Can I just use draw2D figures to be dragSources and dropTargets ? How do I
achieve this functionality if I am just using draw2D and NOT using GEF?

Could some one provide me some tips here?

Thanks,
MM

You need to hook the DragSource on the canvas. When you get a dragStart,
determine which figure is under the mouse, and ask that figure if it is a
"lightweight" drag source, and allow the drag if it is. This is very
similar to DelegatingDragSourceAdapter in JFace

I tried doing the same thing but I am not able to find out the figure
under the mouse. I have the following construct.

Figure Canvas
-- Figure
-- Figure1
-- Figure2
-- Figure3

I am currently trying to find out using findFigureAt() but I am sure I
have problems identifying the coordinates at which the figure is. Any
suggestions here. Thanks in advance.
