Hi all………

We often need to toggle between fullscreen and normal screen in our application.
The following code snippet helps you to toggle between these two screens in Adobe AIR or Flex.
Here I am using StageDisplayState class to do both which has “stage.displayState = StageDisplayState.FULL_SCREEN” and ” stage.displayState = StageDisplayState.NORMAL” constants to do this.

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"  applicationComplete="toggleScreen()">
       <mx:Script>
               <![CDATA[
                       import flash.display.StageDisplayState;
                       private function toggleScreen():void{
                               if(fullScreen.selected == true){
                                       this.goFullScreen();
                               } else {
                                       this.exitFullScreen();
                               }
                       }
                       private function goFullScreen():void {
                               stage.displayState = StageDisplayState.FULL_SCREEN;
                       }
                       private function exitFullScreen():void {
                               stage.displayState = StageDisplayState.NORMAL;
                       }
               ]]>
       </mx:Script>
       <mx:CheckBox label="Full Screen" id="fullScreen" click="this.toggleScreen()"
               	               selected="true"  horizontalCenter="0" verticalCenter="0"/>
</mx:WindowedApplication>
