The Banana User Interface (BUI) toolkit is built atop the jMonkeyEngine (JME), a 3D engine for Java that is currently built on top of LWJGL. BUI aims to provide an interface toolkit with the following characteristics:

• A component hierarchy and event dispatch model familiar to users of Swing and the AWT
• An easily customizable look and feel to allow game developers the necessary flexibility to create an interface consistent with their game's art style
• As full-featured as possible a user experience, providing standard UI functionality such as focus, cut and paste, keyboard navigation and control and so forth (we have a long way to go on this front)
• An open source license that allows the toolkit to be used and extended at no cost by developers working on personal and commercial projects

Note

BUI has long since been retired. JME has gone through multiple major releases since BUI was last maintained. The developers of BUI have put their efforts into a new engine, with accompanying user interface toolkit (which has its origins in the BUI source code), called Clyde.
