You can do it by making your own drag proxy.
See example below.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
xmlns="*"
backgroundColor="white">
<MyTree dragEnabled="true">
<dataProvider>
<mx:Array>
<mx:Object label="foo" />
<mx:Object label="bar" />
</mx:Array>
</dataProvider>
</MyTree>
</mx:Application>
// MyTree.as
class MyTree extends mx.controls.Tree
{
function get
dragImage()
{
return MyDragProxy;
}
}
//MyDragProxy.as
class MyDragProxy extends
mx.controls.listclasses.DragProxy
{
public function
createChildren():Void
{
super.createChildren();
var label = createClassObject(mx.controls.Label,
"",
getNextHighestDepth(), {text: "Watch me
move"});
label.y += 20;
}
}
You can put your image in createChildren()
