Python Tkinter: Creating a simple information dialog


Write a Python program that displays a simple information dialog using Tkinter.

Sample Solution:

Python Code:

import tkinter as tk
from tkinter import messagebox
def show_info_dialog():
    messagebox.showinfo("Information", "This is a simple information dialog.")
root = tk.Tk()
root.title("Information Dialog Example")
info_button = tk.Button(root, text="Show Info Dialog", command=show_info_dialog)
info_button.pack(padx=20, pady=20)
root.mainloop()

Explanation:

In the exercise above -

  • import tkinter as tk - Import the required library for creating the GUI components
  • from tkinter import messagebox – Import messagebox for displaying the information dialog.
  • def show_info_dialog(): - Define a function "show_info_dialog()" that displays an information dialog using messagebox.showinfo(). It takes two arguments: the dialog title ("Information") and the message to display ("This is a simple information dialog.").
  • Next it create the main window using tk.Tk() and set its title.
  • info_button = tk.Button(root, text="Show Info Dialog", command=show_info_dialog) - Create a button named 'info_button' that, when clicked, calls the “show_info_dialog()” function to display the information dialog.
  • info_button.pack(padx=20, pady=20) - Display the information dialog.
  • root.mainloop() - The main event loop, root.mainloop(), starts the Tkinter application.
