聆听自定义事件

Question

当我点击它时，我有一个按钮，一个popoup节目并要求确认。当它确认后，我派遣和自定义事件。但在应用程序中，我无法听到事件？有人可以帮助我吗？

另外它是一个移动应用程序。

首先查看

<fx:Script> 
    <![CDATA[ 
     import events.ConfirmDeleteEvent; 

     import mx.managers.PopUpManager; 

     private var _confirmDeletePopup:ConfirmDeletePopup; 

     protected function confirm(event:MouseEvent):void 
     { 
       this.addEventListener(ConfirmDeleteEvent.YES, deleteConfirm); 
       this.addEventListener(ConfirmDeleteEvent.NO, deleteNotConfirm); 

       _confirmDeletePopup = new ConfirmDeletePopup(); 

       PopUpManager.addPopUp(_confirmDeletePopup, this, true); 
       PopUpManager.centerPopUp(_confirmDeletePopup); 
     } 

     protected function deleteConfirm():void 
     { 
      trace("delete confirm"); 
      lbl.text = "Delete"; 
      PopUpManager.removePopUp(_confirmDeletePopup); 
     } 

     protected function deleteNotConfirm():void 
     { 
      trace("delete not confirm"); 
      lbl.text = "Don't delete"; 
      PopUpManager.removePopUp(_confirmDeletePopup); 
     } 
    ]]> 
</fx:Script> 

<s:Button width="100%" label="Delete" click="confirm(event)"/> 
<s:Label id="lbl" width="100%" fontSize="36" text="What to do?" textAlign="center"/> 

在PopopUp

<fx:Script> 
    <![CDATA[ 
     import events.ConfirmDeleteEvent; 

     import mx.managers.PopUpManager; 

     protected function click(type:String):void 
     { 
      var confirmDeleteEvent:ConfirmDeleteEvent = new ConfirmDeleteEvent(type); 
      var result:Boolean = dispatchEvent(confirmDeleteEvent); 
      trace("Event dispatch : " + result); 
     } 

    ]]> 
</fx:Script> 
<s:VGroup paddingBottom="8" paddingLeft="8" paddingRight="8" paddingTop="8" width="100%"> 
    <s:Label width="100%" maxDisplayedLines="5" 
      text="Delete?" 
      textAlign="center"/> 
    <s:HGroup width="100%"> 
     <s:Button id="yesButton" width="50%" label="Yes" click="click(ConfirmDeleteEvent.YES)"/> 
     <s:Button id="noButton" width="50%" label="No" click="click(ConfirmDeleteEvent.NO)"/> 
    </s:HGroup> 
</s:VGroup> 

我的活动组件使用 package events { import flash.events.Event;

public class ConfirmDeleteEvent extends Event 
{ 
    public static var YES:String = "yes"; 
    public static var NO:String = "no"; 

    public function ConfirmDeleteEvent(type:String, bubbles:Boolean=false, cancelable:Boolean=false) 
    { 
     super(type, bubbles, cancelable); 
    } 

    override public function clone():Event 
    { 
     return new ConfirmDeleteEvent(type, bubbles, cancelable); 
    } 
} 

}

谢谢

添加事件侦听器，您_confirmDeletePopup组件，而不是调用组件。像这样：

protected function confirm(event:MouseEvent):void 
     { 
       _confirmDeletePopup = new ConfirmDeletePopup(); 

       _confirmDeletePopup.addEventListener(ConfirmDeleteEvent.YES, deleteConfirm); 
       _confirmDeletePopup.addEventListener(ConfirmDeleteEvent.NO, deleteNotConfirm); 

       PopUpManager.addPopUp(_confirmDeletePopup, this, true); 
       PopUpManager.centerPopUp(_confirmDeletePopup); 
     }
