3、Flex全屏方式
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init();"><mx:Script><![CDATA[import mx.controls.Alert;private function init():void{this.btn.dispatchEvent(new MouseEvent(MouseEvent.CLICK));}private function fullScreen(event:Event):void{Alert.show("btn clicked");if(stage.displayState == StageDisplayState.FULL_SCREEN){stage.displayState = StageDisplayState.NORMAL;btn.label = "FullScreen";}else{stage.displayState=StageDisplayState.FULL_SCREEN;btn.label = "normalScreen";}}]]></mx:Script><mx:VBox><mx:Label text="Hello World"/><mx:Button id="btn" label="FullScreen" click="fullScreen(event);"/></mx:VBox></mx:Application>?这里写完可能不能全屏，那么就要修改工程里html-template文件夹下的index.template.html文件
