wxHaskell is a portable and native GUI library for Haskell. The goal of the project is to provide an industrial strength GUI library for Haskell, but without the burden of developing (and maintaining) one ourselves.

wxHaskell is therefore built on top of wxWidgets – a comprehensive C++ library that is portable across all major GUI platforms; including GTK, Windows, X11, and MacOS X. Furthermore, it is a mature library (in development since 1992) that supports a wide range of widgets with the native look-and-feel, and it has a very active community (ranked among the top 25 most active projects on sourceforge).

Status

Since the core interface is generated automatically from the wxEiffel binding, about 90% of the wxWidgets functionality is already supported, excluding more "exotic" widgets like dockable windows. Most work is currently directed into writing a Haskellized version of the wxWidgets API. The library currently supports Windows, GTK (Linux) and MacOS X.
