walking with RIA

Flex2中，所有的可视化组件都实现了可拖拽的功能，有部分组件在此基础上进行了扩展。简单应用就可以做出很有趣的效果。

这部分组件包括：List,DataGrid,Menu,TileList,Tree

以下代码就实现了List组件间数据的相互拖拽效果：

<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"
    width="365" height="225"
    creationComplete="creationCompleteHandler();"
>

    <mx:Script>
        <![CDATA[
                private function creationCompleteHandler():void
                {

                    srclist.dataProvider = ["Flex", "Flash", "Red5"];       
                    destlist.dataProvider = [];
                }

        ]]>
    </mx:Script>

    <mx:Panel title="Select activities" layout="horizontal">
        <mx:VBox width="50%">

            <mx:Label text="List 1"/>

            <mx:List
                id="srclist" width="100%" height="100"
                allowMultipleSelection="true"               
                dragEnabled="true"
  dropEnabled="true"
            />

        </mx:VBox>

        <mx:VBox width="50%">
            <mx:Label text="List 2"/>

            <mx:List 
                id="destlist" width="100%" height="100"
                dropEnabled="true"
  dragEnabled="true"
            />

        </mx:VBox>
    </mx:Panel>
</mx:Application>
