You could do this, or you could pass the XML object around, or you could get
the widgets you need in one place and pass them to where they are needed.
xml = gtk.glade.XML(GLADEFILE)
foo_widget = xml.get_widget('foo')
baz_object = Baz(foo_widget)
xml.signal_autoconnect(baz_object)

Just use get_widget to get these widgets from the tree by name. Gtk is not
a framework like Qt; you don't sublcass any framework classes.

There is just one namespace, so you do have to be careful to use unique
names for things you want to be unique.

If you give then the same name, 'delete', the handlers are the same. The
names aren't qualified in the glade file.
You *can* use the same name for the handler. Howerver, whatever callback
you connect to the handler will get called when either signal is emitted.
If that's not what you intend, give the handlers unique names (if you give
your widgets unique names, this is the default behavior.)

Ditto. But, again, by default these will be given different handler names:
'on_app1_delete_event' and 'on_window1_delete_event'.

I think you mean objects rather than classes, right? (Unless you do want
different behavior for each notebook).
You can't inherit from already existing widget objects, but you can use
aggretation or delegation:
class NotebookController(object):
def __init__(self, notebook):
self.notebook = notebook
...
def foo(self, bar):
self.notebook.foo(bar)
notebook1 = NotebookController(xml.get_widget('notebook1'))
> Can I use handlers defined in glade in my custom classes ?
Sure, see the FAQ entry above for one way to do it.
