Flex 4 组 showEffect/hideEffect [英] Flex 4 Group showEffect/hideEffect

问题描述

我有一个组，我想在显示和隐藏时执行擦除效果.

I have a Group that I want to do a wipe effect when it shows and hides.

<fx:Declarations>
    <!-- Place non-visual elements (e.g., services, value objects) here -->
    <s:Wipe id="wipeUp" direction="up" duration="2000"/>
    <s:Wipe id="wipeDown" direction="down" duration="2000" startDelay="2000"/>
</fx:Declarations>

<s:Group 
    id="zoomPopup"
    top="-290"
    right="15"
    width="30"
    height="300"
    visible="false" 
    showEffect="{wipeUp}" hideEffect="{wipeDown}">

该组在更改组可见性时被隐藏和显示，但效果没有任何作用.当我将可见性设置为 false 时，它​​需要 4 秒才能隐藏(延迟 + 持续时间)，但同样没有效果.

The group is being hidden and shown on change of the group's visibility, but the effect doesn't do anything. When I set the visibility to false, it takes 4 secs for it to hide (delay+duration), but again, no effect.

推荐答案

在当前版本的 spark 中，效果触发器未得到官方支持.有关更多详细信息，请参阅此线程:Spark 效果:为什么程序代码优于触发器?

Effect triggers are not officially supported in spark in the current release. See this thread for more details: Spark effects: why is procedural code preferred over triggers?
