScript: Drag the DataGrid component from the Components panel to the current document’s library. This adds the component to the library, but doesn’t make it visible in the application. Select the first frame in the main Timeline, open the Actions panel, and enter the following code: this.createClassObject(mx.controls.DataGrid, "my_dg", 10, {columnNames:["name", "score"]});...
Page 259 You may be tempted to make a loop to call for all the DataGrid.addColumn() columns needed. Although this seems like a simple and obvious approach, do not use it. Each time that is called, the data grid adds event listeners, sorts, DataGrid.addColumn() and redraws itself to present the new column.
Page 260: Customizing The Datagrid Component (Flash Professional Only)
Separate data processing from CellRenderer processing. The CellRenderer API lets you display custom cell content in a data grid. A functional requirement might require that you populate the data grid with a ComboBox component or other UI control conditionally. For example, based on a selection in column two, you may repopulate or auto-select options in column four.
Page 261 Using styles with the DataGrid component You can set style properties to change the appearance of a DataGrid component. The DataGrid component inherits styles from the List component. (See “Using styles with the List component” on page 766.) The DataGrid component also supports the following styles: Style Theme Description Both...

Page 263 Setting styles for all DataGrid components in a document The DataGrid class inherits from the List class, which inherits from the ScrollSelectList class. The default class-level style properties are defined on the ScrollSelectList class, which the Menu component and all List-based components extend. You can set new default style values on this class directly, and these new settings are reflected in all affected components.

Page 333: Chapter 13: Dataset Component (Flash Professional Only)
CHAPTER 13 CHAPTER 13 DataSet component (Flash Professional only) The DataSet component lets you work with data as collections of objects that can be indexed, sorted, searched, filtered, and modified. The DataSet component functionality includes DataSetIterator, a set of methods for traversing and manipulating a data collection, and DeltaPacket, a set of interfaces and classes for working with updates to a data collection.
Page 334 The DataSet component uses functionality in the data binding classes. If you intend to work with the DataSet component in ActionScript only, without using the Binding and Schema tabs in the Component inspector to set properties, you’ll need to import the data binding classes into your FLA file and set required properties in your code.
Page 335 Common workflow for the DataSet component The typical workflow for the DataSet component is as follows. To use a DataSet component: Add an instance of the DataSet component to your application and give it an instance name. Select the Schema tab for the DataSet component and create component properties to represent the persistent fields of the data set.
Page 336 To create an application using the DataSet component: In Flash Professional 8, select File > New. In the Type column, select Flash Document and click OK. Open the Components panel if it’s not already open. Drag a DataSet component from the Components panel to the Stage. In the Property inspector, give it the instance name user_ds.
Page 337: Dataset Class (Flash Professional Only)
To bind the selected index of the DataSet component to the selected index of the DataGrid component, select the DataGrid component on the Stage and click the Add Binding (+) button again in the Component inspector. In the dialog box that appears, select “selectedIndex : Number”. Click OK. Double-click the Bound To field in the Component inspector to open the Bound To dialog box.

Page 501: Chapter 21: Eventdispatcher Class
CHAPTER 21 EventDispatcher class Events let your application know when the user has interacted with a component, and when important changes have occurred in the appearance or life cycle of a component—such as its creation, destruction, or resizing. The methods of the EventDispatcher class let you add and remove event listeners so that your code can react to events appropriately.
Page 502: Eventdispatcher Class (Api)
Some event object properties are defined in the W3C specification (www.w3.org/TR/DOM- Level-3-Events/events.html) but aren’t implemented in version 2 of the Macromedia Component Architecture. Every version 2 event object has the properties listed in the table below. Some events have additional properties defined, and if so, the properties are listed in the event’s entry.

Page 507: Chapter 22: Flvplayback Component
CHAPTER 22 FLVPlayback Component (Flash Professional Only) The FLVPlayback component lets you easily include a video player in your Flash application to play progressively downloaded Flash video (FLV) files over HTTP or play streaming FLV files from a Flash Communication Server (FCS) or from a Flash Video Streaming Service (FVSS).
Page 508 The FLVPlayback component includes the FLV Playback Custom UI components. The FLVPlayback component is a combination of the display area, or video player, in which you view the FLV file and the controls that allow you to operate it. The FLV Playback Custom UI components provide control buttons and mechanisms that you can use to play, stop, pause, and otherwise control the FLV file.
Page 509: Using The Flvplayback Component
The FLVPlayback component also includes an ActionScript application programming interface (API). The API includes the FLVPlayback, VideoError, and VideoPlayer classes. For more information on these classes, see “FLVPlayback class” on page 539, the “VideoPlayer class” on page 706, and the “VideoError class”...

