Mastering Popup Dialog Boxes in Tkinter: Learn How to Create and Use Them

Popup dialogue boxes are essential in modern programming. They appear on the screen to detect or inform the user about any action or warning.

Tkinter provides a variety of popup dialogue boxes such as message boxes, error message boxes, warning messages, and question message boxes. These dialogues help users to recognize errors, take necessary actions, and make decisions about the program.

In this article, we will explore the different types of popup dialogues boxes and how to create them in Tkinter.

Explanation of Popup Dialogue Boxes

Popup dialogue boxes are small windows that pop up on the screen to provide information or seek input from the user. They are important elements in most applications or systems that require user interaction.

Popup dialogue boxes give different types of messages such as informative, warning, or error messages. They also provide options to the user such as yes/no or ok/cancel.

In python, tkinter module provides the messagebox class to create different types of dialogues boxes.

Using messagebox class from the tkinter module

The messagebox class is a part of the tkinter module, designed to provide popup dialog boxes. The module has several methods, each containing a specific type of popup box.

The following are the essential types that we can create using the messagebox class.

Creating Different Types of Dialog Boxes with Messagebox in Tkinter

showinfo() method for displaying information

The showinfo() method displays an informational message box. This box contains an icon that specifies an information symbol and a message to the user.

When we use this method, a small window appears on the screen with an ‘OK’ button. An example of this method creating an information message box is:

messagebox.showinfo(“Information”, “Welcome to our program”)

showerror() method for displaying error messages

The showerror() method displays an error message box. This box contains an icon that specifies an error symbol and a message to the user.

When we use this method, a small window appears on the screen with an ‘OK’ button. An example of this method creating an error message box is:

messagebox.showerror(“Error”, “There was an error while processing the request”)

showwarning() method for displaying warning messages

The showwarning() method displays a warning message box. This box contains an icon that specifies an alert symbol and a message to the user.

When we use this method, a small window appears on the screen with an ‘OK’ button. An example of this method creating a warning message box is:

messagebox.showwarning(“Warning”, “The program is about to close.

Do you want to save changes?”)

askyesno() method for displaying yes/no buttons

The askyesno() method displays a message box that asks the user for a ‘yes’ or ‘no’ answer. This box contains an icon that specifies a question symbol, a message to the user, and two button options (‘Yes’ and ‘No’).

When we use this method, a small window appears on the screen with ‘Yes’ and ‘No’ buttons. An example of this method creating a ‘yes/no’ message box is:

messagebox.askyesno(“Delete”, “Are you sure you want to delete the selected item?”)

askokcancel() method for making ok/cancel decisions

The askokcancel() method displays a message box that asks the user to make an ‘OK’ or ‘Cancel’ decision.

This box contains an icon that specifies a question symbol, a message to the user, and two button options (‘OK’ and ‘Cancel’). When we use this method, a small window appears on the screen with ‘OK’ and ‘Cancel’ buttons.

An example of this method creating an ‘OK/Cancel’ message box is:

messagebox.askokcancel(“Exit”, “Do you want to exit the program?”)

askretrycancel() method for retrying procedures

The askretrycancel() method displays a message box that asks the user to ‘Retry’ or ‘Cancel.’ This box contains an icon that specifies a question symbol, a message to the user, and two button options (‘Retry’ and ‘Cancel’). When we use this method, a small window appears on the screen with ‘Retry’ and ‘Cancel’ buttons.

An example of this method creating a ‘Retry/Cancel’ message box is:

messagebox.askretrycancel(“Error”, “There was an error while processing this request. Do you want to retry?”)

Conclusion

Tkinter provides a messagebox class to create popup dialogues boxes. By using the messagebox class, we can create different types of message boxes such as information, error, warning messages, and question message boxes.

We can also provide option buttons to the user such as ‘yes/no’, ‘OK/Cancel’, and ‘Retry/Cancel’ in the message box. The message box is an essential element of any program/application that requires user interactions.

In the previous section, we discussed the different types of popup dialogue boxes we can create using the messagebox class in Tkinter. In this section, we will look at examples of each method and the output we get when we run the code.

showinfo() example code and output

The showinfo() method creates an informational message box and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

messagebox.showinfo(“Information”, “Welcome to our program!”)

