No. not multiple, only single. glade.XML() creates
the widgets immediately. My problem is to instruct
not to create (a particular widget say gtk.Window i.e.
toplevel in glade file) the widget immediately. So
that later I can pass my own widget (here gtk.Window
instance, a base class instance) to some func in
libglade so that it assigns properties acc. to glade
file and return completely designed (with children
added) window.
Again I tried this,
class MyWind(gtk.Window):
def __new__(cls, *args, **k):
xml = glade.XML('file.glade')
w = xml.get_widget('toplevel_wind')
return w
def __init__(self):
pass
But the problem here is self (in __init__) is a base
class instance.
Is there any way to convert an base class instance to
derived class instance???
(Note: one cannot set the __class__ attr of instances)
