Handling button events
You can use buttons to quickly add interactivity to your Flash Lite applications. Flash Lite supports the same button events as Flash Player on desktop computers, although some events (for example, onDragOut) are only available on devices that have a mouse or stylus interface. On devices that have a keypad interface only, a button must have keypad focus before it will generate any events.
Flash Lite supports the following ActionScript button events:
|
