Air 屏蔽关闭事件，自定义关闭并加处理。

 

1. 为WindowedApplication添加关闭事件

    <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                       xmlns:s="library://ns.adobe.com/flex/spark"
                       xmlns:mx="library://ns.adobe.com/flex/mx"
                       closing="windowedapplication1_closingHandler(event)"
                       creationComplete="init(event)">

2. 取消事件执行并提示是否确认关闭

    protected function windowedapplication1_closingHandler(event:Event):void
    {
                event.preventDefault();

                Alert.show("您确定要关闭窗口吗？","关闭窗口提示",Alert.YES|Alert.NO,this,windowsCloseHandler);
    }

3. 关闭窗口

private function windowsCloseHandler(event:CloseEvent):void

{
                event.detail==Alert.YES?stage.nativeWindow.close():null;
}

 

非常简单
