How to get the length and width of the current window in flex4

In order to implement flex web page adaptive screen size before

The answer I saw online is

Application.application.width

Application.application.height

But this is applicable to <mx:Applicationg/>. After flex4, it is recommended to apply <s:Application/>, and it is found that Application.application no longer exists
this.stage.stageWidth

I made a login interface without using state and made the component PopUp into a new window. This will facilitate repeated use in the future, but I also wanted the new window to look like a new page, so I speculated on how to make the PopUp window The interface size adapts to the screen.

My approach is

<s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns:s="library://ns.adobe.com/flex/spark" 
xmlns:mx="library://ns.adobe.com/flex/mx" 
xmlns:local="*" 
width="1366" height="768" 
preinitialize="loginPreinit()" 
initialize="loginInit()">

private function loginPreinit():void 
{ 
this.width=this.stage.stageWidth; 
this.height=this.stage.stageHeight; 
}

This way the PopUp window also adapts to the screen size.
