Hi, This has probably been asked a zillion times, but I can't find it. How can I theme my qt4 app? Not all qt4 apps, just this one. I tried "export QT_STYLE_OVERRIDE=macintosh ./project1", but that didn't have an effect. I can do it with QApplication_setStyleSheet(App, at stylesheet);, but App is private in TQtWidgetSet. So probably I'm missing something. Mattias
