First, you need to stop using KVO for this. As I said before, NSTextField is not documented to be KVO complaint for any of its properties, so you cannot observe it. To use -controlTextDidChange:, you would have to move your core logic that updates the other text fields out to a common place that can be called by both -controlTextDidChange: and your text field action. Your implementation of -controlTextDidChange: would have to grab the text field's formatter and attempt a string-to-number conversion, calling your core logic method with the results. But rather than doing that, Cocoa Bindings actually does what you want. (And the fact it usually—but not always!—uses KVO under the hood is probably why you've been getting away with KVO-observing your text fields.) Bind your text fields' Value binding to various NSNumber properties on your controller. Turn on Updates Value Continuously for all of these bindings. (I just confirmed that this works, unlike the isContinuous property on NSTextField itself.) Make sure your setters do the proper KVO-compliant updates for the other properties, either through +keyPathsForValuesAffecting… or by manual KVO notification. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
