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);
}

Pump result: Today's pump on Kucoin shocked us all with the massive volume, this was expected as we onboarded over 30,000 members in the past two weeks. However, due to unprecedented sell pressure from the #HALO team, we had expected a much larger rise in price. In fact internally we had discussed that we will be targeting around 900-1000% which we still tried to achieve with our team buying endless amounts after the first few minutes to guarantee that our members make good enough profit . Nonetheless, member's managed to profit over 150% during the signal, and with the support of our team we even managed to provide a second and third wave for extra profits which means anyone that has bought the dips during the signal had the chance to instantly make a lot of profits! We are receiving an overwhelming amount of positive messages from our community and we're happy to hear so many of you profited.
From this point on, our signals will only get stronger, and you can be confident that we will use all the power we have to keep reaching higher targets. As the majority of you are aware, our greatest pump to date generated a profit for our members of around 2000%, and now our primary focus is to see if we can repeat that sort of pump. It will be quite easy to accomplish with our existing power. It can happen once again if we don't face any sell pressure coming from the coin team itself which is something that can be hard to avoid at times, hopefully we can achieve that result once again on the next one. Stay tuned for the next pump announcement.
