Qt Jambi

Qt Jambi is a Java binding of the cross-platform application framework Qt. It enables Java developers to use Qt within Java programming language. In addition, Qt Jambi generator can be used to create Java bindings for other Qt libraries and future versions of Qt. Unlike GTK there are no Swing LAF implementations that use Qt for rendering.
Qt Jambi supports Linux and other flavours of Unix such as macOS, as well as Microsoft Windows.
Official support for Qt Jambi by Nokia ended in March 2010, and the project is now maintained by an open source community.
