Flex Event中属性currentTarget与target的区别

- 官方解释　currentTarget是事件的处理对象（event processor）　target是事件的调用对象（event dispatcher）
- 本人解释　currentTarget就是谁addEventListner了就是谁（不会改变）　target则是谁触发了事件就是谁（看情况改变）?- 请看下面的例子<?xml version="1.0" encoding="utf-8"?><s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"??? xmlns:s="library://ns.adobe.com/flex/spark"><fx:Script><![CDATA[import mx.controls.Alert;private function init(): void {this.addEventListener(MouseEvent.CLICK, clickHandler);}private function clickHandler(e:MouseEvent): void {Alert.show("target: " + e.target + "\ncurrentTarget: " + e.currentTarget);}]]></fx:Script><s:Button id="btn1" label="按钮1"/><s:Button id="btn2" label="按钮2" click="clickHandler(event)"/></s:Application>?P.S.点击btn1时currentTarget是application，target是btn1。点击btn2时currentTarget是bt2，target是btn2。