You can use it create an...
Page 512 FLVPlayback component parameters For each instance of the FLVPlayback component, you can set the following parameters in the Component inspector or the Property inspector: autoPlay A Boolean value that determines how to play the FLV file. If , the true component plays the FLV file immediately when it is loaded.
Page 513 isLive A Boolean value that, if , specifies that the FLV file is streaming live from Flash true Communication Server. One example of a live stream is a video of news events as they are taking place. The default value is .
Page 514 Specifying the contentPath parameter parameter lets you specify the name and location of the FLV file, both of contentPath which inform Flash how to play the file. Open the Content Path dialog box by double-clicking the Value cell for the contentPath parameter in the Component inspector.
Page 515: Using Cue Points
You can also specify the name and location of the FLV file using the ActionScript property and the FLVPlayback contentPath FLVPlayback.play() methods. These three alternatives take precedence over the FLVPlayback.load() parameter in the Component inspector. For more information, see contentPath on page 579, on page 620...
Page 516 A navigation cue point allows you to seek to a particular frame in the FLV file because it creates a keyframe within the FLV file as near as possible to the time that you specify. A keyframe is a data segment that occurs between image frames in the FLV file stream. When you seek to a navigation cue point, the component seeks to the keyframe and starts the event.
Page 517 Using the Flash Video Cue Points dialog box Open the Flash Video Cue Points dialog box by double-clicking the Value cell of the parameter in the Component inspector. The dialog box looks like the cuePoints following figure: The dialog box displays embedded and ActionScript cue points. You can use this dialog box to add and delete ActionScript cue points as well as cue point parameters.
Page 518 To add a parameter for the selected cue point, click the plus (+) sign above the Parameters section, and enter values in the Name and Value columns. Repeat this step for each parameter. To add more ActionScript cue points, repeat steps 2 through 5 for each one. Click OK to save your changes.
Page 519 Adding ActionScript cue points You can add ActionScript cue points to an FLV file using the method. The addASCuePoint() following example adds two ActionScript cue points to the FLV file when it is ready to play. It adds the first cue point using a cue point object, which specifies the time, name, and type of the cue point in its properties.
Page 520 event handler in the following example calls the method to find ready findCuePoint() the cue point and then calls the method to find the ASpt1 findNearestCuePoint() navigation cue point that is nearest to the time of cue point ASpt1 import mx.video.*; my_FLVPlybk.contentPath = "http://www.helpexamples.com/flash/video/ cuepoints.flv"...
Page 521 Seeking navigation cue points You can seek to a navigation cue point, seek to the next navigation cue point from a specified time, and seek to the previous navigation cue point from a specified time. The following example plays the FLV file cuepoints.flv and seeks to the cue point at 7.748 when the ready event occurs.
Page 522 You can test whether an embedded FLV file cue point is enabled using the method. The following example disables the embedded cue isFLVCuePointEnabled() points when the video is ready to play. When the first event point2 point3 cuePoint occurs, however, the event handler tests to see if cue point is disabled and, if so, point3 enables it.
Page 523: Playing Multiple Flv Files
Playing multiple FLV files You can play FLV files sequentially in an FLVPlayback instance simply by loading a new URL in the property when the previous FLV file finishes playing. For example, the contentPath following ActionScript code listens for the event, which occurs when an FLV file complete finishes playing.
Page 524 The following ActionScript code loads the property to play an FLV file in the contentPath default video player and adds a cue point for it. When the event occurs, the event ready handler opens a second video player by setting the property to the activeVideoPlayerIndex number 1.
Page 525 my_FLVPlybk.visibleVideoPlayerIndex = 0; // make the 1st player visible my_FLVPlybk.play(); // begin playing the 1st player // add listener for a cuePoint event my_FLVPlybk.addEventListener("cuePoint", listenerObject); listenerObject.complete = function(eventObject:Object):Void { trace("Hit complete event for player: " + eventObject.vp); if (eventObject.vp == 0) { my_FLVPlybk.activeVideoPlayerIndex = 1;...

