Flex Label控件竖排显示文字的实现代码

private function rotationtext(event:flexevent):void{
var text:string = event.currenttarget.text;
var length:int = text.length;
var newtext:string = "";
for(var i:int = 0; i < length; i++)
{
newtext+=text.charat(i)+"\r";
}
label.text = newtext;
}

<s:label id="label" text="我是k" x="100" y="40" initialize="rotationtext(event)"/>

不解释了
