I'm trying to figure out how to use the QGroupBox widget in place of the QButtonGroup widget as the qt docs (link below) 'strongly advise against using it'.
https://doc.qt.io/archives/qt-4.7/q3buttongroup.html
The QButtonGroup had a handy method called QtGui.QButtonGroup.checkedButton() and I'm looking for a way to find the checked radio button contained in the QGroupBox. What is the new best practice for this?
