No, I don't build the entire interface at one point. In the first
section, I build an interface that uses the first toplevel. Later, I
may (or may not) build an interface that uses the second top level.
Unfortunately, I cannot use the gtk_builder_add_objects_from_file()
method since I need to be compatible with version 2.12. IIRC that
method was added later on.
Note that I am converting this work from a libglade interface to a
gtk.builder interface. libglade seems to handle the
multiple-top-levels-in-one-glade-file thing a little easier, though
that could just be my lack of understanding,
