Sean,
   I implemented what you have above but there seems to be a problem.  
In my NSDocument Subclass, PFDocument, in the  
windowControllerDidLoadNib method I call:

[vtkView finalInit];

Except that vtkView is still nill at that point. Which is kinda weird  
since I know the constructor has already been called so the reference  
in my PFDocument must not have been set yet. Are you over riding some  
other method in your NSDocument Subclass? Or maybe I am missing some  
hook up in Interface builder?

If I put everything in the vtkCocoaGLView Subclass constructor then I  
get a warning "invalid drawable" when       _interactor->Initialize 
();  is called. The warning seems to be harmless, but I would like  
something that didn't produce warnings.

Maybe there is another method in vtkCocoaGLView that could be  
implemented or over ridden where this stuff can be hooked up?

Thanks for any help.
