Guides or samples for NSRuleEditor?

Question

NSRuleEditor looks like a pretty powerful class and it looks like stuff like iTunes Smart Playlists or Finder Smart Folders are using it.
(I reckon it should be called NSSmartRuleEditor...)

But is there any kind of documentation apart form the reference?

Some kind of sample code or guide would be nice but it doesn't look like ADC has anything to offer.. as of now NSRuleEditor seems to be the least documented control in Cocoa!

Anybody knowing of any Open Source projects using the controls, blog articles, etc.?

Wow, that popular, ey? :-) – Peralta

I can't post anything useful now (I will do tomorrow), but I did find an example project on either MacOSX.com or MacRumors.com forums. – Sag

much appreciated - still no sample code found yet.. – Peralta

Ahem... A few months later, github.com/danieljfarrell/NSRuleEditorTest – Sag

I think you should probably be looking for NSPredicateEditor rather than NSRuleEditor. NSPredicateEditor is a subclass of NSRuleEditor and is what is used for editing "smart" playlists and the such.

NSPredicateEditor isn't terribly difficult to use. I have found many other examples on StackOverflow as well. Here's a good example: #5643181 – Lyons
