painter Glade and have it generate C code with calls to the Gtk
GUI library, after that the only thing you have to implement are
the callbacks. One big advantage Gtk offers over other GUI
libraries is that it clearly separates the GUI construction
code from the callback code, this makes it very suitable for GUI
painters, i.e. the code the GUI painter generates doesn't have
to be changed manually. Another advantage of Gtk, from the
Haskell viewpoint, is that it was designed to work with other
languages. Quoted from the Gtk page:
GTK+ has been designed from the ground up to support a range of languages, not only C/C++. Using GTK+ from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development.
Although I haven't looked at the Haskell side in a while, everything
to go from Glade to a Haskell GUI should all be there:
http://www.gtk.org/
http://glade.gnome.org/
http://www.cse.unsw.edu.au/~chak/haskell/gtk/
The most recent version of Gtk+HS has support for libglade,
this means you can directly read the Glade XML file that
describes the GUI construction and the names of the
callback functions. To be honest I don't know how the
callbacks are actually connected to Haskell code, but there is
probably an example in the Gtk+HS distribution to show how
it works.
