You'll probably do better if you email the wxPython user's group for
these kinds of things. But I'll take a shot at it anyway.

Looking at the GridBagSizer's docs, I found it has the following
method: CheckForIntersection. You could use that to make sure there
are no intersections and then handle it when they occur.

See the docs for more info:

The mailing list is here:

Without knowing what your layout scheme is or how you add the widgets
to the sizer, it's difficult to give a more specific answer. Since you
say it's a dialog, you might want to consider using a simpler sizer or
a group of simpler sizers nested in one another. There's an entry on
the wiki that might be helpful to you as well.

Hope that helps.
