[pygtk] Glade 3 MenuItem and Submenu

[svabodafree at libero.it]

Where I can find some documentation more detailed on the utilization of Glade 
and  Python?  I am a novice of python and if I did not understood badly the 
usage of  Glade  is complementary with the Gtk of Python.  Now I am 
experiencing to do the mine 1° program with these two tools, but am in 
difficulty.  I created some Menuitem in Glade, and then I would like to create 
from program (therefore to be able to use more times the same window) the 
Submenu to one or more of these menuitem and then obviously I would like to be 
able manage them.  Someone could help me or to give indications to be able move 
me the solution of my problem?  

Thanks Giovanni
