# Quick Module Overview

This appendix provides a quick overview of the libraries included in the GNOME desktop and developer platform. Libraries are listed by module with a brief description and a link for more information in this document, where possible.

## Platform Modules

Modules in the GNOME developer platform make strict guarantees about API and ABI stability. Applications developed against platform modules can be assured of running unmodified for the duration of the GNOME 2 lifecycle.

GConf

  GConf provides the daemon and libraries for storing and retrieving configuration data. GConf is discussed in .

ORBit

  ORBit is a deprecated CORBA server. GNOME's deprecated component architecture, Bonobo, is built on top of CORBA. CORBA is discussed in .

atk

  ATK provides the set of accessibility interfaces that are implemented by other toolkits and applications. Using the ATK interfaces, accessibility tools have full access to view and control running applications. ATK is discussed in .

gail

  GAIL provides an implementation of the ATK interfaces for GTK+ and GNOME libraries, allowing accessibility tools to interact with applications written using these libraries. In 2009 GAIL was moved into GTK+. Accessibility is discussed in .

gio

  A part of GLib, the GIO library provides a high-level API for accessing files and folders. Together with the GVFS library, it provides a file system abstraction that allows transparent access to local and remote files. GIO is discussed in .

glib

  GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures.

gnome-vfs

  GnomeVFS is a deprecated library for accessing files and folders. It is superseded by GIO and GVFS. Newly written code should use GIO instead.

gtk+

  GTK+ je základní knigovnou používanou v GNOME pro tvorbu uživatelského rozhraní aplikací. Poskytuje grafické obládací prvky a obsluhu signálů pro práci s uživatelským prostředím. Knihovnu GTK+ probírá .

gvfs

  GVFS provides a backend implementation for GIO, allowing access to numerous protocols with the GIO API. Developers do not access GVFS directly. Instead, applications written with GIO will automatically use GVFS on systems where it is enabled.

libIDL

  libIDL is a deprecated library for parsing Interface Definition Language (IDL) files, which are necessary for CORBA interfaces. libIDL is used by GNOME's deprecated CORBA implementation, ORBit. CORBA is discussed in .

libart_lgpl

  libart is a deprecated graphics library which can render vector paths. It is used by the GnomeCanvas widget. Newly written code should not use libart_lgpl and instead use Cairo and/or other technologies.

libbonobo

  Bonobo is a deprecated framework for creating reusable components for use in GNOME applications, built on top of CORBA. Bonobo is discussed in .

libbonoboui

  The deprecated Bonobo UI library provides a number of user interface controls using the Bonobo component framework. Bonobo is discussed in .

libglade

  Libglade is a deprecated library for constructing user interfaces dynamically from XML descriptions. Libglade has been deprecated in favor of GtkBuilder. Libglade allows programmers to construct their user interfaces using a graphical interface builder application, and then import those interface definitions. Libglade is discussed in .

libgnome

  The deprecated libgnome library provides a number of useful routines for building modern applications, including session management, activation of files and URIs, and displaying help.

libgnomecanvas

  The GnomeCanvas widget provides a flexible widget for creating interactive structured graphics.

libgnomeui

  The deprecated libgnomeui library provides additional widgets for applications. Many of the widgets from libgnomeui have already been ported to GTK+.

libxml2

  The libxml2 library provides a number of APIs for working with XML in a standards-compliant manner. The libxml2 library is discussed in .

libxslt

  The libxslt library provides a fast and complete implementation of XSLT, a language for transforming XML. The libxslt library is discussed in .

pango

  Pango je základní knihovna používaná v GNOME pro práci s texty a písmy. Obsahuje širokou posporu různých způsobů zápisu používaných ve světě. Knihovnu Pango probírá .

## Moduly pracovní plochy

Modules in the GNOME desktop are not required to make the same API and ABI stability guarantees as modules in the platform, although attempts are made to keep them relatively stable. Often, modules are introduced in the desktop release to mature, and are moved into the platform once they've stabilized.

eel

  The eel library provides a number of additional widgets primarily for use inside Nautilus, the GNOME file manager. Many of the widgets in eel have since been provided in GTK+.

evolution-data-server

  Evolution Data Server provides a unified location for address book and calendar information, allowing multiple applications to share the same data. Evolution Data Server is discussed in .

gnome-panel

  In addition to the actual panel, the gnome-panel package provides the libraries used to construct panel applets to run on the user's panel. Panel applets are discussed in .

gnome-keyring

  Správce klíčenek pro GNOME poskytuje moderní a bezpečný způsob ukládání uživatelských hesel a dalších citlivých údajů. Klíče jsou šifrovány a lze k nim přistupovat jen s výslovným souhlasem uživatele. Správce klíčenek probírá .

gstreamer

  GStreamer is the powerful multimedia used throughout GNOME to play, create, and manipulate sound and video. GStreamer is discussed in .

gtkhtml

  Knihovna gtkhtml přináší podporu pro odlehčené renderování jazyka HTML spolu s plnou podporou úprav bohatých textových dokumentů (rich text). Klient elektronické pošty Evolution ji využívá k tvorbě a prohlížení HTML uživatelem.

gtksourceview

  The gtksourceview library provides an extension of the GtkTextView widget with support for automatic syntax highlighting and other functions that are useful for source code editors. It is used in the gedit text editor.

libgail-gnome

  GAIL poskytuje implementaci rozhraní ATK pro knihovny GTK+ i GNOME, umožňuje nástrojům přístupnosti komunikovat s aplikacemi, které jsou pomocí těchto knihoven napsány. Přístupnost probírá .

libgnomeprint

  libgnomeprint is a deprecated library that provides an implementation of the PostScript imaging model. It is superseded by GtkPrint. Newly written code should use GtkPrint instead. The GNOME print framework is discussed in .

libgnomeprintui

  libgnomeprintui is a deprecated library that provides a standard print dialog, a print preview dialog, and various other controls required for printing. It is superseded by GtkPrint. The GNOME print framework is discussed in .

libgtop

  The libgtop library provides a portable API for obtaining information about running processes. It is used in the System Monitor application.

librsvg

  The librsvg library provides an implementation of Scalable Vector Graphics (SVG). It is used throughout the desktop to render resolution-independent vector graphics.

libsoup

  The libsoup library provides an implementation of the Simple Object Access Protocol (SOAP), as well as an HTTP implementation. SOAP can be used to build web services into applications. The libsoup library is discussed in .

libwnck

  Knihovna libwnck nabízí možnost ovládat libovolného správce oken, který je vytvořen dle specifikací EWMH. Příkladem je Metacity, výchozí správce oken v prostředí GNOME. Knihovnu libwnck popisuje .

libxklavier

  The libxklavier library provides a high-level API for accessing and setting keyboard layouts. It is used in the Keyboard Preferences to allow users to set their keyboard layout and options.

vte

  VTE je widget emulace terminálu, který lze použít c palikacích napsaných pod GTK+. Poskytuje konzistentní API a využívá pro vykreslování textu Pango, což zajišťuje zobrazení obsahu v národních jazycích. VTE používá Terminál GNOME.
