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。当它确认时，我发送和自定义事件。但在应用程序中我无法听取事件？有人可以帮帮我吗？

这也是一个移动应用程序。

我的活动 <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>

package events { import flash.events.Event;

将事件侦听器添加到_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);
        }
