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

🚀 TON's Catchain 2.0 Upgrade Enhances Speed and Validator Rewards TON has announced the implementation of its Catchain 2.0 consensus upgrade, which significantly improves transaction speed and validator incentives. According to NS3.AI, the upgrade reduces block times to 400 milliseconds and accelerates payment settlement to approximately one second. Additionally, the change is expected to increase annual inflation to 3.6%, up from around 0.6%, as the faster block production boosts rewards for validators. #TON#Catchain2.0 #Blockchain#ConsensusUpgrade#TransactionSpeed#ValidatorRewards#Cryptocurrency#CryptoNews#BlockchainTechnology#DeFi
