I'm not sure if I understand what your problem is. You want to set the
sensitivity of a menu item based on some criteria? One way you would do
this is something like this (simplified example, you would need some
code to set up the app etc, but you should get the idea):
class App:
def __init__(self):
# set up the application, use whatever code you need
self.setup_ui()
# connect a callback to the File/Open menu item
menuitem = self.itemfactory.get_widget("/File/Open")
menuitem.connect("activate", self.cb_open)
def cb_open(self, widget, data = None):
self.load("myfile")
# set the state of File/Save based on if it can be
# modified or not
menuitem = self.itemfactory,get_widget("/File/Save")
if can_modify_file == True:
menuitem.set_sensitive(gtk.TRUE)
else:
menuitem.set_sensitive(gtk.FALSE)
def run(self):
# run the gtk mainloop
gtk.main()
# run the application
app = App()
app.run()
