实现代码如下：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:TitleWindow x="113" y="62" width="337" height="263" layout="absolute" id="titleTest" title="单个控件全屏测试">
<mx:VideoDisplay x="0" y="53" height="160" width="317" id="videoDisplay"/>
<mx:Button x="134.5" y="98" label="全屏" id="btnFullScreen" click="fullScreen();" color="#F41131"/>
<mx:Button x="134.5" y="10" label="全屏" id="btnFullScreen0" click="fullScreen();" color="#F41131"/>
</mx:TitleWindow>
<mx:Script>
<!--[CDATA[
//
import com.util.fullscreen.FullScreenUtil;
private function fullScreen():void{
if(FullScreenUtil.isFullScreen){
btnFullScreen.label = '全屏!';
FullScreenUtil.exitFullScreen();
}else{
btnFullScreen.label = '退出全屏!';
FullScreenUtil.goFullScreen();
// 加入要全屏的对像．videoDisplay
FullScreenUtil.addChild(videoDisplay, true, true, true);
// 将 btnFullScreen 放在全屏对像上．
FullScreenUtil.addChild(btnFullScreen, true, true, false, -1, -1, -1, 100);
}
}
]]-->
</mx:Script>
</mx:Application>
