Python Tkinter menu example - Create menu options

Python Tkinter Events and Event Handling: Exercise-11 with Solution

Write a Python program that uses Tkinter to create a menu with options like "File," "Edit," and "Help." Implement event handling for the menu items to perform actions.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import Menu

def open_file():
    print("File > Open command clicked")

def save_file():
    print("File > Save command clicked")

def cut_text():
    print("Edit > Cut command clicked")

def copy_text():
    print("Edit > Copy command clicked")

def paste_text():
    print("Edit > Paste command clicked")

def about():
    print("Help > About command clicked")

root = tk.Tk()
root.title("Menu Example")

menu_bar = Menu(root)
root.config(menu=menu_bar)

# File menu
file_menu = Menu(menu_bar, tearoff=0)
menu_bar.add_cascade(label="File", menu=file_menu)
file_menu.add_command(label="Open", command=open_file)
file_menu.add_command(label="Save", command=save_file)
file_menu.add_separator()
file_menu.add_command(label="Exit", command=root.destroy)

# Edit menu
edit_menu = Menu(menu_bar, tearoff=0)
menu_bar.add_cascade(label="Edit", menu=edit_menu)
edit_menu.add_command(label="Cut", command=cut_text)
edit_menu.add_command(label="Copy", command=copy_text)
edit_menu.add_command(label="Paste", command=paste_text)

# Help menu
help_menu = Menu(menu_bar, tearoff=0)
menu_bar.add_cascade(label="Help", menu=help_menu)
help_menu.add_command(label="About", command=about)

root.mainloop()

Explanation:

In the exercise above -

• Import the "tkinter" library.
• Create a simple 'Tkinter' window titled "Menu Example."
• Create a Menu object menu_bar to hold our menu options.
• Create three menu options: "File," "Edit," and "Help" using the Menu objects file_menu, edit_menu, and help_menu.
• For each menu, we add commands or menu items using the add_command method. Whenever the menu item is clicked, a label and a callback function are specified.
• Add the "File," "Edit," and "Help" menus to the menu_bar using the add_cascade method.
• When you run the program, you'll see a window with the "File," "Edit," and "Help" menus. When you click on the menu items, the corresponding actions are triggered, and the messages are printed to the console.
• Finally, start the Tkinter main loop with "root.mainloop()".

Output:

File > Open command clicked
File > Save command clicked
Edit > Cut command clicked
Edit > Copy command clicked
Edit > Paste command clicked
Help > About command clicked
