Create Menu Bar In Python GUI Application

Intro

In this blog, I am going to create a Menu Bar in a Python GUI application. It will display the file and help menus on the application screen. When a user clicks "Exit item" in file menu, the Python application will close.

Software requirement

Python 3.5 and IDLE (Python 3.5)

Programming code

#Create Menubar in Python GUI Application
import tkinter as tk
from tkinter import ttk
from tkinter import Menu
win = tk.Tk()
win.title("Python GUI App")
#Exit action
def _quit():
win.quit()
win.destroy()
exit()
#Create Menu Bar
menuBar=Menu(win)
win.config(menu=menuBar)
#File Menu
fileMenu= Menu(menuBar, tearoff=0)
fileMenu.add_command(label="New")
fileMenu.add_separator()
fileMenu.add_command(label="Exit", command=_quit)
menuBar.add_cascade(label="File", menu=fileMenu)
#Help Menu
helpMenu= Menu(menuBar, tearoff=0)
helpMenu.add_command(label="About")
menuBar.add_cascade(label="Help", menu=helpMenu)
#Calling Main()
win.mainloop()
