Tkinter menu does not appear

I'm learning Tkinter using a tutorial and the menu isn't appearing. I've found a few other examples of this happening, but they all appear to be Mac or simple typos. Here's my minimum example:

from tkinter import *

# Create the root window
root = Tk()
root.title("DebugExample")

# Menu bar
menu_bar = Menu(root)
item = Menu(menu_bar)
item.add_command(label='New')
item.add_cascade(label='File', menu=item)
root.config(menu=menu_bar)

# Task name label
lTaskName = Label(root, text = "Just some text to give content for the window")
lTaskName.grid()

# Run the main loop
root.mainloop()

And the result: Generated Window

I can see that there's an extra line below the title that's not there if I take out the menu code altogether so I thought perhaps it was a spacing thing, but I can't drag the line lower or otherwise expand it. I'm running Python 3.6.8 on RHEL 8.9 if that's helpful. Thank you!

Solution

  • The following line

    item.add_cascade(label='File', menu=item)

    should be changed to

    menu_bar.add_cascade(label='File', menu=item)
