<?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[ private function startMove(event:Event):void{ Sprite(event.target).startDrag(); } private function stopMove(event:Event):void{ Sprite(event.target).stopDrag(); } ]]> </fx:Script> <fx:Declarations> <!-- 将非可视元素（例如服务、值对象）放在此处 --> </fx:Declarations> <mx:Button id="btn" mouseDown="startMove(event)" mouseUp="stopMove(event)" label="move"/> </s:Application> |
如果需要拖动的时候多个控件可以一起拖动，可以先用BorderContainer组件先把控件包含进来
