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

🌍 Canada’s Manitoulin Island is the largest freshwater island in the world. It’s so big that it contains more than 100 lakes, and some of those lakes have islands of their own. ✨ #islands⚡#freshwater⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 In Canada’s Hudson Bay lowlands, vast freshwater wetlands cover over 300,000 square kilometers. This area stores so much water it helps regulate the region’s climate and slow permafrost thaw. ✨ #wetlands⚡#freshwater⚡#climate⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Just 0.001% of all water on Earth is found in rivers, lakes, and the atmosphere. The vast majority is locked away in ice sheets, glaciers, or underground where we rarely see it. ✨ #hydrology⚡#watercycle⚡#freshwater⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Some freshwater wetlands form floating islands—mats of living plants thick enough to walk on. These islands create unique microhabitats and drift slowly across lakes or shallow wetlands. ✨ #wetlands⚡#freshwater⚡#ecology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

🌍 The world's largest freshwater reserves are hidden underground as groundwater, not in lakes or rivers. These reserves are vital for drinking water and irrigation in many regions. ✨ #groundwater⚡#freshwater⚡#resources⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍
