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);
}
