Nothing, it happens automatically. Our Theme has key: "kde" matching to XDG_CURRENT_DESKTOP https://invent.kde.org/plasma/plasma-integration/-/blob/master/qt6/src/platformtheme/kdeplatformtheme.json?ref_type=heads QGuiApplication will first try to load a matching plugin directly only afterwards via QPlatformIntegration::createPlatformTheme which calls QGenericUnixTheme::createUnixTheme https://invent.kde.org/qt/qt/qtbase/-/blob/dev/src/gui/kernel/qguiapplication.cpp#L1369 David
