有没有在Flex 4中任何情况下，我可以用它来检测状态更改？

Is there any event in Flex 4 that I can use to detect a state change?

推荐答案

我知道这个问题是旧的，但通过使用Google的状态变化的事件我还是到这里来所以人们想知道：

I know this question is old but by googling for state change events I still get here so for people that want to know:

有一个由组件出动 StateChangeEvent.CURRENT_STATE_CHANGE 事件，这样你的应用程序还可以侦听。

There is a StateChangeEvent.CURRENT_STATE_CHANGE event that is dispatched by the component, so your application can also listen for that.

在你的监听功能，您就可以存取权限的 StateChangeEvent.oldState 和 StateChangeEvent.newState 属性。

In your listener function you can then acces the StateChangeEvent.oldState and StateChangeEvent.newState properties.
