Change Icon For Tkinter Messagebox

Question

Is there a way to change the icon of a tkinter message box? Here is my code:

from tkinter import *
import tkinter.messagebox as messagebox

root = Tk()
mess         


        

Answer 1

Following are two possible solutions for your question:

1. Changing the title bar icon

Yes, we can set a custom icon for the title bar in tkinter.

Code:

import tkinter as tk
window = tk.Tk()

# change title bar icon
window.iconbitmap('book_2.ico')

window.mainloop()

NOTE: Use .ico files with the iconbitmap() function

If you set a custom icon for the root window, then this same icon will be set as the title bar icon for all other child window(s) including the message boxes from messagebox module.

Code:

import tkinter as tk
import tkinter.messagebox as tkmb

window = tk.Tk()

# change title bar icon
window.iconbitmap('book_2.ico')

# same icon is also set for the message box
tkmb.showinfo(title='Info', message='Info message box')

window.mainloop()

2. Changing the icon inside message box

No you can not set a custom icon for displaying inside of a message box.

But you have four preset icon options to choose from, the options are:

• error
• info
• question
• warning

You can use them by specifying one of the above 4 values to the icon option.

import tkinter.messagebox as tkmb

tkmb.showinfo(title='Message Box', message='Error message', icon='error')
tkmb.showinfo(title='Message Box', message='Info message', icon='info')
tkmb.showinfo(title='Message Box', message='Question message', icon='question')
tkmb.showinfo(title='Message Box', message='Warning message', icon='warning')

NOTE: The default icon for a

• showinfo() messagebox is info
• showerror() messagebox is error
• showwarning() messagebox is warning
