[MacRuby-devel] Quartz 2D Graphics problem

[Steve Clarke]

Hi,

While you can't mix and match within one file, I think you can have a Class that contains both Objective C methods and Macruby methods each defined in their own file.  Objective C classes are open and the Macruby methods will be added to them.
