Flex Label控件竖排显示文字

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，，，
