[MacRuby-devel] Visibility of ruby methods to objective-C delegates

Tue Feb 2 14:18:16 PST 2010

Hi Eloy,

it is not related to hotcocoa since my original application is not using it - this example was taken because
it was that simple that it fitted in some lines of code.

The question is rather, if I should attach a stripped down version of my app for better testing purposes.

Thanks,
Michael

If it does, then it might be a HotCocoa problem, in which case please file a ticket here: http://github.com/richkilmer/hotcocoa/issues
