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

🚀 Whale Investor Faces Losses on Iran Regime Prediction A significant investor, identified by the address 0xa7d1...b824, has incurred a loss of $345,000 after investing $527,000 in a prediction that the Iranian regime would collapse by June 30. According to Odaily, this investor previously placed $176,000 on a prediction that the U.S. military would invade Iran by March 31 and $148,000 on the regime's collapse by the same date, both of which did not materialize. The market's criteria for a 'yes' outcome are stringent, requiring the dissolution, paralysis, or replacement of Iran's current governing system, including the Supreme Leader's office, the Guardian Council, and the Revolutionary Guards led by clergy, by June 30, 2026. This must be confirmed by a consensus among recognized authoritative media, indicating the regime has lost control over the majority of the population. The rules specify that regular political elections, internal reforms, or power transitions do not meet the criteria. Even an internal coup retaining the core structure of the Islamic Republic would result in a 'no' settlement. Additionally, the loss of some territory or challenges from anti-government forces would not constitute a 'collapse' unless it prevents the regime from governing the majority of the population. #Investment#Iran#RegimeChange#PredictionMarket#FinancialLoss#Cryptocurrency#Politics