“`

Output:

![showinfo output](https://raw.githubusercontent.com/AI-Patashala/tkinter-popup-dialogue-boxes-tutorial/main/showinfo-output.png)

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method. We then use the showinfo() method to create an informational message box with a title “Information” and a message “Welcome to our program.” The output of our code is shown in the picture above.

showerror() example code and output

The showerror() method creates an error message box and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

messagebox.showerror(“Error”, “There was an error while processing your request!”)

“`

Output:

![showerror output](https://raw.githubusercontent.com/AI-Patashala/tkinter-popup-dialogue-boxes-tutorial/main/showerror-output.png)

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method. We then use the showerror() method to create an error message box with a title “Error” and a message “There was an error while processing your request.” The output of our code is shown in the picture above.

showwarning() example code and output

The showwarning() method creates a warning message box and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

messagebox.showwarning(“Warning”, “The data entered is invalid. Please check and try again.”)

“`

Output:

![showwarning output](https://raw.githubusercontent.com/AI-Patashala/tkinter-popup-dialogue-boxes-tutorial/main/showwarning-output.png)

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method.

We then use the showwarning() method to create a warning message box with a title “Warning” and a message “The data entered is invalid. Please check and try again.” The output of our code is shown in the picture above.

askyesno() example code and output

The askyesno() method creates a message box with ‘Yes’ and ‘No’ buttons and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

response = messagebox.askyesno(“Confirmation”, “Do you want to delete the selected file?”)

if response == 1:

print(“

File deleted”)

else:

print(“

Deletion cancelled”)

“`

Output (when ‘Yes’ button is clicked):

“`

File deleted

“`

Output (when ‘No’ button is clicked):

“`

Deletion cancelled

“`

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method. We then use the askyesno() method to create a message box with a title “Confirmation” and a message “Do you want to delete the selected file?” The output of the user’s response is determined using if-else statements, based on which button was clicked.

If the ‘Yes’ button is clicked, the message “

File deleted” is printed. If the ‘No’ button is clicked, the message “

Deletion cancelled” is printed.

askokcancel() example code and output

The askokcancel() method creates a message box with ‘OK’ and ‘Cancel’ buttons and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

response = messagebox.askokcancel(“Exit”, “Do you want to exit the program?”)

if response == 1:

print(“

Program has been exited”)

else:

print(“

Program exit cancelled”)

“`

Output (when ‘OK’ button is clicked):

“`

Program has been exited

“`

Output (when ‘Cancel’ button is clicked):

“`

Program exit cancelled

“`

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method. We then use the askokcancel() method to create a message box with a title “Exit” and a message “Do you want to exit the program?” The output of the user’s response is determined using if-else statements, based on which button was clicked.

If the ‘OK’ button is clicked, the message “

Program has been exited” is printed. If the ‘Cancel’ button is clicked, the message “

Program exit cancelled” is printed.

askretrycancel() example code and output

The askretrycancel() method creates a message box with ‘Retry’ and ‘Cancel’ buttons and shows it on the screen. Let’s take a look at an example:

“`

import tkinter as tk

from tkinter import messagebox

root = tk.Tk()

root.withdraw()

response = messagebox.askretrycancel(“Error”, “There was an error while processing your request. Do you want to retry?”)

if response == 1:

print(“

Procedure was retried”)

else:

print(“

Retrying procedure was cancelled”)

“`

Output (when ‘Retry’ button is clicked):

“`

Procedure was retried

“`

Output (when ‘Cancel’ button is clicked):

“`

Retrying procedure was cancelled

“`

In this example, we import the necessary libraries, create a Tkinter object, and hide it using the withdraw() method. We then use the askretrycancel() method to create a message box with a title “Retry” and a message “There was an error while processing your request.

Do you want to retry?” The output of the user’s response is determined using if-else statements, based on which button was clicked. If the ‘Retry’ button is clicked, the message “

Procedure was retried” is printed.

If the ‘Cancel’ button is clicked, the message “

Retrying procedure was cancelled” is printed. In conclusion, popup dialogue boxes are an essential aspect of modern programming.

In Python, the Tkinter module provides the messagebox class to create different types of popup boxes. We covered six types of the messagebox class, including showinfo(), showerror(), showwarning(), askyesno(), askokcancel(), and askretrycancel().

Each method had a different purpose, such as displaying informational messages, warning messages, error messages, or asking the user to make a decision. The examples showcased how each method works, giving us a clear understanding of their functionality.

By using popup dialogue boxes, we can improve the user experience and enhance the functionality of our programs. We can now apply the concepts learned in this article while creating GUIs and enhancing user interactions.
