The QGtkStyle class provides a widget style rendered by GTK+
The QGtkStyle style provides a look and feel that integrates well into GTK-based desktop environments such as the XFCe and GNOME.
It does this by making use of the GTK+ theme engine, ensuring that Qt applications look and feel native on these platforms.
Note that this is Qt 4, I'm too lazy to check the Qt 3 docs right now, but they're on the same site.
