[MacRuby-devel] Implement PXSourceList in MacRuby

[Robert Lowe]

So long and thanks for all the fish.

Your implementation is wrong, it has nothing to do with macruby.

You skipped a bunch of code which is required to make it function.

For instance all SourceListItems must have children.

When you port  Objective-C code ensure you aren't skipping code or using rubyism (they may do difference things), port the code first then tweak it.

Regards,
 - Rob
