В фреймворке PyQt (и PySide тоже) часто встречается настройка чего-либо с помощью так называемых флагов. widget.setWindowFlags(Qt.Window) Взаимодействие нескольких флагов делается с помощью бинарных (или побитовых) операторов. Несколько флагов можно указать с помощью оператора "|" list_item.setFlags(Qt.ItemIsSelectable | Qt.ItemIsEnabled) исключить флаг из уже имеющегося набора можно так list_item.setFlags(list_item.flags() ^ Qt.ItemIsEnabled) Добавить новый флаг к имеющимся можно так list_item.setFlags(list_item.flags() | Qt.ItemIsEnabled) А проверка наличия делается так is_enabled = item.flags() & Qt.ItemIsEnabled > 0 Почему именно так? Всё дело в том как именно работают побитовые операторы. Но об этом в следующем посте. #qt

Only sit on seats without markings when dining in at #OurHawkerCentres to maintain #SafeDistancing. If the seating capacity is limited, #BringYourOwn clean containers and choose to take-out instead. Let’s unite to #FightCOVID19 together! 💪#SGUnited
