Hi:

You can create a class (and instantiate an object) with the methods, and
pass "self" to connect_signals. Something like:

class myclass:

    def __init__(self):
        builder = Gtk.Builder()
        builder.add_from_file("example.glade")
        builder.connect_signals(self)

    def onDeleteWindow(self, widget):
        blah, blah

    def on_btnFoo_clicked(self,btn):
        blah, blah
