I found the most reliable way (but a bit hacky) to get combo changes was
to catch "hide" from the popup:

--
  GtkWidget *popwin = GTK_COMBO (combo)->popwin;
  gtk_signal_connect (GTK_OBJECT (popwin), "hide",
                      GTK_SIGNAL_FUNC (my_code),
                      (gpointer) my_data);
--

Now in my_code(), just read the contents of the combo entry. You'll just
get selects from the list, you won't see any keyboard stuff. Catch
"activate" from the entry to see when someone edits and presses return.

HTH, John
