Flash as3教程：OutDisplay类

CODE:
import index.base.func.OutDisplay;

var menu:Menu = new Menu;
menu.mc1.addEventListener(MouseEvent.MOUSE_OVER,mouseOverFun);
menu.mc2.addEventListener(MouseEvent.MOUSE_OVER,mouseOverFun);
menu.mc3.addEventListener(MouseEvent.MOUSE_OVER,mouseOverFun);
menu.mc4.addEventListener(MouseEvent.MOUSE_OVER,mouseOverFun);
addChild(menu);

function mouseOverFun(e:MouseEvent){
var m:Menu = new Menu;
m.x = e.currentTarget.x e.currentTarget.parent.x;
m.y = e.currentTarget.y e.currentTarget.parent.y;
addChild(m);

var out:OutDisplay = new OutDisplay(MouseEvent.MOUSE_OVER,stage,e.currentTarget);
out.addEventListener(Event.CANCEL,cancelFun);
out.add(m);

m = null;
out = null;
}

function cancelFun(e:Event):void{
var out:OutDisplay = e.currentTarget as OutDisplay;
var tmpAr:Array = out.objects;
removeChild(tmpAr[1]);
out.removeEventListener(Event.CANCEL,cancelFun);

tmpAr = null;
out = null;
}类的源代码：

CODE:
package index.base.func{

import flash.display.DisplayObject;
import flash.display.DisplayObjectContainer;
import flash.events.Event;
import flash.events.EventDispatcher;

public class OutDisplay extends EventDispatcher{

//保存所有对象
private var objAr:Array;

//构造函数
public function OutDisplay(_type:String,_dis:DisplayObject,...objs){

}

//事件处理
private function fun(e:Event):void{

}
}
dis.removeEventListener(type,fun);

}

//添加对象
public function add(...objs):Array{
for(var i:int = 0; i < objs.length; i ){
objAr.push(objs[i]);
}
return objects;
}

//获取对象列表
public function get objects():Array{

//卸载
public function clear(isDispatch:Boolean = false):void{
