First: I apologize if this is more of a GTK problem than a PyGtk
problem. I haven't used GTK other than by Python, so it seems
best to start here.
I've bumped up against problems using GtkNotebook, for which I'd
appreciate any help I can get.
I would like to update the contents of a page of a notebook just
before it is displayed. 'page_callback' does just that in a trivial
manner, at least when it's connected to a button callback as shown
by #X# lines. When I try the code below, page_callback falls into
a recursion hole at the line marked #<<<<<<<<<<<<<<<<.
I see two possible solutions: somehow call off the callback when
the page is removed and inserted, or find an entirely different
way to change the contents of what's being displayed on a page.
The problem is that I've found no examples or descriptions of how
either of these might be accomplished.
(I've considered mucking around inside a frame inside the page,
but don't see a clean way to get a handle on the right frame
(or is this what .get_data and .set_data are all about?))
Can anyone give me a hand?
