flex中实现marquee效果（由下而上滚动）

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
    creationComplete="complete()">
    <mx:Script>
        <![CDATA[
            private function complete():void
            {
                move_up.yFrom = cs.height - 6;    //"加6减6是为了首尾连接更加自然"
                move_up.yTo = 0 - tt.height + 6;  //同上
                move_up.repeatCount = 0; //无限次重复
                move_up.repeatDelay = 0; //重复时间，毫秒
                move_up.duration = 6000; //滚动一次的时间，毫秒
                move_up.play();
            }
           
            private function move_pause():void
            {
                move_up.pause();  //暂停
            }
           
            private function move_resume():void
            {
                move_up.resume(); //从暂停位置开始
            }
        ]]>
    </mx:Script>
    <mx:Move id="move_up" target="{tt}" />
    <mx:Panel width="250" height="200" layout="absolute" title="公告栏"
        fontSize="13" horizontalCenter="0" verticalCenter="0">
        <mx:Canvas id="cs" width="100%" height="100%" left="0" top="0"
            verticalScrollPolicy="off" mouseOver="move_pause()" mouseOut="move_resume()">
            <mx:Text id="tt" width="94%" horizontalCenter="0"
                text="表面上看，文字由下向上滚动，其实是Text控件在滚动。" verticalCenter="0">
            </mx:Text>
        </mx:Canvas>
    </mx:Panel>
</mx:Application>

确实不错！ 我曾用scroll实现过类似效果
