Hi,

i want to implement some kind of desktop, using GEF. While implementing, i
got aware of a
problem, i cannot solve.

The desktop needs to handle both operations coexistently. That means drag-
as well as drop-operations.

I want to be able to drag some resources FROM a JFace treeviewer TO the
desktop and drag
resources FROM the same desktop back TO other SWT widgets. I also move
resources on
the desktop in the "normal" way.

When i register both dnd-handlers on the same viewer, i can no longer move
resources on the desktop
itself, because every mouse gesture leads to a drag&drop-operation.

Has anyone ever solved a problem like this? I would appreciate some hints or
workarrounds.
Would be a pity, if GEF does
