You can define your own mapping within your app or extend the existing ones, delegation can also be added on each instance of any object.
Here is a sample app I wrote with a custom mapping (which was later on merged in HotCocoa): http://github.com/mattetti/macruby-examples/blob/fe06617645c8809183fb15bca025016937e1c84b/download/lib/progress_indicator.rb You can see that I defined my mapping like any other mappings and just required the file in my application.rb file: http://github.com/mattetti/macruby-examples/blob/fe06617645c8809183fb15bca025016937e1c84b/download/lib/application.rb#L5 - Matt 2009/3/16 Jeff Cohen <cohen.j...@gmail.com> > Hi Laurant, > > Thanks a lot for your reply.
