Well, one way to work around this is to define the gtk.Window in your
code, and have a dummy window defined in Glade that you destroy at
startup:
class MyWindow(gtk.Window): pass
gladewin = xml.get_widget('fake_toplevel')
win = MyWindow()
child = gladewin.get_children()[0]
child.reparent(win)
However, note that you'll loose keyboard accelerators tied to the fake
toplevel. I've fought (and solved -- in GTK+ 1.2) this issue before; see
http://bugs.async.com.br/show_bug.cgi?id=840 for details.

Why not? Do you mean any Python instance or just gtk instances? :-)
>>> class Foo: pass
...
>>> f = Foo()
>>> class Bar: pass
...
>>> f.__class__
<class __main__.Foo at 0x401c626c>
>>> f.__class__ = Bar
>>> f.__class__
<class __main__.Bar at 0x401c629c>
Take care,
