RE: [flexcoders] Re: A big problem for a big beginner (drag'ndrop with create child)

I just realized this is something that was done in the Flex Store sample, if you have the Flex samples installed, you should be able to find the necessary code in there.
 
Otherwise I found this in FlexCoders archive (Manish was there again ;)) : http://www.mail-archive.com/[email protected]/msg07873.html
 
Couldn't resist to give it a try with an image, here's the updated code (you need to specify your own images in the dataProvider >> img):
 
1°) index.mxml
--------------
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
  xmlns="*" backgroundColor="white">
  <MyTree id="myTree" dragEnabled="true">
    <dataProvider>
      <mx:Array>
        <mx:Object label="foo" img="icon.jpg" />
        <mx:Object label="bar" img="icon2.jpg"/>
      </mx:Array>
    </dataProvider>
  </MyTree>
</mx:Application>
 
2°) MyTree.as
------------
class MyTree extends mx.controls.Tree
{
      function get dragImage()
      {
            return MyDragProxy;
      }
}
 
3°) MyDragProxy.as
-------------------
class MyDragProxy extends mx.controls.listclasses.DragProxy
{
 public function createChildren():Void
 {
  super.createChildren();
  var target = mx.core.Application.application.myTree;
  var myImg = target.selectedNode.backingObject.img;
  var myLabel = target.selectedNode.backingObject.label;
  var label = createClassObject(mx.controls.Label, "zeLabel", getNextHighestDepth(), {text: myLabel, y:20});
  var myImg = createClassObject(mx.controls.Image, "zeImage", getNextHighestDepth(), {source: myImg, y:40})
 
 }
}

I think you should investigate the dragProxy class

I want to make a copy of the image in order to move this copy on the
container representing the planning and to keep the image in the list
of the activities.

I know that i need to develop solution with createchild or
createclassobject to do this but i don't succeed.
