Dark Mode for QT Application

With dark mode becoming quite fast the default setup for many, I figured having it in the new QText wouldn't hurt. And with QT it's easy - surprisingly so. Just start with a good style (i.e. Fusion) and adjust its palette. And that's all it took.

Code  Copy
qApp->setStyle(QStyleFactory::create("Fusion"));

QPalette newPalette;
newPalette.setColor(QPalette::Window,          QColor( 37,  37,  37));
newPalette.setColor(QPalette::WindowText,      QColor(212, 212, 212));
newPalette.setColor(QPalette::Base,            QColor( 60,  60,  60));
newPalette.setColor(QPalette::AlternateBase,   QColor( 45,  45,  45));
newPalette.setColor(QPalette::PlaceholderText, QColor(127, 127, 127));
newPalette.setColor(QPalette::Text,            QColor(212, 212, 212));
newPalette.setColor(QPalette::Button,          QColor( 45,  45,  45));
newPalette.setColor(QPalette::ButtonText,      QColor(212, 212, 212));
newPalette.setColor(QPalette::BrightText,      QColor(240, 240, 240));
newPalette.setColor(QPalette::Highlight,       QColor( 38,  79, 120));
newPalette.setColor(QPalette::HighlightedText, QColor(240, 240, 240));

newPalette.setColor(QPalette::Light,           QColor( 60,  60,  60));
newPalette.setColor(QPalette::Midlight,        QColor( 52,  52,  52));
newPalette.setColor(QPalette::Dark,            QColor( 30,  30,  30) );
newPalette.setColor(QPalette::Mid,             QColor( 37,  37,  37));
newPalette.setColor(QPalette::Shadow,          QColor( 0,    0,   0));

newPalette.setColor(QPalette::Disabled, QPalette::Text, QColor(127, 127, 127));

qApp->setPalette(newPalette);

PS: Ok, chances are that you will need another iconset but that's the story for some other time.
