i want to handle the menu click event but, this missing handler warning is occuring, where i am wrong? im connecting the signal ab with handler abcd on menuitem6, on activate event, is it correct for handling a click event?
here is the error:

abc.py:15: RuntimeWarning: missing handler 'a
bc'
builder.connect_signals({ "on_window_destroy" : gtk.main_quit })
None

here's the code :

abc.py:

        s = model.get_string_from_iter(iter)

        obj = mymodel.get_value(niter, 0)
        cell.set_property('text', obj)

You can use builder.connect_signals(self). Then you just have to make methods that are named like the handler in your xml file. So in this case:

class TutorialApp(object):
    def __init__(self):
        builder = gtk.Builder()
        builder.add_from_file('./tutorial.xml')
        builder.connect_signals(self)
        self.window = builder.get_object('disasm')
        ##rest of you __init__

    def abc(self, menuitem):
        print "tst"

    def on_window_destroy(self, window):
        gtk.main_quit()
