cl-cffi-gtk is a Lisp binding to GTK+ 3 (GIMP Toolkit) which is a library
for creating graphical user interfaces. cl-cffi-gtk is licensed using the LGPL
which has been adopted with a preamble that clarifies the terms for use with
Lisp programs and is referred as the LLGPL.

This work is based on the cl-gtk2 library which has been developed by
Kalyanov Dmitry and already is a fairly complete Lisp binding to GTK+.

The focus of this work is to document the library more complete and to
do the implementation as consistent as possible. Most informations about GTK+
can be gained by reading the C documentation. Therefore, a modified version of
the C documentation from is included into the Lisp files to
document the Lisp binding to the GTK+ library. The API documentation is
available online at

Examples of the usage are included in a gtk-demo and tutorial examples. Start

Look at the wiki at for news
about the development of the library.

At this time, the library is developed and tested with SBCL 1.1.9 on a
Linux system (Ubuntu). Futhermore, the library is tested with Clozure Common
Lisp 1.9 and CLISP 2.49 on Linux. The minium version requirements are GTK+ 3.4
and GLIB 2.32.

The library compiles and runs under Windows 7, but when moving an application
window the application will freeze. This bug is not solved at this time.
