How to Create a Message Box with tkinter in Python?

Estimated read time 2 min read

To create a message box with tkinter in Python, you can use the messagebox module. The messagebox module provides several methods for creating message boxes, including showinfo, showwarning, showerror, askquestion, askokcancel, askyesno, and askretrycancel.

Here’s an example of how to create a message box using the showinfo method:

import tkinter as tk
from tkinter import messagebox

# Create a new tkinter window
window = tk.Tk()

# Display a message box
messagebox.showinfo("Message", "Hello, World!")

# Run the tkinter event loop
window.mainloop()

In this example, we first import the tkinter and messagebox modules. We then create a new tkinter window using tk.Tk().

We then use the showinfo method to display a message box with the title “Message” and the message “Hello, World!”. The showinfo method returns None, so we don’t need to assign the result to a variable.

Finally, we run the tkinter event loop using window.mainloop().

You can customize the appearance and behavior of the message box by passing additional arguments to the showinfo method. For example, you can specify the parent window, the message box type, and the icon to display. Here’s an example:

import tkinter as tk
from tkinter import messagebox

# Create a new tkinter window
window = tk.Tk()

# Display a message box with a custom icon
messagebox.showinfo("Message", "Hello, World!", parent=window, icon=messagebox.WARNING)

# Run the tkinter event loop
window.mainloop()

In this example, we specify the parent argument to indicate that the message box should be displayed in the window tkinter window. We also specify the icon argument to display a warning icon in the message box.

Note that some message box types, such as askquestion, return a value indicating which button the user clicked. You can use this value to perform different actions based on the user’s response.
