Hi!
Could you suggest - how do I DnD an element from treeviewer (other than
ecore model) GMF editor?

Hi! Anthony,
Could you please tell - where this dnd handler is implemented?

Hi Manoj
At a high level, Drag and Drop in Eclipse requires DragSourceListener and
DropTargetListener, both in SWT.
Bring up the class hiearchy for these two interfaces to find the GMF classes
that implement them.
Look in the packages and plug-ins where these classes exist.
Done, you have found the DND implementation in the GMF Runtime.
Let us know if this does not help.
Cheers...
Anthony

Hi! Anthony,
I tried it by implementing TransferDropTargetListener.
While dragging the element from treeviewer, I can see it working(using
Systrace), but can not drop the element in editpart.
Could you please provide some link of code snippet?
Regards,
Manoj

Hi!
Have you found any example kind?
I have implemented AbstractDropTargetListener to my editor. Using whicth
I can see the handleDrop() responding.
Also I Habe implemented DragDropEditPolicy on editpart,
but while dropping on editpart it not listening.
On drop, I want to create a chile element on it.
Regards,
Manoj

i have tried it ,just ad i tried with the taipan example,when the original
model is deleted,the droped model does not exist too!that is the
problem!maybe it is easy to make it when the model to be dropped is a
simple one,but when it is very complex,how to make a full deep copy of
it(them)?
thanks for you answer in advance
