flex4 给Group增加边框

转载自：http://www.java2s.com/Code/Flex/Style/DrawaborderaroundaVGroupthatcontainsButtoncontrolswithoutusingacustomskinclass.htm

实例代码如下：

<!--Draw a border around a VGroup that contains Button controls without using a custom skin class--><s:Group><!-- border/background graphics --><s:Rect width="100%" height="100%"><s:stroke><s:SolidColorStroke color="0x000000" weight="2" /></s:stroke></s:Rect><!-- content of container --><s:VGroup left="10" top="10" right="10" bottom="10"><s:Button label="Click Me" /><s:Button label="Click Me" /></s:VGroup></s:Group>

还可以使用 BorderContainer 包围 group。

<s:BorderContainer right="20" top="10" backgroundAlpha="0"><s:Group>....</s:Group></s:BorderContainer>
