“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.”
