[flexcoders] Using a drag proxy

2005-05-26 Thread digital_eyezed 
Hi,

I have a fully functioning drag and drop operation going on. All I 
want to do is add an image using the drag proxy functionality to the 
application.

Here is the tree I drag from:

mx:Tree id=tree1 dataProvider={MyService.result} width=100% 
height=100% dragEnabled=true/

And here is the List I drag to:

mx:List id=theList width=150 height=25 dragEnter=doDragEnter
(event) dragExit=doDragExit(event); dragOver=doDragOver(event); 
dragDrop=doDragDrop(event)/

Where do I put the code to add the drag Proxy? I have already 
embedded an image (image1) in my actionscript and want to allow that 
image to show, with an offset (which is coded to offsetX and 
offsetY) of 0 and no initialization paramaters.

Normally I would have thought that creating a mouseDown even on the 
tree would enable me to create a dragsource and doDrag method but 
this seems to screw up the rest of the drag operation as it is 
mostly handled in the doDragDrop(event)(and it completely froze IE6).

Thanks in advance for any help!

Iain

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()
