A checkbox can be created using the QCheckBox widget. When creating an new checkbox with the QCheckBox class, the first parameter is the label.
To apply actions to the toggle switch, we call .stateChanged.connect() followed by a callback method. When this method is called, it sends a boolean as state parameter. If checked, its the value QtCore.Qt.checked.
