Write a Python GUI program to create a Checkbutton widget using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
my_boolean_var = tk.BooleanVar()

my_checkbutton = ttk.Checkbutton(
    text="Check when the option True",
    variable=my_boolean_var
)
my_checkbutton.pack()
root.mainloop()

Explanation:

In the exercise above -

• import tkinter as tk - Import the Tkinter library (tkinter).
• from tkinter import ttk - Import the themed Tkinter library (ttk).
• root = tk.Tk() - Create the main Tkinter window (root).
• my_boolean_var = tk.BooleanVar() - Create a BooleanVar (my_boolean_var) to hold a boolean variable.
• my_checkbutton = ttk.Checkbutton(text="Check when the option True", variable=my_boolean_var) - Create a Checkbutton widget (my_checkbutton) using ttk.Checkbutton. Set the text for the Checkbutton. Associate the BooleanVar (my_boolean_var) with the Checkbutton.
• my_checkbutton.pack() - Display the Checkbutton within the main window.
• root.mainloop() - Start the Tkinter main loop to run the GUI application.
