I have a multipage editor, with one page displaying text and the other page
displying it's graphical representation. When a user makes a change to the
text, I need to update the diagram as well - since It isn't very easy to
patch an existing diagram based on the users additions or deletions, I've
opted to scrap the existing diagram and reload it. So I create a new diagram
and pass it to setContents. This works just fine, but I was wondering about
the efficiency aspects.
The diagram has a lot of icons, and quite a few nodes and connections - is
there anything I can do so that System resource are reclaimed asap ? Beyond
models and editparts, I was concerned about figures, SWT widgets, etc.
Any suggestions ?
Brian.

There are no OS handles in draw2d. If you are using images heavily, you
should have a central place where images are made available and disposed
when appropriate.
