Tkinter messagebox – Ask Retry or Cancel
In Tkinter, the messagebox.askretrycancel() method is used to ask if the user would like to retry or cancel an operation with two actions: Retry, Cancel.
If user clicks on Retry button, then askretrycancel() returns True, or else if user clicks on Cancel button, then askretrycancel() returns False. Based on the returned value, we can proceed with the required logic using an if else statement.
In this tutorial, you will learn how to ask a question in a message box using messagebox.askretrycancel() method in Tkinter, with an example program.
Syntax of messagebox.askretrycancel()
The syntax of askretrycancel() method is
|title||This string is displayed as title of the messagebox. [How a title is displayed in message box depends on the Operating System. ]|
|message||This string is displayed as a message inside the message box.|
1. Ask if user want to proceed with the operation
For example, consider that you have created a GUI application using Python Tkinter, and you would like to ask the user a question: Do you want to proceed?
You can ask the question with OK or Cancel actions in a messagebox, as shown in the following code.
import tkinter as tk from tkinter import messagebox # Create the main window window = tk.Tk() # Ask for confirmation: OK or Cancel result = messagebox.askretrycancel("Sample Operation Interrupted", "Do you want to retry?") if result: print("User clicked Retry") else: print("User clicked Cancel") # Run the application window.mainloop()
After user takes an action by clicking on either of the buttons, the return value is stored in result variable. Based on this value, we print an output.
If user clicks on Retry button, askretrycancel() returns True, and we get the following output in Terminal.
If user clicks on Cancel button, askretrycancel() returns False, and we get the following output in Terminal.
In this Python Tkinter tutorial, we learned how to ask a question with Retry and Cancel actions in a message box in Tkinter, with examples.
