今天在adobe网站上无意中看到flex2.0可以不用javascript就可以简单的实现全屏

顺手记录下来供大家参考：

                this.goFullScreen();
            } else {
                this.exitFullScreen();
            }
        }
       
        private function goFullScreen():void {

        private function exitFullScreen():void {
               stage.displayState = StageDisplayState.NORMAL;
