[flexcoders] Drag Drop functionality in Flex/AS3

[zzberthod]

I would like to do drag and drop on panels. To do this, I'm using a
Canvas containing 3 panels like this:
-|
||
|  PANEL 1   |
||
-
-
||
||
|  PANEL 2   |
||
||
-
-
||
||
|  PANEL 3   |
||
||
||
-

The 3 panels are "vertical align" manually.
Using panels on a Canvas, the panels move correctly. I would like that
when we drag a panel, it can't be drop to another.
Thus, we would be able to exchange panel's position without superimposing.

Notice 1: The 3 panels can have a different height
Notice 2: The top would be to be able add more than 3 panels

Have you got an idea how to do this?
Thanks for your help.

Hello,

I try to add Drag Drop functionality on my Flex application.
But I don't know what to do?

Do you know a core function that I can use in Flex/AS3?

Thanks.
