Last update on April 25 2025 12:57:54 (UTC/GMT +8 hours)

Write a Python GUI program to add a canvas in your application using tkinter module.

Sample Solution:

Python Code:

import tkinter as tk 
parent = tk.Tk() 

canvas_width = 100
canvas_height = 80
w = tk.Canvas(parent, 
           width=canvas_width,
           height=canvas_height)
w.pack()

y = int(canvas_height / 2)
w.create_line(0, y, canvas_width, y, fill="#476042")
parent.mainloop()

Explanation:

In the exercise above -

import tkinter as tk - Import the required libraries.
parent = tk.Tk() - Create the main Tkinter window.
canvas_width = 100 canvas_height = 80 - Define canvas dimensions.
w = tk.Canvas(parent, width=canvas_width, height=canvas_height) - Create a Canvas widget within the main window.
y = int(canvas_height / 2) - Calculate the y-coordinate for the horizontal line.
w.create_line(0, y, canvas_width, y, fill="#476042") - Create a horizontal line on the canvas.
parent.mainloop() - Start the Tkinter main loop.
