双向拖放功能

你可以允许双向拖放，通过把两个列表的dragEnabled和dropEnabled属性都设置为true。就像下边：

<!-- Both drag initiator and drop target -->
<mx:List
    id="srclist" width="100%" height="100"
    allowMultipleSelection="true"               
    dragEnabled="true"

    dropEnabled="true"
    dragMoveEnabled="true"
/>

<!-- . . . -->

<!-- Both drag initiator and drop target -->
<mx:List
    id="destlist" width="100%" height="100"
    allowMultipleSelection="true"               
    dragEnabled="true"

    dropEnabled="true"
    dragMoveEnabled="true"
/>
