自定义事件类的方法──实现接口

================Main文档类================package {import flash.display.Sprite;public class Main extends Sprite {public function Main():void {var a:MyEventObject=new MyEventObject();a.addEventListener(MouseEvent.CLICK,an);function an(evt:MouseEvent) {//代码行，此处省略}}}}================MyEventObject发送事件类================package {import flash.events.Event;import flash.events.EventDispatcher;import flash.events.IEventDispatcher;public class MyEventObject extends IEventDispatcher {private var abc:EventDispatcher;public function MyEventObject():void {abc=new EventDispatcher(this);//复合EventDispatcher类}//重写IEventDispatcher接口的5个方法，这里只列举2个public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void {abc.addEventListener(type, listener, useCapture, priority, useWeakReference);}public function dispatchEvent(evt:Event):void {return abc.dispatchEvent(evt);}}}
