hi,

I'm replying to this from the archives so the threading might be
messed up.  Somehow I lost your original reply.

I disagree.  The older widgets have certain methods that folks might
use.  I see no harm in having two different implementations of
widgets.  That way if someone would like a customized widget they
could learn how to do it by looking at the older widgets.  Also by
breaking backwards compatibility we make it very hard for people who
use specific features of the old widgets that have no sensible
equivalents in the newer widgets.  I think backwards compatibility is
important and see no reason to break it for the Python widgets.
David, what do you think?

Anyway, I have working widgets (its a first cut and might not be
perfect) for Tkinter, wxPython and pyGTK.  I'll wait for comments on
the bacwards compatibility today and then commit the widgets later
today.

Thanks.  It works now.

Yes, you started it on the vtk-developers list and I sent my reply to
the vtkusers list.
