Flex Examples

The following example shows how you can use the <mx:Sequence /> MXML tag in Flex to create combined effects which execute in order. This example shows how to fade a display object in, pause, and then fade a display object out. Also, the same thing but with a combination of Wipe effects.

Full code after the jump.
