“The GTK-Qt Theme Engine (also known as gtk-qt-engine) is a GTK 2 theme engine that calls Qt to do the actual drawing. This makes your GTK 2 applications look almost like real Qt applications and gives you a more unified desktop experience. Please note that this package is targeted at KDE users and therefore provides a way to configure it from within KControl.” Personaly i am using this package. And it’s works cool
