flex动态创建组件并放下
private function newHandler(event:MouseEvent):void{
var e:Element = new Element();
e.addEventListener(MouseEvent.CLICK,mouseClick);
Alert.show(e.width.toString());
}

<mx:Button x="185" y="10" label="New" click="newHandler(event)"/>

我要click后，这个Element能跟着mouse移动，然后mouse click了，就把element放下。
这个功能

有会的朋友指点下

给你做了个实例，你可以参考下

XML code

<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"                layout="absolute" width="100%" height="100%"                mouseMove="mouserMoveHandler(event)"                mouseDown="mouseDownHandler()"                mouseUp="mouseUpHandler()"                >    <mx:Script>        <![CDATA[            private var moveEnabled:Boolean = false;                        private function mouserMoveHandler(event:MouseEvent):void            {                if (moveEnabled) {                    var x:int = event.stageX;                    var y:int = event.stageY;                                        canvas.x = x - canvas.width/2;                    canvas.y = y - canvas.height/2;                }            }                        private function mouseDownHandler():void            {                moveEnabled = true;            }            private function mouseUpHandler():void            {                moveEnabled = false;            }        ]]>    </mx:Script>    <mx:Canvas  id="canvas" backgroundColor="red" width="100" height="100"/></mx:Application>
