Actually, Qt (as in Qt Widgets) is a peculiar case. Qt draws its own widgets, but on some platforms uses native theming APIs to draw widgets (e.g. HITheme in macOS[1]). Though they are apparently experimenting with native widgets now [2]. So I'd say Qt is more native than e.g. Electron, but it is definitely not completely native. Except on Linux of course.
