G

GDK

GTK+ Drawing Kit. GTK+ calls GDK to draw widgets on the display. GDK is independent of a back end such as X11 , Windows, or framebuffer , making it easier to port GTK+ to other platforms.

GIMP

The GNU Image Manipulation Program. A powerful image-processing package that uses (and originated) GTK+. GIMP was one of first popular high-performance open -source user programs.

Glade

A graphical application for building graphical user interfaces. Glade supports widgets and components from GTK+, Bonobo, and GNOME.

GLib

A low-level library used by many other libraries, including GTK+ and the GNOME system. GLib offers efficient platform-independent modules for relatively low-level system tasks , such as multithreading and memory block access, as well as conventional data structure support (lists, trees, and so on).

GNOME

GNU Network Object Model Environment. This acronym is now somewhat irrelevant, because GNOME was originally a network-transparent object model (now Bonobo ). GNOME is three things: a set of development libraries for software development, a desktop software environment package, and the community that uses and develops the system.

GNOME-Print

The GNOME interface for printing and anything related to printing. GNOME-Print supplies a number of graphics primitives for drawing on a virtual canvas and then takes over the hard part of guiding a document through the maze of software and hardware required to put an image on real paper.

GnomeVFS

GNOME Virtual File System. A network-transparent library for file access; it supports asynchronous access, coupling of MIME types to actions, and other common file operations.

GObject

The GLib object system; an object-oriented implementation for programming languages that have no native object support. GObject manages all object information and operations at run time.

gravity

Describes the behavior of a mark in a text buffer (for example, the cursor) when text is inserted at the mark. Left gravity means that the mark goes before the new text; right gravity means that the mark moves after the text.

GSignal

The GObject signal implementation.

GTK+

GIMP Toolkit. Originally a part of GIMP as a free replacement for the Motif toolkit, this library soon took on a life of its own. GTK+ is now ranks with Qt as one of the most popular toolkits for programming applications in the X Window System.

GType

The GObject type system. GObject uses GType to advertise the types that exist, the properties that the types have, and the relationships between types.

GValue

An encapsulation system for values of various types. You can use a GValue in any place where you might use an untyped pointer but do not wish to lose the type information.

GUI

Graphical user interface.
