Hello,
I cannot manage to have Drag and Drop with operation DND.DND_COPY working in RAP.
operation DND.DND_MOVE is working fine but if I do something like this:
getTreeViewer().addDragSupport(DND.DROP_COPY, transferTypes, new MyDragListener());
getAnotherViewer.addDropSupport(DND.DROP_COPY | DROP_MOVE, transfertTypes, new MyDropListener());
I cannot drag and drop something because the event is always DND.DROP_NONE
by debugging I see that in org.eclipse.swt.internal.widgets.displaykit.DNDSupport.readOperationParam(NotifyOperation)
value is always "none" unless I set DND.DROP_MOVE instead of DND.DROP_COPY in getTreeViewer().addDragSupport (in this case it is "move")
is it possible to use other operation like link and copy in RAP or move is the only operation suppored ?
By the way, I cannot use this forum anymore with chromium (login fails), i need to use firefox.
Best regards.
Arnaud

Hi.
You have to either press CTRL to switch to COPY, or set the detail field
of the DropTarget event.
Greetings,
Tim
