Flash as3教程：OutDisplay类

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;
//保存侦听类型
private var type:String;
//保存侦听范围
private var dis:DisplayObject;

//构造函数
public function OutDisplay(_type:String,_dis:DisplayObject,...objs){
type = _type;
objAr = objs;
dis = _dis;
dis.addEventListener(_type,fun);
}

//事件处理
private function fun(e:Event):void{
for(var i:uint = 0;i<objAr.length;i ){
if(e.target == objAr[i]) return;
if(objAr[i] is DisplayObjectContainer){
if(objAr[i].contains(e.target)) return;
}
}
dis.removeEventListener(type,fun);
dispatchEvent(new Event(Event.CANCEL));
}

//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{
return objAr;
}

//卸载
public function clear(isDispatch:Boolean = false):void{
if(isDispatch) dispatchEvent(new Event(Event.CANCEL));
dis.removeEventListener(type,fun);
objAr = null;
}

}
}
