Hmmm. No idea what's wrong here, but it could just be a GTK+ issue (and
the right-most column is notoriously confusing when resizing autowidth
lists, which further complicates things). I'd suggest just capturing
sizes "periodically" or on application exit (god forbid crashes)

Well, I'd suggest you just do it explicitly in your application exit
handler (after mainquit is called, for instance).
In my experiments, it seems that a lone CList does get at least
unrealize when it's window is closed (unmap and unmap_event didn't fire):
>>> def foo(*a):
... print "Unrealized", a
>>> w = gtk.GtkWindow()
>>> c = gtk.GtkCList()
>>> w.add(c)
>>> w.show_all()
>>> c.connect("unrealize", foo)
10
At this point I close the window, and:
>>> Unrealized (<gtk.GtkCList instance at 0x402c55ac>,)
It could be that the ScrolledWindow around the CList makes a difference,
though I find that unlikely.
Note that unrealize needs the mainloop to be triggered -- if the
mainloop is already gone, no event will be triggered. I'd suggest not
relying on signals and just doing it explicitly on your application
shutdown facility (you do have an application shutdown facility, right?
<wink>)
Take care,
