復(fù)制代碼 代碼如下:

package
{
import flash.events.Event;

public class MyEvent extends Event
{
public static const myEvent:String="myEvent";

public var data:*;

public function MyEvent(type:String,bubbles:Boolean=false,cancellabel:Boolean=false,data:* = null)
{
super(type,false,false);
this.data = data;
}

override public function clone():Event{
return new MyEvent(myEvent,false,false,data);
}

override public function toString():String{

return formatToString("MyEvent");
}
}
}
