Actionscript 3 如何响应在视图堆栈中选择的NavigatorContent

我的应用程序中有如下视图堆栈：

<mx:ViewStack id="viewStack" left="0" right="0" top="0" bottom="0">
    <views:LoginView top="0" bottom="0" right="0" left="0" id="loginView"/>
    <views:MainHomeView top="0" bottom="0" right="0" left="0" id="childSelectionView"/>
    <views:MainHomeView top="0" bottom="0" right="0" left="0" id="mainEvalView"/>
</mx:ViewStack>

我知道所有NavigatorComponent都会在应用程序启动时分派creationComplete事件，但它们的子节点尚未创建。我是如何回应被选中的孩子转变成自我的？

有时候，在你之前的问题确实在同一个问题域中，稍微多讨论一下是值得的。使用FlexEvent.CONTENT\u CREATION\u COMPLETE事件

我认为你不理解这个问题@迈克。佩蒂74回答得对。
