在网上查了一会，用常用的自定义事件的方式，有时候进行传参、监听和发送貌似不成功。所自己找了一些资料，自己写了一个自定义的事件，直接使用自身的DispatchEvent和监听addeventlistener 个人感觉方便多。在这里显丑了。

package Event
{
	import flash.events.Event;
	
	import mx.controls.Button;
	
	public class PublicEvent extends Event
	{
		private var _data:Object;
		public static const PUBLIC:String="public";
		private static var _cancelable:Boolean = false;
		private static var submit:Button=new Button();
		public function PublicEvent(type:String, data:Object=null, cancelable:Boolean=false)
		{
			//TODO: implement function
			super(type);
			_data = data;
			_cancelable = cancelable;
		}
		public override function clone():Event{
			return new PublicEvent(this.type,this.data,this.cancelable);
		}
		public function get data():Object
		{
			return _data;
		}
		
		public function set data(value:Object):void
		{
			_data = value;
		}
		
		public static function get cancelable():Boolean
		{
			return _cancelable;
		}
		
		public static function set cancelable(value:Boolean):void
		{
			_cancelable = value;
		}
		public static function dispatch(type:String,data:Object=null,cancelable:Boolean=false):Boolean{
			
			return submit.dispatchEvent(new PublicEvent(type,data,cancelable));
		}
		public static function addListener(type:String,listener:Function,useCapture:Boolean=false,priority:int=0,useWeakReference:Boolean=false):void{
			submit.addEventListener(type,listener,useCapture,priority,useWeakReference);
		}
	}
}

这不管是组件之间，还是组件与模块、主程序之间都可以进行通信与传参。
