[Rubycocoa-talk] newbie question: how to instantiate ruby object in InterfaceBuilder

[Hunter K. <re...@gm...>]

Hiya, I'm fairly new to Cocoa programming.  I'm using XCode +
Interface Builder, and have been working through "Cocoa Programming
for Mac OS X".

I'm a long time ruby fan, and have started playing around with the
RubyCocoa bindings.  Ruby and Objective-C look like a really natural
fit, and the binding seems really good.

However, I'm having a problem figuring out what I assume must be a
pretty simple thing - how do I make a Interface Builder "see" my ruby
classes, so I can create an instance of it, and tie it into the nib
file?

For example, I opened up the simpleapp example.  Interface Builder can
"see" AppController and MyView.  However, in XCode, if I create a new
Ruby subclass of NSObject, I can't figure out how to tell Interface
Builder about this new class.  If it were Obj-C, I'd just drag the .h
file onto Interface Builder, but when I try that with the .rb file
Interface Builder flicks over to the sounds tab or something.

What do I need to be able to do to make Interface Builder aware of my
Ruby classes?

Cheers,

Hunter
