Add widget QCheckBox to QFileDialog in PyQt5 Python not working

Adding a QCheckBox widget to a QFileDialog in PyQt5 can be a useful feature when you want to provide additional options or filters to users while selecting files. However, there are certain considerations and steps you need to follow to ensure that the implementation works correctly. Below is a step-by-step tutorial with code examples to guide you through the process.
Make sure you have PyQt5 installed in your Python environment. You can install it using the following command:
In your Python script, start by importing the required modules:
Create a custom QDialog class that inherits from QFileDialog. This class will be responsible for including the QCheckBox widget:
In your main script, create an instance of QApplication, then use the custom file dialog:
Save your script and run it. You should see a file dialog with an additional checkbox labeled "Enable Custom Option." The customOptionChanged function is called when the checkbox state changes, allowing you to handle custom logic based on whether the checkbox is checked or unchecked.
With these steps, you should be able to add a QCheckBox widget to a QFileDialog in PyQt5 and handle its state changes effectively.
