Media.Streaming.GStreamer.Core.MiniHierarchy
Description
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.
