Depending only on GLib and libc, GObject is a cornerstone of GNOME and is used throughout GTK, Pango, ATK, and most higher-level GNOME libraries like GStreamer and applications. Prior to GTK+ 2.0, code similar to GObject was part of the GTK codebase. (The name “GObject” was not yet in use — the common baseclass was called GtkObject.)
