Toggling Fullscreen Mode in a tkinter Application

When creating a GUI application using tkinter, you might want to allow users to switch between fullscreen and windowed mode effortlessly. In this guide, we'll explore how you can implement a simple solution using buttons that toggle fullscreen attributes for your application window.

The Problem: Creating Fullscreen Toggle Buttons

While building a basic application, you may encounter challenges with allowing the window to switch between fullscreen and windowed mode upon user clicks. The initial implementation might result in unintended behavior, such as going fullscreen instantly but minimizing again shortly after. The goal is to have a single button that can check the window’s current mode and toggle it accordingly.

Proposed Solution: A Unified Function to Control Fullscreen Mode

Instead of creating two separate functions (Fulwin for fullscreen and Nonwin for windowed mode), we can simplify the process by unifying them into one. This function will take care of checking the current fullscreen state and changing it accordingly with one click.

Here’s How You Can Implement It:

Define the Unified Function: Instead of having two functions for changing the fullscreen state, we create a single function that checks the current state and toggles it.

Explanation: This function uses not window.attributes('-fullscreen') to check if the window is currently in fullscreen mode and toggles it to the opposite state.

Removing Redundant Functions: Once you have the unified function, you can remove the separate Fulwin and Nonwin functions. This will clean up your code making it more organized and easier to read.

Setting Up Buttons: To implement the functionality, attach the Ifullscreen() function to the button that the user will click to toggle the display mode. Here's how the button code would look:

Full Implementation Example

Putting it all together, your complete tkinter application with fullscreen toggle function should look like this:

Conclusion

By integrating a unified function to handle the fullscreen state, your application becomes simpler and cleaner, ultimately enhancing the user experience. This approach is not only efficient but also helps keep your codebase manageable and easy to modify in the future. Happy coding!
