Когда разрабатываете свой GUI с помощью PyQt для какого-либо софта бывает необходимо позаимствовать цвета из текущего стиля интерфейса. Например, чтобы правильно раскрасить свои виджеты, подогнав их по цвету. Ведь бывает, что ваш GUI используется в разных софтах. Причём некоторые со светлой темой а другие с тёмной. По умолчанию стили наследуются, но если вы задаёте какую-либо раскраску для части виджета через свой styleSheet, то требуется ссылаться на цвета текущего стиля. Как это сделать? Как получить нужный цвет из палитры имеющегося стиля? Это достаточно просто, нужно использовать класс QPalette и его роли. Например, мне нужно достать цвет текста из одного виджета и применить его в другом как цвет фона (не важно зачем именно так, просто захотелось😊). Получаем палитру виджета и сразу достаём нужный цвет, указав его роль. from PySide2.QtGui import QPalette color = main_window.palette().color(QPalette.Text) теперь можем использовать этот цвет в стилях my_widget.setStyleSheet(f'background-color: {color.name()};') Готово, мы динамически переопределили дефолтный стиль используя текущий стиль окна! На самом деле есть запись покороче, в одну строку и без лишних переменных. Не очень-то по правилам CSS, но Qt это понимает. my_widget.setStyleSheet('background-color: palette(Text);') Этот способ не подходит если вам нужно как-то модифицировать цвет перед применением в своих стилях. В этом случае потребуется первый способ. Зато он прекрасно сработает в файле .qss, то есть не придётся в коде прописывать раскраску отдельных элементов через ссылки на палитру, всё красиво сохранится в отдельном файле .qss! QListView#my_widget::item:selected { background: palette(Midlight); } Про имеющиеся роли можно почитать здесь🌍 #qt#tricks

Did Durov Take a Tumble In a Tug of War With Spain? Spain has accused Pavel Durov of “spreading lies” and seeking to undermine democratic institutions after the Telegram founder used the messaging app to attack government plans to introduce a social media ban for under-16s and to hold tech companies responsible for hateful and harmful content. Durov’s extraordinary public intervention – which came a day after Musk called Spain’s prime minister, Pedro Sánchez, a “true fascist totalitarian” over the proposed measures – reveals the rapidly escalating tensions between European governments and powerful global technology chiefs. In a blanket message sent to all Telegram users in Spain on Wednesday afternoon, the Russian technology entrepreneur accused Sánchez’s government of “pushing dangerous new regulations that threaten your internet freedoms”, adding that the measures could turn Spain “into a surveillance state under the guise of ‘protection’”. Durov claimed the mandatory age verification contained in the proposed legislation would set a precedent for tracking “EVERY user’s identity, eroding anonymity and opening doors to mass data collection”. He also said that holding tech executives liable for illegal, hateful or harmful content would encourage “over-censorship” and lead platforms to “delete anything remotely controversial to avoid risks, silencing political dissent, journalism, and everyday opinions”. “Telegram founder Pavel Durov used his unrestricted control of the app to send a mass message to all users in Spain, spreading several lies and making illegitimate attacks against the government. This is the first time this has happened in our country’s history,” they said. “Spaniards cannot live in a world where foreign tech oligarchs can flood our phones with propaganda at will simply because the government has announced measures to protect minors and enforce the law.” Durov was arrested in Paris in August 2024 as part of an inquiry into allegations of fraud, drug trafficking, organised crime, promotion of terrorism and cyberbullying. He was detained on suspicion of failing to take action to curb the allegedly criminal use of his platform and was eventually charged with 12 offences. He was later released under judicial supervision and has denied all the charges against him, describing his arrest as “legally and logically absurd” and saying investigators were “struggling to find anything that I or Telegram did wrong”. The Spanish government statement released on Wednesday said Durov had “deliberately designed a minimal moderation architecture that has turned Telegram into a recurring space for documented criminal activities such as child sex trafficking and drug trafficking”, with cases under investigation in Spain, France and South Korea. The French foreign minister Barrot praised the account’s strategy last month, saying: “The only right attitude, in the information war that has begun, is to raise our voice and to turn up the volume.” Sánchez has used X to push back at the platform’s owner, who is also chief executive of SpaceX. After Musk appeared to take issue with Spain’s recent plan to regularise 500,000 undocumented migrants and asylum seekers, the prime minister replied: “Mars can wait. Humanity can’t.” The French civil service minister David Amiel said the aim was “to put an end to the use of non-European solutions, to guarantee the security and confidentiality of public electronic communications by relying on a powerful and sovereign tool”. #durov#spain#barrot#telegram#harmful#content 📱American Оbserver - Stay up to date on all important events 🇺🇸
