Flash Lite 2.0 is based on Flash Player 7, but differs from it in the following respects: It does not support ActionScript 2.0 (as used with Flash Player 7 for Flash desktop applications). It supports some features only partially. It adds some features specifically for mobile devices. This document describes the differences between the ActionScript supported for Flash Lite 2.0 and the ActionScript that was supported for Flash Player 7. Wherever applicable, this document includes cross-references to the following documents that provide additional details about the various classes and how to use them when writing Flash Lite 2.0 applications: Flash Lite 2.x ActionScript Language Reference Developing Flash Lite 2.x Applications Learning ActionScript 2.0 in Flash Guide to instructional media The Flash Lite documentation package includes the following media to help you learn how to create Flash Lite applications: Getting Started with Flash Lite 2.x provides an overview of Flash Lite technology and developing Flash Lite 2.0 content for mobile devices. It also includes a step-by-step tutorial for creating a Flash Lite 2.0 application. Developing Flash Lite 2.x Applications is a comprehensive guide to creating Flash Lite content and includes instructions for testing your applications in the integrated Flash Lite emulator. Flash Lite 2.x ActionScript Language Reference describes all the ActionScript language features available to Flash Lite developers and provides example code. 5 Learning ActionScript 2.0 in Flash describes how to write ActionScript for Flash Player 7. Cross references in Introduction to Flash Lite 2.x ActionScript detail the sections of Learning ActionScript 2.0 in Flash that apply to Flash Lite. The Flash Lite sample applications demonstrate key concepts and best practices discussed or mentioned in the written documentation.

Flash Lite 2.0 modifies the standard Flash Player 7 commands, and adds commands that are specific to embedded devices. Flash Lite 2.0 also supports the fsCommand2() function, which provides similar functionality to fsCommand(), with the exception that the command is executed immediately, not deferred until after the calling frame is processed. For more information on the fsCommand2() function, see the Flash Lite 2.x ActionScript Language Reference. 7 Commands unsupported and partially supported by fsCommand The following table lists the commands that are unsupported by fsCommand() when using ActionScript 2.0 to create Flash Lite content. Command quit fullscreen Description Closes the projector. Specifying true sets Flash Player to full-screen mode. Specifying false returns the player to normal menu view. Specifying false sets the player so the SWF file is always drawn at its original size and is never scaled. Specifying true forces the SWF file to scale to 100% of the screen. Specifying true enables the full set of context menu items. Specifying false hides all the context menu items except About Flash Player and Settings. Executes an application from within the projector. Specifying true sends all key events, including accelerator keys, to the onClipEvent(keyDown/keyUp) handler in Flash Player. allowscale showmenu exec trapallkeys Commands partially supported or unsupported by fsCommand The following table lists the ActionScript commands, functions, and keywords that are either partially or not supported by Flash Lite 2.0. Command, function, or keyword asfunction fscommand() Description A protocol for URLs in HTML text fields. Function that lets the SWF file communicate with either Flash Player or the program hosting Flash Player, such as a web browser. Prefix for events to execute when the event occurs. Limitation: The supported events are rollout, rollover, and keyPress. Support Not supported Partially supported Partially supported on 8 Unsupported and Partially Supported ActionScript Elements Command, function, or keyword onClipEvent Description Event handler; triggers actions defined for a specific instance of a movie clip. Limitations: Supported events are press, load, unload, enterFrame, keyDown, keyup, and data. The mouseDown, mouseUp, and mouseMove events are supported if either System.capabilities.hasMouse or System.capabilities.hasStylus are set to true. The onUpdate event handler is defined for a live preview used with a component. The print() function targets the movie clip according to the boundaries specified in the parameter. A function that prints the target movie clip as a bitmap. Support Partially supported onUpdate Not supported Not supported print() printAsBitmap() Not supported printAsBitmaNum() A function that prints a level in Flash Player as a Not supported bitmap according to the boundaries specified in the parameter (bmovie, bmax, or bframe). Not supported A function that prints the level in Flash Player according to the boundaries specified in the boundingBox parameter (bmovie, bmax, or bframe). A function that makes the target movie clip draggable while the SWF is playing. Only one movie clip can be dragged at a time. Limitation: Supported if mouse or stylus interface is supported. Partially supported printNum() startDrag() stopDrag() A function that stops the current drag operation. Partially Limitation: Supported if mouse or stylus supported interface is supported. A function that updates the display Not supported (independent of the frames per second set for the SWF file) when you call it in an onClipEvent() handler or as part of a function or method that you pass to setInterval(). updateAfterEvent() Commands partially supported or unsupported by fsCommand 9 Partially supported global properties The following table lists the ActionScript global properties that are partially supported by Flash Lite 2.0. Properties _droptarget Description Support Partially Read-only property that returns the absolute path in supported slash (/) syntax notation of the movie clip instance on which the draggableInstanceName (the name of a movie clip instance that was the target of a startDrag() function was dropped. This property always returns a path that starts with a slash (/). Global property that specifies the level of anti-aliasing applied to the current SWF file. This property can also control bitmap smoothing. Limitation: Flash Lite does not support bitmap smoothing. Partially supported _highquality _url Read-only property that retrieves the URL of the SWF Partially file from which the movie clip was downloaded. supported 10 Unsupported and Partially Supported ActionScript Elements CHAPTER 2 Unsupported and Partially Supported Classes This chapter describes ActionScript 2.0 classes that are either partially or not supported by Flash Lite 2.0.
