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

‍#song @fluencyinenglish ❇️What If I Was Nothing 🔹Song by All That Remains Just let it go, don’t want to haunt you anymore I can’t be sure I know just what we’re fight for I know that you’re scared and that you’re thinking I may go I’m not leaving, I’m not leaving @fluencyinenglish And if you’re thinking I might, might be lead astray Just remember this one question What if I was nothing, what if this is true? What if I was nothing, girl, nothing without you So what if I was angry, what did you think I’d do? I told you that I love you, girl, I’m nothing without you @fluencyinenglish I know it’s hard, it seems that we’ve worked at this so long Soft and foolish pride that tells us we’re not wrong I hear your voice, you tell me that you’ll never go And I believe it, I believe it And if you’re thinking I might, might be lead astray Just remember this one question @fluencyinenglish What if I was nothing, what if this is true? What if I was nothing, girl, nothing without you So what if I was angry, what did you think I’d do? I told you that I love you, girl, I’m nothing without you And we can keep this going on, we’ll make it work some way And every step, it makes us stronger every day And if you’re thinking I might, might be lead astray Just remember this one question @fluencyinenglish What if I was nothing, what if this is true? What if I was nothing, girl, nothing without you So what if I was angry, what did you think I’d do? I told you that I love you, girl, I’m nothing without you @fluencyinenglish What if I was nothing, what if this is true?

‍#song @fluencyinenglish A Showman's Life George Strait A showman's life is a smokey bar And the fevered chase of a tiny star It's a hotel room and a lonely wife From what I've seen of a showman's life Nobody told me about this part They told me all about the pretty girls And the wine and the money and the good times There's no mention of all the wear and tear On an old honky tonker's heart Well I might have known it But nobody told me about this part A boy will dream, as children do Of a Great White Way, until the dream comes true And a phony smile in a colored light Is all there is to a showman's life Nobody told me about this part They told me all about the pretty girls And the wine and the money and the good times There's no mention of all the wear and tear On an old honky tonker's heart Well I might have known it But nobody told me about this part And nobody told me about this part They told me all about the pretty girls And the wine and the money and the good times There's no mention of, all the wear and tear On an old honky tonker's heart Well I might have known it But nobody told me about this part Well I might have known it Nobody told me about this part Songwriters: Jesse Winchester @fluencyinenglish

‍#song @fluencyinenglish @ieltsstrategies ✴️Better Than I Used to Be Genre: Country Artist: Tim McGraw I know how to hold a grudge I can send a bridge up in smoke And I can't count the people I've let down, the hearts I've broke You ain't gotta dig too deep If you wanna find some dirt on me But I'm learning who you've been Ain't who you've got to be It's gonna be an uphill climb Aw honey I won't lie @fluencyinenglish @ieltsstrategies I ain't no angel I still got a still few more dances with the devil I’m cleanin' up my act, little by little I’m getting there I can finally stand the man in the mirror I see I ain’t as good as I’m gonna get But I’m better than I used to be I’ve pinned a lot of demons to the ground I’ve got a few old habits left But there’s one or two I might need you to help me get Standin' in the rain so long has left me with a little rust But put some faith in me And someday you’ll see There’s a diamond under all this dust @fluencyinenglish @ieltsstrategies I ain't no angel I still got a still few more dances with the devil I’m cleanin' up my act, little by little I’m getting there I can finally stand the man in the mirror I see I ain’t as good as I’m gonna get But I’m better than I used to be I ain't no angel I still got a still few more dances with the devil But I’m cleanin' up my act, little by little I’m getting there I can finally stand the man in the mirror I see I ain’t as good as I’m gonna get But I’m better than I used to be Songwriters: Bryan Simpson / Ashley Gorley @fluencyinenglish @ieltsstrategies
