The assignProperty() function is used for defining property assignments QStyleOption and its subclasses contain all the information that QStyle functions need to draw a graphical element. If the checkbox is checked, the group box’s children are enabled; otherwise, they are disabled and inaccessible. (I had to create a class called Dataframe, to make the example work without pandas. This guide covers everything from basic toggles to advanced customization for a dynamic user experience. The buttons in a button group are usually checkable QPushButton s, QCheckBox es (normally for non-exclusive button groups), or QRadioButton s.
