带参数的EventDispatcher

//首先  先写一个自定义的EventDisplay的类 继承Event
package gameCode.ui.SecondLayer.onlinePlayer
{
	import flash.events.Event;
	
	public class OnlineEventDisplay extends Event
	{
		//需要监听的类
		static public const WANJIA_ITEM_CLICK:String="WANJIA_ITEM_CLICK";
	 	
		//我有3个事件需要派发 所以就写了3个常量
		static public const WANJIA_SILIAO_ITEM_CLICK:String="WanJia_SiLiao_ITEM_CLICK";
		
		static public const WANJIA_ADD_ITEM_CLICK:String="WanJia_Add_ITEM_CLICK";
		
		static public const WANJIA_ZUDUI_ITEM_CLICK:String="WanJia_ZuDui_ITEM_CLICK";
		
		//这里是用来传入我用来判断的类别 
		public var leibie:String="";
		
		
		//这个data是用来传入你想传入的参数
		public var data:Object;
		
		
		//注意 这里需要把冒泡设为true;
		public function OnlineEventDisplay(type:String, bubbles:Boolean=true, cancelable:Boolean=true)
		{
			super(type, bubbles, cancelable);
		}
		
		//复写clone方法 把data内的数据放入事件内置的data里
		override public function clone():Event
		{
			var e:OnlineEventDisplay=new OnlineEventDisplay(type,bubbles,cancelable);
			e.data=this.data;
			return e;
		}
		
	}
}
