Hi all,
I thought it'd be easier to illustrate the problem I'm trying to solve by
posting a video showing my view in action.
http://www.babbleonchat.com/HelpGEF.html
A few points:
-This is a view, not an editor.
-Before I introduced the AP/MP groups (you'll see what I mean by that in
the video), the ShortestPathConnectionRouter was working perfectly,
avoiding all obstacles between its endpoints.
-After adding these groups, connections only avoid obstacles sitting at
the 2nd level, meaning one level above root. By levels, I'm talking about
parent-child hierarchy depth.
A few sub-questions:
-Because it's a view, I can't easily provide an outline page for it. Is
there a way to do this? (Showing a scaled-down representation in the
outline view and superimposing the viewport's current bounds, etc)
-How do I implement animated zooming?
Any help would be greatly appreciated, even if it's just pointing me to
related documentation.
Cheers,
-Dan.

The current router is a mapping from figures to obstacles, and then solving
a path and setting the connections points. You could write your own router
that performs a deeper collection of obstacles, and then does the same
thing. There are issues around performance and updating that make the ideal
solution challenging.
