侦听 EventDispatcher 的所有事件类型 [英] Listen to all event types of an EventDispatcher

问题描述

在 Flex 中，是否可以监听 IEventDispatcher 对象的所有事件类型?addEventListener 的第一个参数是类型，是一个字符串.在许多情况下，文档并不清楚它会触发什么事件类型.我想附加一个通用侦听器来检查事件.

In Flex, is it possible to listen to all event types of an object that's an IEventDispatcher? addEventListener's first parameter is the type, which is a string. In many cases the documentation is not clear what event type it fires. I'd like to attach a generic listener to inspect the events.

推荐答案

我认为你必须从这个类派生并像这样覆盖 dispatchEvent 方法:

I think you have to derive from this class and override the dispatchEvent method like this:

override public function dispatchEvent(event:Event):Boolean
{
    trace(event.type);
    return super.dispatchEvent(event);
}
