Hello list folks,

I'm struggling with the abstraction and sketchy documentation that surround 
NSRuleEditor. I feel a need to know that the effort is worthwhile, versus 
cobbling together something in a table or outline view instead.

The domain I am working in really fits well within the structured rule editor 
model. I have many lists of finite scope which have an inherent hierarchy and 
each choice made implies filters for the remaining options.

But I am really confused by the highly flexible model of the rule editor. The 
toughest part right now is that I am unable to see how the NSRuleEditor 
instance populates a given row, based on having received either a stringValue, 
a menuItem or a control/view.  Where in all of this have I the opportunity to 
establish the layout and orientation of the various widgets for a given row?  

One example I have found (NibBasedSpotlightSearcher.xcodeproj - circa 2006) 
presents a window in the nib which holds clusters of related controls in a 
single view. I'm doing the gasping guppy trying to see where in the code those 
individual controls are addressed, loaded and applied. 

Has anyone got a nakedly simple example of a minimalist use of the NSRuleEditor 
they could point me to? 

Cheers,
Erik
