glade generates an xml file that is processed by the python script

it is the same ml file & the same python script running on both platforms

the basic structure of my call back for testing is:-

import gtk
class GUI:
	def __init__(self):
		builder=gtk.Builder()
		builder.add_from_file('glade.test') # xml file from glade
		builder.get_object('window1').show()
		builder.connect_signals(self)


	def callback(self,widget,data=None):
		print widget	#gives reference to radio button ok
		print widget.name #widget name on windoze, None on linux
	def main (self):
		gtk.main()

def main():
	gui=GUI()
	gui.main()

if __name__ =='__main__':main()

I can provide more detailed sample code if required (including the xml 
from glade)

typed with the left hand?  Now the layout of the QWERTYUIOP typewriter
keyboard was designed, among other things, to facilitate the even use
of both hands.  It follows, therefore, that writing about databases is
not only unnatural, but a lot harder than it appears.
