Hello,
How to Drag an Image A on the Image B.
The image A replace the image B.
And the image B come to replace the image A automatically. (There is a
swapping).
I use DragDropHandler and dragEnterHandler.
Thank you,
Christophe,

I believe you're going to need to handle the drop events yourself and not
use the dropEnabled=true setting. When you do that, by default drop is
denied and you have to tell it to allow it, like in the dragEnter event.
For example:
private function dragEnterHandler(e:DragEvent):void
{
DragManage
I am trying to implement drag and drop onto a tree. In the dropDrop
handler, I want to be able to deny the drop from happening, based on
which element of the tree is being dropped on.
// r is the visible index in the tree
var dropTarget:Tree = Tree(event.currentTarget);
var r:int = dropTarg

How do you mark a drag/drop operation as having a certain type (ie
Move)?

I'm fairly certain that there's no voodoo to automatically delete nodes
from your XML, you need to do that yourself in your drop handler.

For instance

Tree is buggy in Flex 2. If you can, get on the beta for Flex 3 and see
if you still have problems there.

here's my problem:
my current app basically deals with folders and files, such that a
folder has files and a folder can have another folder (that has files
or other folders... you get the idea)
Which line is is breaking on? What's the stack trace look like?

Definitely not, width and height of the image is under 1000px so i guess

Still doesn't work, would it be too much to ask you to post that code to draw

Sorry, try BitmapAsset instead of Bitmap, which extends Bitmap and
implements IFlexDisplayObject. If that doesn't work, I have code to draw
the bitmap data onto a UIComponent.

I followed your advice Dan and used this code:
public function dragItSubs(event:MouseEvent):void{
// Get the drag initiator component from the event object.
var dragInitiator:UIComponent = event.currentTarget as UIComponent;
/
var target:U
Thank you very much for your help, i'll try that and let you know how did it
go.
best regards

You can drag-drop anything.
var dragItems = event.dragSource.dataForFormat("items");
and dragItems is
