GlowInstance

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

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

The GlowInstance class implements the instance class for the Glow effect. Flex creates an instance of this class when it plays a Glow 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 Glow effect, the TweenEvent.value property contains a 4-item Array, where:

value[0]:uint The value of the target's GlowFilter.color property.
value[1]:Number A value between the values of the Glow.alphaFrom and Glow.alphaTo property.
value[2]:Number A value between the values of the Glow.blurXFrom and Glow.blurXTo property.
value[3]:Number A value between the values of the Glow.blurYFrom and Glow.blurYTo property.