For more information on administering the Flash Communication Server, including how to set up a live stream, see the FCS documentation at www.macromedia.com/support/ documentation/en/flashcom/. When playing a live stream with FCS, you need to set the FLVPlayback property . For more information, see...
Page 527 Selecting a predesigned skin You can select a skin for the FLVPlayback component by clicking the cell for the value skin parameter in the Component inspector. Then click the magnifying glass icon to open the following Select Skin dialog box, in which you can select a skin or provide a URL that specifies the location of the skin SWF file.
Page 528 To begin, simply drag the FLV Playback Custom UI components that you want from the Components panel, place them where you want them on the Stage, and give each one an instance name in the Property inspector. After your components are on the Stage, you edit them as you would any other symbol.
Page 529 Most of the buttons, as supplied, are based on a common set of movie clips so that you can change the appearance of all the buttons at once. You can use this capability, or you can replace those common clips and make every button look different. BufferingBar component The buffering bar component is simple: It consists of an animation that is made visible when the component enters the buffering state, and it does not require any special ActionScript to...
Page 530 You might notice that the handle movie clip has a rectangle in the background with alpha set to 0. This rectangle increases the size of the handle’s hit area, making it easier to grab without changing its appearance, similar to the hit state of a button. Because the handle is created dynamically at runtime, it must be a movie clip and not a button.
Page 531 Progress and fullness movie clips The SeekBar component has a progress movie clip and the VolumeBar has a fullness movie clip, but in practice, any SeekBar or VolumeBar can have either, neither, or both of these movie clips. They are structurally the same and behave similarly but track different values. A progress movie clip fills up as the FLV file downloads (which is useful for an HTTP download only, because it is always full if streaming from FCS) and a fullness movie clip fills up as the handle moves from left to right.
Page 532 The progress or fullness movie clip is scaled horizontally based on the percentage. At 0%, the instance’s is set to 0, making it invisible. As the percentage grows, the _xscale _xscale adjusted until, at 100%, the clip is the same size it was on the Stage when it was created. Again, this is not necessarily = 100 because the clip instance might have been scaled _xscale...
Page 533 In the Library panel, open the FLVPlayback Skins folder, and then open the SquareButton folder below it. Select the SquareBgDown movie clip, and double-click it to open it on the Stage. Right-click (Windows) or Control-click (Macintosh), select Select All from the menu, and delete the symbol.
Page 534 In the Actions panel on Frame 1 of the Timeline, add an import statement for the video classes, and assign the button and seek bar names to the corresponding FLVPlayback properties, as shown in the following example: import mx.video.*; my_FLVPlybk.stopButton = my_stopbttn; my_FLVPlybk.playPausebttn = my_plypausbttn;...
Page 535 Although layout_mc looks a lot like how the skin will look like at runtime, the contents of this clip are not visible at runtime. It is used only to calculate where to place the controls. The other controls on the Stage will be used at runtime. Within layout_mc is a placeholder for the FLVPlayback component named video_mc.
Page 536 The initial ActionScript code defines the minimum width and height for the skin. The Select Skin dialog box shows these values and they are used at runtime to prevent the skin from scaling below its minimum size. If you do not want to specify a minimum size, leave it as undefined or less than or equal to zero.
Page 537 Button states All the button states are laid out on the Stage, but where these movie clip instances are placed on the Stage is not important. It is important, however, that they are nested within movie clips in a specific way and that every clip instance has the correct instance name. The structure of the clip instances and their instance names are shown in the following example: playpause_mc...
Page 538 Buffering bar The buffering bar has two movie clips: bufferingBar_mc and bufferingBarFill_mc. Each clip’s position on the Stage relative to the other clip is important because this relative positioning is maintained. The buffering bar uses two separate clips because the component scales bufferingBar_mc but not bufferingBarFill_mc.
Page 539 The seekBarProgress_mc clip works without a fill_mc, much like the way a progress_mc clip works in FLV Playback Custom UI Components. In other words, it is not masked and is scaled horizontally. The exact dimensions of the bufferingBarProgress_mc at 100% is defined by left and right margins within the bufferingBar_mc clip.
Page 540 ActionScript The seek bar and volume bar support the following additional properties: Property Description The movie clip for the handle. Defaults to handle_mc:MovieClip seekBarHandle_mc or volumeBarHandle_mc The movie clip for progress. Defaults to progress_mc:MovieClip seekBarProgress_mc or volumeBarProgress_mc. The movie clip for fullness. Defaults to seekBarFullness or fullness_mc:MovieClip volumeBarFullness.

