I may have bitten off more than I can chew, but I'm trying to use
NSRuleEditor as a component to define and edit a Foundation data
structure (general purpose tree of NSArray, NSDictionary, NSNumber
etc.). This might be re-purposing the class a little and it certainly
has little to do with predicates, but the user interaction is a good
fit for what I want.
There seems to be very little information around about NSRuleEditor if
it's not tied to predicates, particularly when it comes to
subclassing. I haven't figured out how to make this work at all, so
I'm currently relying on a delegate and a binding to the 'rows'
property of the same delegate.
So my question: does anyone have any examples of _subclassing_
NSRuleEditor?
I'm thinking that I could make the current delegate a subclass of
NSRuleEditor, have it bind to itself and set itself as delegate, but
then I need to hide the -setDelegate from the user. It sounds a bit
icky, but I definitely don't want to be relying on internals that
might change - so If anyone has any suggestions, I'd be grateful.
Paul.
