用EventDispatcher自定义事件

//首先我们要导入EventDispatcher 
import mx.events.EventDispatcher; 

class testEvent extends MovieClip{ 
  function testEvent(){ 
//在构造函数中初始化 
    EventDispatcher.initialize(this); 
  } 
//定义这三个方法 
 function dispatchEvent(){} 
 function addEventListener(){} 
 function removeEventListener(){} 
 function sendOK(){ 
//定义事件onSend 
    var eventObj1:Object = {target:this,type:"onSend"}; 
    dispatchEvent(eventObj1); 
    trace("OK"); 
//定义事件onComplete 
    var eventObj2:Object = {target:this,type:"onComplete"}; 
    dispatchEvent(eventObj2); 
  } 
}
怎么用我们的事件呢？往下看！
新建一个FLA，输入以下代码：
大家还记得UI组建的事件处理函数么，对这个和UI组建的差不多，都是addEventListener和removoeEventListener。
var testObj:testEvent = new testEvent(); 
var eventObj1:Object = new Object(); 
eventObj1.onSend = function(obj){ 
  trace("type:"+obj.type); 
} 
var eventObj2:Object = new Object(); 
eventObj2.onComplete = function(obj){ 
  trace("type:"+obj.type); 
} 
testObj.addEventListener("onSend",eventObj1); 
testObj.addEventListener("onComplete",eventObj2); 
testObj.sendOK();

ok！去定义你的事件吧。
