Due to popular demand, the new SOE implementation based on Gtk2Hs is now available separately: http://haskell.org/~duncan/soegtk-0.9.10.tar.gz http://haskell.org/~duncan/soegtk-0.9.10.zip or darcs get http://haskell.org/~duncan/soegtk/ It works with the latest released version of Gtk2Hs, ie version 0.9.10 It works at least on Linux and Windows. It's packaged with Cabal. The rendering quality is better than the original HGL version. Here's a side-by-side comparison: http://haskell.org/~duncan/gtk2hs/SOE-cairo.png and it works with GHC on Windows, which the original doesn't. Sadly it doesn't work with Hugs98 (but I hear that the HGL version does work with Hugs98). There may be some slight differences in the semantics from the original. Please test it with any SOE examples you've got. If you find any mismatches, then report them as bugs here: http://hackage.haskell.org/trac/gtk2hs/newticket Enjoy. Duncan
