I have the same problem, I want to use GEF in a dialog, but I found no way

The only way I am thinking about would be to subclass the FigureCanvas and
add all the stuff present in the GraphicalViewerImpl class which extends
AbstractEditPartViewer and implements GraphicalViewer...
Pretty heavy stuff for me (I don't know GEF yet, I only know draw2D)

I think I found a way:
Just use the ScrollingGraphicalViewer which seems to be done for that (it
takes a parent composite and instanciate a FigureCanvas)

I think "design surface" was interpreted as the outer-most element.

Sure, lot's of people have asked for a figure that is a proxy to an SWT
Control. The lifecycle of the control would probably be managed outside of
the figure, such as by the editpart or something.

Yuck. I don't think there is a generic way to extract the properties from a
Control when calling dispose. We would have to assume the control is around
the whole time.
Direct manipulation of heavyweight contrls would be too painful. You can't
paint on top of them, so there would be no handles or feedback.
