what’s the difference between the following two type:  
1.  
var sprite:Test=new Test();  
sprite.addEventListener(“EventType”,\_onAction);  
//…in the main class  
private function \_onAction(e:Event):void{  
//use the event dispatched in the sprite object.  
//get nothing,whether i changed these eventflow parameters anyway.why can’t receive the event???  
}  
2.  
public class Test extends Sprite  
{  
public function Test(){  
dispatchEvent(new Event(“EventType”));

```
                   addEventListener("EventType",_onAction);
               }
               private function _onAction(e:Event):void{
                   //the event is received.
              }
```
