apache-flex - Flex 4 - 当容器的子级依赖于状态时如何循环它们

Question

Flex 的新状态重新设置了标有 includeIn/excludeFrom 的视觉项目的父级。如果我有一个包含 5 个受状态控制的子元素/元素的组 (MainGroup)，是否还有办法获取对 MainGroup 子元素的引用？ mainGroup.numChildren 和 mainGroup.numElements 不起作用，因为子级被重新设置了父级。最好的情况下，它们显示 1。

<s:states>
   <s:State name="view1State" />
   <s:State name="view2State" />
   <s:State name="view3State" />
   <s:State name="view4State" />
</s:states>

<s:Group id="mainGroup">
    <shipping:OrderShipping id="view1"
            includeIn="view1State" />
    <payment:OrderPayment id="view2"
            includeIn="view2State" />
    <verification:OrderVerification id="view3"
            includeIn="view3State" />
    <confirmation:OrderConfirmation id="view4"
            includeIn="view4State" />
</s:Group>

Answer 1

如果你想让状态控制visible/includeinlayout而不是parenthood，就这样做

<s:states>
    <s:State name="view1State" />
    <s:State name="view2State" />
    <s:State name="view3State" />
    <s:State name="view4State" />
</s:states>
<s:Group id="mainGroup">
    <shipping:OrderShipping id="view1" 
        visible="false" 
        includeInLayout="false" 
        visible.view1State="true" 
        includeInLayout.view1State="true"/>
    <payment:OrderPayment id="view2" 
        visible="false" 
        includeInLayout="false" 
        visible.view2State="true" 
        includeInLayout.view2State="true"/>
    <verification:OrderVerification id="view3" 
        visible="false" 
        includeInLayout="false" 
        visible.view3State="true" 
        includeInLayout.view3State="true" />
    <confirmation:OrderConfirmation id="view4" 
        visible="false" 
        includeInLayout="false"
        visible.view4State="true" 
        includeInLayout.view4State="true"/>
</s:Group>
