The GNOME environment uses GTK+ asbase, which means that programs writtenGNOME use GTK+ as their toolkit. GNOME applicationsnotonly programs using it, though,any GTK+ program (or GNOME program,that matter) can run on topother desktop environments, such as KDE or XFce. The GPE Palmtop Environmentanother environment that uses GTK+ asbase.
GTK+ initially contained some utility routines that were not strictly graphics-related,instance providing such data structures as linked listsbinary trees. This has now been separated intoseparate library, Glib, whichregularly useddevelop programs that do not havegraphical interface.
GTK+ 2,successorGTK+, uses Pango as its text rendering engine.
