[Tutor] Menus / Mac

[Joel Levine]

I'm trying to learn menus, starting with a textbook example.

The textbook example (pasted below) doesn't work, but doesn't die either:  It opens a window that has no menu.

I'm guessing it is a Mac problem.  I've tried it on 3 different Macs, with slightly different dates and configurations of Python and its libraries.  Same story each time.

But, mailing the same program to someone who pasted it into a PC program -- it was fine.  

On the Mac, I'm running straight from Terminal/Unix, that is, I'm not using IDLE.

Hard to believe that something this basic would not be running & not be noticed -- but I'm at a loss.

The program is below.

Thanks,
Joel Levine


from Tkinter import *

def callback():
    print "called the callback!"
    
root = Tk()
# create a menu
menu = Menu(root)
root.config(menu=menu)

filemenu = Menu(menu)
menu.add_cascade(label="File", menu=filemenu)
filemenu.add_command(label="New", command=callback)
filemenu.add_command(label="Open...", command=callback)
filemenu.add_separator()
filemenu.add_command(label="Exit", command=callback)
helpmenu = Menu(menu)
menu.add_cascade(label="Help", menu=helpmenu)
helpmenu.add_command(label="About...", command=callback)
mainloop()