Page 724: Using Focus Manager
FLVPlayback Component (Flash Professional Only)
Page 725 CHAPTER 23 FocusManager class You can use the Focus Manager class to specify the order in which components receive focus when a user presses the Tab key to navigate in an application. You can also use the Focus Manager to set a button in your document that receives keyboard input when a user presses Enter (Windows) or Return (Macintosh).
Page 726 The Focus Manager handles focus changes caused by mouse clicks. If the user clicks a component, that component is given focus. When testing a script using Focus Manager (Control > Test Movie), select Control > Disable Keyboard Shortcuts in test mode; otherwise, Focus Manager does not appear to work.
Page 727: Customizing Focus Manager
To create a button that receives focus when a user presses Enter (Windows) or Return (Macintosh), set the property to the instance name of FocusManager.defaultPushButton the desired button, as shown here: focusManager.defaultPushButton = okButton; The Focus Manager is sensitive to when objects are placed on the Stage (the depth order of objects) and not their relative positions on the Stage.

Page 755: Chapter 26: Label Component
“Name:” label to the left of a TextInput field that accepts a user’s name. If you’re building an application using components based on version 2 of the Macromedia Component Architecture, it’s a good idea to use a Label component instead of a plain text field because you can use styles to maintain a consistent look and feel.
Page 756 Label parameters You can set the following authoring parameters for each Label component instance in the Property inspector or in the Component inspector (Window > Component Inspector menu option): autoSize indicates how the label is sized and aligned to fit the text. The default value is none The parameter can have any of the following four values: , which specifies that the label is not resized or aligned to fit the text.
Page 757: Customizing The Label Component
Creating an application with the Label component The following procedure explains how to add a Label component to an application while authoring. In this example, the label is beside a combo box with dates in a shopping cart application. To create an application with the Label component: Drag a Label component from the Components panel to the Stage.
Page 758 A Label component supports the following styles: Style Theme Description Both The text color. The default value is 0x0B333C for the color Halo theme and blank for the Sample theme. Both The color for text when the component is disabled. The disabledColor default color is 0x848384 (dark gray).
Page 759: Label Class
Label class Inheritance MovieClip > UIObject class > Label ActionScript Class Name mx.controls.Label The properties of the Label class allow you at runtime to specify text for the label, indicate whether the text can be formatted with HTML, and indicate whether the label auto-sizes to fit the text.

Page 765: Chapter 27: List Component
CHAPTER 27 List component The List component is a scrollable single- or multiple-selection list box. A list can also display graphics, including other components. You add the items displayed in the list by using the Values dialog box that appears when you click in the labels or data parameter fields. You can also use the methods to add items to the list.
Page 766 When you design an application with the List component, or any component that extends the List class, it is helpful to understand how the list was designed. The following are some fundamental assumptions and requirements that Macromedia used when developing the List class: Keep it small, fast, and simple.
Page 767 Lists don’t measure text. This restriction has the most potential ramifications. Because a list must scale to thousands of records, any one of which could contain an unusually long string, it shouldn’t grow to fit the largest string of text within it, or add a horizontal scroll bar in “auto”...
Page 768 List parameters You can set the following authoring parameters for each List component instance in the Property inspector or in the Component inspector: data is an array of values that populate the data of the list. The default value is (an empty array).

Page 773 Style Theme Description Both The background color of a selected row. The default selectionDisabledColor value is a 0xDDDDDD (medium gray). Because the default value for this property is the same as the default for , the selection is backgroundDisabledColor not visible when the component is disabled unless one of these style properties is changed.
Page 774: List Class
When creating a new class-level style declaration, you lose all default values provided by the declaration. This includes , which is required for ScrollSelectList backgroundColor supporting mouse events. To create a class-level style declaration and preserve defaults, use a loop to copy the old settings to the new declaration. for..in var source = _global.styles.ScrollSelectList;...
Page 775 A row is a component that is used to display an item. Rows are either supplied by default by the list (the SelectableRow class is used), or you can supply them, usually as a subclass of the SelectableRow class.
