Changing the background color of a Tkinter window is a common task for creating visually appealing GUI applications in Python. In this article, we will explore three different approaches to achieve this.

Change a Tkinter Window Background Color

Below are some of the ways by which we can change a Tkinter window background color using Python:

Using the configure Method

The configure method allows you to change various properties of the Tkinter window, including the background color. Here’s how you can do it:

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Tkinter Window Background Color")

# Set the window size
root.geometry("400x300")

# Change the background color using configure
root.configure(bg='lightblue')

# Run the application
root.mainloop()

Output:

Using the Frame Widget

Another way to change the background color is by placing a Frame widget that covers the entire window and setting its background color. This method allows for more flexibility, such as adding other widgets on top of the frame.

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Tkinter Window Background Color")

# Set the window size
root.geometry("400x300")

# Create a frame and place it in the window
frame = tk.Frame(root, bg='lightgreen')
frame.place(relwidth=1, relheight=1)

# Run the application
root.mainloop()

Output:

Using the Canvas Widget

A Canvas widget can also be used to change the background color. The Canvas widget is particularly useful if you want to draw shapes or add more complex graphical elements.

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Tkinter Window Background Color")

# Set the window size
root.geometry("400x300")

# Create a canvas and set its background color
canvas = tk.Canvas(root, bg='lightcoral')
canvas.pack(fill=tk.BOTH, expand=True)

# Run the application
root.mainloop()

Output:
