GTK is a toolkit for creating graphical user interfaces. It is part of the GNU Project and maintained by GNOME.
Users can install the GTK libraries with the following command:
emerge --ask x11-libs/gtk+
Some applications may optionally be built with support for a GTK interface when enabling the
gtk USE flag.
Users may even choose to enable GTK support for all packages in /etc/portage/make.conf.
The following programs can be used to change the appearance of applications using the GTK toolkit:
