MessageBox - Tkinter Dialog and MessageBox

The MessageBox is a dialog box in the Tkinter GUI toolkit that is used to display message alerts and prompt for user input. It provides a convenient way for developers to interact with users and display messages in any Python applications that use the Tkinter module.

Syntax

The basic syntax to display a MessageBox in Tkinter is as follows:

import tkinter as tk
from tkinter import messagebox

# Display a messagebox
messagebox.showinfo("<title>", "<message>")

The showinfo method displays a message box with a specified title and message. There are other methods in the messagebox module that can be used to prompt for user input or display warning messages.

Example

Consider the following example, where a MessageBox is displayed when a button is clicked. This example displays the message "Hello Tkinter!" in a message box when the button is clicked.

import tkinter as tk
from tkinter import messagebox

root = tk.Tk()

def display_message():
    messagebox.showinfo("Hello", "Hello Tkinter!")

button = tk.Button(root, text="Click Me", command=display_message)
button.pack()

root.mainloop()

In this example, we define a function display_message that displays a message box using the showinfo method of the messagebox module. A button is created to call this function when clicked.

Output

When the above program is executed, it displays a Tkinter window with a button. When the button is clicked, it displays the message "Hello Tkinter!" in a message box.
