Tkinter askretrycancel

Summary: in this tutorial, you’ll learn how to use the Tkinter askretrycancel() function to show a Retry/Cancel confirmation dialog.

Introduction to the Tkinter askretrycancel() function

Sometimes, the application performs a task but fails to do so because of an error.

For example, you may want to connect to a database server. However, the database server is currently not reachable. It may be offline for a short period of time.

In this case, you can display a confirmation dialog that allow users to reconnect to the database or just keep the application as is.

To display the Retry/Cancel dialog, you can use the askretrycancel() function:

answer = askretrycancel(title, message, **options)

Code language: Python (python)

The askretrycancel() function returns True if the Retry button is clicked. If the Cancel button is clicked, it returns False.

Tkinter askretrycancel() function example

The following program shows a button that simulates a bad database connection:

If you click the button, it’ll show a Retry/Cancel dialog saying that the database server is not reachable. It’ll also request you to reconnect to the database server:

If you click the Retry button, it’ll show a dialog indicating that the program is attempting to reconnect to the database server.

Program:

import tkinter as tk from tkinter import ttk from tkinter.messagebox import askretrycancel, showinfo # create the root window root = tk.Tk() root.title('Tkinter OK/Retry Dialog') root.geometry('300x150') # click event handler def confirm(): answer = askretrycancel( title='Connection Issue', message='The database server is unreachable. Do you want to retry?' ) if answer: showinfo( title='Information', message='Attempt to connect to the database again.') ttk.Button( root, text='Connect to the Database Server', command=confirm).pack(expand=True) # start the app root.mainloop()

Code language: Python (python)

Summary

• Use the askretrycancel() function to display a Retry/Cancel dialog to confirm users to carry an operation again.
