XForms is a GUI toolkit based on Xlib for X Window Systems. It features a rich set of objects, such as buttons, sliders, and menus etc. integrated into an easy and efficient object/event callback execution model that allows fast and easy construction of X-applications. In addition, the library is extensible and new objects can easily be created and added to the library. See xformsd package for developement related files.
