Description Yoav Rubin CLA 2003-10-07 11:20:46 EDT 
I have a tree viewer, and some of the editparts in it are non-draggable. When 
the user selects one of them and starts dragging it, there's a drag feedback 
and the cursor changes to a dragging crsor.

I realize there is a problem.  A workaround might be to add an additional 
DragSourceListener which comes at the END of the list of listeners.  See 
AbstractEditPartViewer#hookDragSource(..) for where you could add an additional 
listener.

Then, your listener would simple set the drag to NONE based on the currently 
selected editparts. Doing this will abort the drag completely.
