Hi Bulat,
afaik, there are just two good enough libs - wxHaskell and GtkHs. can anyone point (or write) detailed comparison of their features? i plan to write large GUI program in Haskell and want to select best one. the requirements that i can imagine at this moment is the following:
I used to use wxHaskell. I wanted to write a GUI program using GHC 6.4.2 and was (disturbingly) shocked to find out that _neither_ of the GUI toolkits had prebuilt packages that worked on Windows with GHC 6.4.2. I complained and within a day Duncan had done one for Gtk2Hs, and to my knowledge wxHaskell still doesn't have such a packaged version. For this reason, I would recommend Gtk2Hs - the level of support and maintainership is far better than wxHaskell at the moment. I appreciate wxHaskell has new maintainers, but when picking a GUI toolkit where you can't easily switch later, currently maintained is a big bullet point for me! Thanks Neil
