“How Do I Handle The Window Close Event In Tkinter?” ~ bbaz
Tkinter is a commonly used GUI (Graphical User Interface) library for Python. One common issue faced while working with Tkinter is managing the window close event. This blog will provide a quick guide on how to manage and handle the close event properly.
The Problem with Closing a Window
Closing a window using the ‘X’ button on the top right corner of the window can cause issues if it is not handled properly. If the application is not closed properly, there could be memory leaks or other similar issues.
Methods of Closing a Window in Tkinter
In Tkinter, there are generally two methods of closing a window: using a button and using the ‘X’ button. It is important to handle both events correctly to prevent any issues.
Closing a Window Using a Button
Closing a window using a button is relatively simple. In Tkinter, we can create a button and assign a function that closes the window to it. The following code shows an example of how to do this:
def myFunction(): root.destroy()
Closing a Window Using the ‘X’ Button
Closing a window using the ‘X’ button is a bit more complicated. By default, clicking the ‘X’ button only hides the window instead of destroying it. To properly handle this event, we need to override it using a protocol. The following code shows how to do this:
root.protocol(WM_DELETE_WINDOW, myFunction)def myFunction(): root.destroy()
|Using a Button||Simple and easy to implement||User may not know to use the button to close the window|
|Using the ‘X’ Button||Allows for standard window closing behavior||Requires more complex implementation|
Overall, it is important to handle the window close event properly to prevent any potential issues. If the application is simple and does not require complex closing behavior, using a button may be the best solution. However, if the application requires standard closing behavior using the ‘X’ button, implementing the protocol method is necessary.
Thank you for taking the time to read through this guide on managing the
Tkinter window close event. We hope that this guide has been helpful in understanding how to properly manage the closing of windows in
As you have learned, the window close event is an important aspect of any
Tkinter application, as it allows you to properly exit your application and perform necessary clean-up tasks. By properly handling this event, you can create a more user-friendly application that gives your users a better experience.
We encourage you to take what you have learned here and apply it to your own
Tkinter projects. By doing so, you will be able to create more robust and reliable applications that provide a better overall experience for your users.

The window close event in Tkinter refers to the action of closing the window or application that has been created using the Tkinter GUI library in Python.
You can manage the window close event in Tkinter by binding a function to the ‘WM_DELETE_WINDOW’ protocol. This function will be called whenever the user attempts to close the window or application.
The purpose of managing the window close event in Tkinter is to provide a way for the user to gracefully exit the application and perform any necessary cleanup tasks before the program terminates completely.
Yes, you can prevent the window from being closed in Tkinter by overriding the default ‘WM_DELETE_WINDOW’ protocol function with your own custom function that performs some action before allowing the window to be closed. You can then use the ‘protocol’ method to set the new function as the handler for the ‘WM_DELETE_WINDOW’ event.
If you don’t manage the window close event in Tkinter, the default behavior of the operating system will be used to close the window or application. This may not always be desirable, as it can result in unexpected behavior or incomplete cleanup tasks.
