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/Articles/ocrtTypeEncodings.html
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.
HTH,
Laurent
