mx.effects.effectClasses.AnimatePropertyInstance - Adobe® Flex® 4 Language Reference (Flex 4)

Package	mx.effects.effectClasses
Class	public class AnimatePropertyInstance
Inheritance	AnimatePropertyInstance TweenEffectInstance EffectInstance EventDispatcher Object

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The AnimatePropertyInstance class implements the instance class for the AnimateProperty effect. Flex creates an instance of this class when it plays an AnimateProperty effect; you do not create one yourself.

Every effect class that is a subclass of the TweenEffect class supports the following events:

tweenEnd: Dispatched when the tween effect ends.
tweenUpdate: Dispatched every time a TweenEffect class calculates a new value.

The event object passed to the event listener for these events is of type TweenEvent. The TweenEvent class defines the property value, which contains the tween value calculated by the effect. For the AnimateProperty effect, the TweenEvent.value property contains a Number between the values of the AnimateProperty.fromValue and AnimateProperty.toValue properties, for the target property specified by AnimateProperty.property.
