You use the itemsChangeEffect
style property to apply
this effect to a List control. The default value of
the itemsChangeEffect
style property is undefined
,
meaning it does not use any effect.
Because the DefaultListEffect effect grows and shrinks item renderers as it plays,
you must set the List.variableRowHeight
property to true
to enable the List control to dynalically change its row height.
The <mx:DefaultListEffect> tag inherits all the members of its parent and adds the following members:
<DefaultListEffect Properties color="0xFFFFFF" fadeInDuration="300" fadeOutDuration="300" growDuration="300" removedElementOffset="100" shrinkDuration="300" />

addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void

| Effect | ||
Captures the current values of the relevant properties
on the effect's targets. | Effect | ||
Creates a single effect instance and initializes it. | Effect | ||
Takes an Array of target objects and invokes the
