Main article: List of language bindings for GTK+

java-gnome is a set of language bindings 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 libraries allowing developers to write computer programs for GNOME using the Java programming language and the GTK+ cross-platform widget toolkit.

Up until version 2.0, java-gnome was written by a project team, the current version 4.0 was originally an internal project of Operational Dynamics, a change management consultancy group. This new version is a complete re-write of java-gnome and was originally written for creating business tools to the company's clients, but eventually grew into a full replacement Java language binding for GNOME.

Unlike most other GTK+ bindings, there is no version available for Microsoft Windows.

Java-gnome is free software released under the terms of the GNU General Public License.

Example

To compile a java-gnome class it's necessary to add in the classpath the jar gtk-4.1.jar, it's disponibile on Debian (and all Debian-based distributions) on package libjava-gnome-java on official repositories (the jar is installed on path \usr\share\java\).
