I'm working through Aaron Hillegass' "Cocoa Programming For Mac OS X (3rd Ed)" and I'm near the end of chapter 9 (pg 148) where it is shown to make use of the changeKeyPath method. I'm in the habit of right clicking on method names and choosing "Find selected text in API reference/in documenation". When I do this for "changeKeyPath", nothing comes up on my machine?
This is because changeKeyPath:ofObject:toValue is new method in the application. It is a little confusing. The implementation of the Cocoa method observeValueForKeyPath:ofObject:change:context registers the call to changeKeyPath:ofObject:toValue to be called later if an undo occurs.
It is all a bit confusing since the book shows the implementation of the changeKeyPath:ofObject:toValue: before it shows how it will get
called. Read about this in the Undo Architecture documentation. mkd _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
