Hi all, I am trying to write a text editor for Mac OS X. I want to have multiple documents in a single window organized by tabs. However, I am stumped when it comes to implementing this with regard to Multiple Document Architecture. Are there any open source mac apps that allow you to open multiple documents in a single (possibly tabbed) window? I believe looking at the source code would help me. However, the only app that fits this description that I have found is Smultron which (as far as I can tell) is not document-based but rather uses Core Data to manage documents, which is not what I am looking for. Thanks.
