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

#TBOT Show 7: The Significance of Dorsey’s Bitchat, Worlds First eSIM Hack, Mexico’s Digital ID, New Show Source Insights Took a week off and now I’m back. 😎 (with a new addition to the show?!) (also - big sorry for the show being 40 minutes) WATCH THE SHOW ON SUBSTACK https://odysee.com/@takebackourtech:f/tbot-show-7:6 Here’s the stories for the week: Jack #Dorsey’s #Bitchat - The Real Story: The tech mogul Jack Dorsey released a censorship proof messaging app in late June - named Bitchat. It runs a #bluetooth#mesh network, end to end #e2e#encryption, and rolling IDs and is picking up traction. I share my thoughts on the app, and concerns I have - but that’s not even the real story. I think Jack has a bigger message than just the app. World’s First #eSIM Hack: A security lab out of Poland just demonstrated a hack on one of the largest SIM providers for IoT devices. We’ll get techy in our understanding and ask the question, could this impact our phones? #DigitalID, Coming Soon To #Mexico: The Mexican government has signed a new #Biometric#ID law, known as the CURP. How is this enforced and what does it mean for Mexican residents? Find out today. Decentralized #Video Conferencing: Recently I’ve been relying more on video conferences instead of calling people, especially while traveling. Good thing I’ve got the #Jitsi app, I’ll show you my setup! #videocall New Show, “Source Insights”: You follow #TBOT to stay informed on tech freedom.
