-- This file reflects the Gtk+ object hierarchy in terms of Haskell classes.
--
-- Note: the mk... functions were originally meant to simply be an alias
-- for the constructor. However, in order to communicate the destructor
-- of an object to objectNew, the mk... functions are now a tuple containing
-- Haskell constructor and the destructor function pointer. This hack avoids
-- changing all modules that simply pass mk... to objectNew.
