Certainly! In this tutorial, we will explore how to create a Tkinter GUI application in Python 3 and ensure that all child windows are destroyed when the main/root window is closed. We'll be using the Tk class for the main window and the Toplevel class for child windows.
Let's get started:
Import Tkinter Module:
First, import the tkinter module.
Create the Main Window:
Create the main/root window using the Tk class.
Define Child Window Function:
Define a function to create a child window when called.
Create a Button to Open Child Window:
Create a button in the main window that, when clicked, will call the function to create a child window.
Destroy All Child Windows at Exit:
To ensure that all child windows are destroyed when the main window is closed, override the default behavior of the close button and add a function to destroy all child windows.
In this example, on_closing is a function that iterates through all the child windows of the main window and destroys them. It is then called when the user attempts to close the main window.
Run the Tkinter Main Loop:
Start the Tkinter main loop to display the GUI.
Here's the complete code:
This example provides a simple structure for a Tkinter application with a main window and the ability to create child windows. The on_closing function ensures that all child windows are destroyed when the main window is closed. Feel free to modify and expand upon this example based on your specific requirements.
