Changing the tkinter Window Icon

In this tutorial, we will learn how to change the icon of a tkinter window in Python.

Step 1: Install tkinter
Tkinter is included with Python standard library, so you do not need to install it separately. However, make sure you have Python installed on your system.

Step 2: Create a tkinter window
First, let’s create a basic tkinter window with a title and size.

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title('Change Icon Tutorial')
root.geometry('300x200')

# Add content to the window
label = tk.Label(root, text='Hello, World!')
label.pack()

# Run the main loop
root.mainloop()

Step 3: Add an icon to the window
You can change the default icon of the tkinter window by adding an icon file. You can use .ico, .bmp, or .png images as icons.

# Add an icon to the window
root.iconbitmap('icon.ico')

In this example, replace ‘icon.ico’ with the path to your icon file.

Step 4: Handling errors
If the given icon file does not exist, tkinter will throw an error. You can handle this by using a try-except block.

# Try to set the window icon
try:
    root.iconbitmap('icon.ico')
except tk.TclError:
    print("Icon file not found")

Step 5: Test your code
Run the program and see if the icon is displayed correctly on your tkinter window.

That’s it! You have successfully changed the icon of a tkinter window in Python. Experiment with different icon files to customize your application further.
