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?
