The QCheckBox Widget
Explore the functionality of the QCheckBox widget in PyQt6 to create interactive GUI elements. Learn to detect checkbox states, handle multiple selections, and update interface labels or titles based on user input. This lesson guides you through coding with QCheckBox to build dynamic and user-friendly applications.
We'll cover the following...
The QCheckBox widget is a selectable button with typically two states, on or off. Checkboxes are ideal for displaying GUI elements that may be either enabled or disabled because they often have just two states, such as in a survey.

When the user interacts with a box, we perform a method that shows how to determine the widget's current state. The user is free to check all the checkboxes that pertain to them if they want to.
Note: You can pick more than one checkbox at once since checkboxes are not mutually exclusive. Add the checkboxes to a
QButtonGroup...
