Something like "validation," only not?


  • Subject: Something like "validation," only not?

My app presents a table of values to the user. The table has two columns, "name" and "value," which are managed by an NSDictionaryController bound to an NSDictionary. I have enabled my users to edit these values (their changes propagate back to the underlying NSDictionary, and I can then do whatever it is I planned to do with the new values). But I would like to add some user feedback (changed values are bold, or red, or flashing thirteen times a second, something like that), as well as enabling/disabling a "save" button I've provided, depending on whether any of the values have been changed.

I think this might be a case for "Validation." Only, my reading on validation only takes it as far as enabling/disabling controls (the Save-button case); it does not seem to extend to other kinds of UI actions, such as changing the display font.

Is the "change the appearance" case buried somewhere in Validation, and where should I dig that I apparently missed? Or, if this is not "Validation," what is it and where do I read more?
