The problem is that I actually have a lot arrays of lots of objects each with a number of different properties that can be displayed in more than one way (all dependent on one preference settings). Putting these through proxies/proxy arrays so that I can use bindings and KVO to make process automatic sounds like a terribly painful way to go - plus it defeats the purpose of bindings a little (glue code wise).
Can you not trigger the update by making the object property (temperature) KVO-dependent on the preference setting? I don't mean the object property's value, just the property itself. Either use keyPathForValuesAffectingTemperature (or whatever) in the class that has the property, if it can get to the preference setting via keypaths, or else call will/didChangeValueForKey:@"temperature" (or whatever) from some controller that monitors the preferences.
That way, a change to the preference will trigger notifications from the temperature property, even though its untransformed value hasn't changed, causing the user interface to update with the transformed value.
Or something like that. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
