'''java-gnome''' is a set of [[language binding]]s for the [[Java programming language]] for use in the [[GNOME]] [[desktop environment]]. It is part of the official GNOME language bindings suite and provides a set of [[Library (computing)|libraries]] allowing developers to write computer programs for GNOME using the Java [[programming language]] and the [[GTK]] cross-platform [[widget toolkit]].

== Development ==
{{Main|List of language bindings for GTK}}
Originally released on 08.10.1999 as version 0.2, it included the first bindings for [[GNOME|Gnome]] and [[GTK]]. Up until version 2.0, java-gnome was written by a project team.<ref>For the current list of developers see [http://java-gnome.sourceforge.net/4.0/AUTHORS.html AUTHORS] {{Webarchive|url=https://web.archive.org/web/20110208050648/http://java-gnome.sourceforge.net/4.0/AUTHORS.html |date=2011-02-08 }}</ref> The current version 4.0 was originally an internal project of {{usurped|1=[https://web.archive.org/web/20180415182128/http://www.operationaldynamics.com/ Operational Dynamics]}}, a [[change management]] consultancy group.<ref>java-gnome 4.0: [http://java-gnome.sourceforge.net/4.0/ About] {{webarchive|url=https://web.archive.org/web/20090721125223/http://java-gnome.sourceforge.net/4.0/|date=2009-07-21}}. Accessed 2009-08-31.</ref>

From 1999, the so-called 2.X series was the main project. After being abandoned by the main team for a time, the project was given to a new developer in 2006, due to development problems that came from many maintenance issues.<ref>{{Cite web|url=http://java-gnome.sourceforge.net/2.x/|title=java-gnome 2.x|date=2007-03-03|archive-url=https://web.archive.org/web/20070303030206/http://java-gnome.sourceforge.net/2.x/|access-date=2019-04-28|archive-date=2007-03-03}}</ref>

The last release of 2.0 versions (which continued the same project from version 0.2) was version 2.16.2 (called the 2.x series). The coverage of these series never made it past [[GTK]] 2.6. This update was declared as “end of life” for the old project and was no longer maintained, and any contribution patches for versions older than 4.0 are no longer accepted.

Both 2.0 and 4.0 updates have similar style of coding, while [[Java package|package]] spaces, [[Classes of computers|classes]], and [[Method (computer programming)|method names]] are different. Internals of project were changed from version 4.0, so they can't be accessed publicly.<ref>{{Cite web|url=http://java-gnome.sourceforge.net/2.x/|title=java-gnome 2.x|date=2007-03-03|archive-url=https://web.archive.org/web/20070303030206/http://java-gnome.sourceforge.net/2.x/|access-date=2019-04-28|archive-date=2007-03-03}}</ref>

Currently, the project is maintained by "[https://launchpad.net/~java-gnome Java-gnome hackers]". The leader of this latest team is {{usurped|1=[https://web.archive.org/web/20120608040437/http://www.operationaldynamics.com/about/staff/andrew/ Andrew Cowie]}}, one of the principal architects for the java-gnome project.<ref>{{Cite web|url=https://launchpad.net/~afcowie|title=Andrew Cowie in Launchpad|website=launchpad.net|date=12 February 2008 |access-date=2019-04-28}}</ref><ref>{{Cite web|url=http://java-gnome.sourceforge.net/AUTHORS.html|title=AUTHORS|website=java-gnome.sourceforge.net|access-date=2019-04-28|archive-date=2023-06-01|archive-url=https://web.archive.org/web/20230601225617/https://java-gnome.sourceforge.net/AUTHORS.html|url-status=dead}}</ref>

== Functions ==
Java-gnome uses Java programming language and [[Java (programming language)|Java]] based class system for creation of [[Graphical user interface|GUI]] parts. Each implemented package has a different function; packages used in version 4.0 are:<ref>{{Cite web|url=http://java-gnome.sourceforge.net/doc/api/4.1/|title=java-gnome 4.1.3 API Documentation|website=java-gnome.sourceforge.net|access-date=2019-04-28}}</ref>

* [[GTK]] - The widget toolkit itself.
* [[GDK]] - Contains low level drawing primitives. The majority of drawing is done by Cairo.
* [[GLib|Glib]] and [[GObject|Gobject]] - Containers for the rest of infrastructure that allow the use of OOP.
* [[Pango]] - Text layout engine.
* [[Accessibility Toolkit|ATK]] - Accessibility toolkit that allows extra control with computer controls.
* [[GtkSourceView]] - Source code highlighter.
* [[LibNotify]] - Warning notifier.
* [[GtkSpell]] - Spellchecker.
* [[LibUnique]] - Library that helps to maintain one working instance of an application.

== Support ==
Java-gnome is only supported in Linux and Unix distributions, unlike most other [[GTK]] bindings, that are supported by other systems. Distribution specific instructions are available for:

* [[Gentoo Linux|Gentoo linux]]
* [[Arch Linux|Arch linux]]
* [[Debian|Debian linux]]
* [[Ubuntu|Ubuntu linux]]

Semi-finished instructions are available for [[OpenSolaris|Open Solaris]] and [[Fedora (operating system)|Fedora Core Linux]] distributions.

== Licensing ==
Java-gnome is [[free software]] released under the terms of the [[GNU General Public License|GNU General Public License version 2]].<ref>{{Cite web|url=http://research.operationaldynamics.com/bzr/java-gnome/mainline/COPYING|date=2017-07-04|archive-url=https://web.archive.org/web/20170704205150/http://research.operationaldynamics.com/bzr/java-gnome/mainline/COPYING|access-date=2019-04-28|url-status=usurped|archive-date=2017-07-04}}</ref>

== Example ==
To compile a java-gnome class it's necessary to add the gtk-4.1.jar jar in the classpath. The jar is available on [[Debian]] (and all Debian-based distributions) in the libjava-gnome-java<ref>[http://packages.debian.org/jessie/libjava-gnome-java libjava-gnome-java package]</ref> package, which can be found in the official repositories (the jar is installed under the /usr/share/java path).
