Closing a Tkinter Window with the OK Button

When creating graphical user interfaces (GUIs) in Python using Tkinter, you may encounter situations where you need to close a window after performing a certain action, such as pressing a button. One common scenario is a dropdown menu where users select an option and then press an "OK" button to confirm their choice. If you've ever wondered how to close the Tkinter window after clicking this button, you're in the right place!

The Problem: Keeping Your Interface Clean

In your Tkinter application, after selecting an option from a dropdown, it's intuitive for the user to want to close the window programmatically. Without this functionality, the window remains open, which could lead to confusion.

Let’s break down a simple example to show how you can implement this behavior effectively.

The Basic Tkinter Setup

Suppose you have the following code snippet that creates a dropdown menu implementing Tkinter:

In the above setup, the OK button prints the selected physician's name but does nothing to close the application window once the user presses the button.

The Solution: Destroying the Window

To properly close the Tkinter window after pressing the "OK" button, you’ll utilize the destroy() method. This method closes the window and ends the Tkinter application. Here's how you can modify the ok function:

Updated Code

Explanation of Changes

Importing Necessary Libraries: The import statement remains the same, ensuring all required Tkinter functionality is available.

The ok() Function:

You still retrieve the selected value and print it for confirmation.

Add the line master.destroy() immediately after print(physician_name). This will close the window as soon as the user clicks OK.

Running the Application: The main application loop (mainloop()) remains unchanged and is essential for keeping the window responsive until closed.

Conclusion

By implementing the master.destroy() method in your Tkinter application, you can create a more user-friendly experience that automatically closes the dropdown window after the user confirms their selection. This simple adjustment not only tidies up your interface but also enhances functionality. Now you're ready to create interactive Tkinter applications that leave a positive impression on your users!
