Ah cool. Thanks for the response. Is there any documentation on the possible values you can hand to the "new_with_type" method? What does that '@' sign mean?
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjCRuntimeGuide/A... In the case of a C structure, you can call the #type class method on the struct class. $ macirb irb(main):001:0> framework 'Foundation' => true irb(main):003:0> NSRect.type => "{CGRect={CGPoint=dd}{CGSize=dd}}" The next version of MacRuby will have a better Pointer class which will accept symbols like :int, :object, etc., but in the meantime you need to pass the Objective-C types.
