Does it exist a way to extend drag possibilities of Navigator view? I'd like to be able to drag a project from Navigator to my View. I can drag folders or files, but can't drag projects. Thank you in advance for any help.

Any idea? I've browsed the code a bit and found in org.eclipse.ui.views.navigator.NavigatorDragAdapter.dragStart(DragSourceEvent):

            if (!(next instanceof IFile || next instanceof IFolder)) {
                event.doit = false;
                return;
            }

So I would need to override the drag behaviour, but it is impossible as when trying to add the dragSupport to an element, that has it, ERROR_CANNOT_INIT_DRAG is thrown (unable to initiate drag source; this will occur if more than one drag source is created for a control ...)
