Is There Any Differences Between Python2 And Python3 About Adding Menu Bar To Frame In Tkinter?

I'm trying to porting a project 2to3 on python, and stuck in tkinter. In python2, there is no problem with adding menu bar to Frame in tkinter, but python3 occured attribute error.

Solution 1:

You should not be using tk_menuBar in either python 2 or 3. The docstring for that function says this:

"""Do not use. Needed in Tk 3.6 and earlier."""

Note: tk 3.6 went obsolete back in the early 90's.

There is no way to attach a menu to a Frame widget. You can add instances of Menubutton to simulate a menubar, but you won't get a real menubar.

You can attach a Menu to the root window or to instances of Toplevel by configuring the menu attribute.

import tkinter as tk

root = tk.Tk()

menubar = tk.Menu()
fileMenu = tk.Menu()
editMenu = tk.Menu()
viewMenu = tk.Menu()

menubar.add_cascade(label="File", menu=fileMenu)
menubar.add_cascade(label="Edit", menu=editMenu)
menubar.add_cascade(label="View", menu=viewMenu)

root.configure(menu=menubar)

root.mainloop()
