Thanks. That's what I wanted to know - I thought the docs suggested maybe you could pass objects in (other than owner)
> Furthermore, from your further description it sounds like what you’re referring to as a “view” is actually a subclass of NSWindowController; it knows how to load a nib file already, so you should just leverage that rather than try to do it all yourself by hand.
Thanks again. It's an "ultra-thin gui" a-la Dave Astels' TDD: A Practical Guide (originally Mike Feathers' Humble dialog). There is another controller class that handles all the logic. This class just delegates the actions and outlets from Cocoa, so from my app's perspective, it's a view, but from cocoa's perspective, it's a controller. It think it should be just an NSObject (that's what I've seen in all the books and there's only one window in my app). I made it an NSWindowController in the process of trying to get it to load the nib (which is only for testing) and forgot to set it back. Is there a reason to keep it an NSWindowController?
I ended up with the following that loaded the nib successfully in the test:
NSApplication.sharedApplication
top_level = []
context = NSDictionary::dictionaryWithObjects_forKeys [NSApp, top_level], [NSNibOwner, NSNibTopLevelObjects]
@@NibPath = "/path/to/MainMenu.nib"
OSX::NSBundle::loadNibFile_externalNameTable_withZone @@NibPath, context, NSApp.zone
objects = context['NSTopLevelObjects']
view = objects.find { |obj| obj.class == object_type }
