Hi,

I want to implement a specific drag and drop process and I wonder which is
the best way to do it.

In my main composite, I have a few child composites aligned vertically
representating commands to send to the server. Moreover, the order of
these commands is important.

Users should have the possibility to move / duplicate a command within
this list (stored in a List instance). So the drag source is also the drop
target.

For example, suppose the current list of commands contains 3 commands (n1,
n2 and n3), the user may want to :

- move n3 between n1 and n2,
- duplicate n2 and place it before n1

to send the following list of commands:

n2, n1, n3, n2

What kind of Transfer class should I use ?
Thanks,
