Theme engine using TQt for GTK+ 2.x and Trinity The GTK-Qt Theme Engine (also known as gtk-qt-engine) is a GTK 2 theme engine that calls TQt to do the actual drawing. This makes your GTK 2 applications look almost like real TQt applications and gives you a more unified desktop experience. Please note that this package is targeted at Trinity users and therefore provides a way to configure it from within KControl.
