All Implemented Interfaces:

java.io.Serializable

public class AnimationEvent
extends java.awt.AWTEvent

A semantic event which indicates that an Animation-defined action occured. This high-level event is generated by an Animation Object when an action occurs (such as a change in progress). The event is passed to every AnimationListener object that registered to receive such events using the Animation's addAnimationListener method.

The object that implements the AnimationListener interface gets this AnimationEvent when the event occurs. The listener is therefore spared the details of processing individual selection, and can instead process a "meaningful" (semantic) event.
