当组件可见属性以编程方式设置为 false 时，不会触发 hideEffect
在 Flex 中，我有一个基于 Canvas 的组件。 它看起来像这样（为了更好地阅读，我删除了
<mx:Canvas verticalScrollPolicy="off" showEffect="showFX" hideEffect="hideFX" horizontalScrollPolicy="off" creationComplete="doComplete()" xmlns:mx="http://www.adobe.com/2006/mxml" width="63" height="63">
<mx:Fade id="hideFX" alphaFrom="1" alphaTo="0" easingFunction="mx.effects.easing.Linear.easeIn" startDelay="0" duration="600" />
<mx:Fade id="showFX" alphaFrom="0" alphaTo="1" easingFunction="mx.effects.easing.Linear.easeIn" startDelay="0" duration="600" />
</mx:Canvas>
如果我将 customComponent.Visible 设置为 false，组件被隐藏（如预期）。但根本不会触发 hideFX。我做错了什么吗？或者这不是使用 hideEffect 和 showEffect 的正确方法？
In Flex I've got a component, which is based on a Canvas.
It looks like this (I removed the <mx:Script> for better reading):
<mx:Canvas verticalScrollPolicy="off" showEffect="showFX" hideEffect="hideFX" horizontalScrollPolicy="off" creationComplete="doComplete()" xmlns:mx="http://www.adobe.com/2006/mxml" width="63" height="63">
<mx:Fade id="hideFX" alphaFrom="1" alphaTo="0" easingFunction="mx.effects.easing.Linear.easeIn" startDelay="0" duration="600" />
<mx:Fade id="showFX" alphaFrom="0" alphaTo="1" easingFunction="mx.effects.easing.Linear.easeIn" startDelay="0" duration="600" />
</mx:Canvas>
If I set customComponent.Visible to false, the component gets hidden (as expected). But doesn't trigger the hideFX at all. Am I doing something wrong? Or isn't this the correct way to use hideEffect and showEffect?
