I haven't compiled and run yet, so I assume it looks awesome.

I looked at the code, though, e.g.,

  http://hg.savannah.gnu.org/hgweb/octave/rev/389b09a914e2

and I would suggest that we try to not introduce callbacks in the way 
you have done.  The problem with the callbacks is it is connecting two 
threads with functions.  We should be using the Qt signal/slot mechanism 
across threads.  Otherwise there is a good chance we're unnecessarily 
restricting capabilities and possibly making programming more difficult 
down the road.

Feel free to continue though.  I have a dialog patch almost ready to go 
that should give an example of what I'm talking about.  I'll write back 
in a couple days and see what we can do to remain within the signal/slot 
concept.
