Ronn, I'm not sure what you're trying to accomplish, but it looks like
you're getting wrapped around the axle a bit. Did you want your "App"
object to instantiate a new Tkinter window, in addition to the "root"
window? For that, you'd need to do this:
class App(Toplevel):
...
But maybe you don't really want/need to do that. Here's a template for
creating a single Tkinter window, with a menubar that contains a single
menu item, "File". And clicking the "File" item, opens a submenu with a
single command, "Hello".
#--------------------------
from Tkinter import *
def hello():
print "hello!"
class App(Tk):
def __init__(self):
Tk.__init__(self)
# create a Menu object
mbar = Menu(self)
# set this Menu to be the App window's menu bar
self['menu'] = mbar
# create another Menu object
fileMenu = Menu(mbar)
# set this Menu to be a submenu of the menu bar, under the name "File"
mbar.add_cascade(label="File", menu=fileMenu)
# add a command named "Hello" to the submenu, and have it
# invoke the function "hello"
fileMenu.add_command(label="Hello", command=hello)
app = App()
app.mainloop()
#--------------------------
Note that instead of this:
self['menu'] = mbar
... you could use this:
self.config(menu=mbar)
