KVO Bindings Project

People

Student: Christopher Farber

Mentor: Nicola Pero

Overview

KVO and bindings lead to faster, easier application development, and cleaner code. It also brings GNUstep closer to compiling most Cocoa code without modification. Key Value Observing is necessary to implement bindings, and would increase the flexibility of GNUstep's KeyValueCoding implementation. Bindings support would eliminate the need for most outlets and controller code that deals with updating the GUI controls, while reinforcing the separation between Controller and View in the Model-View-Controller design pattern.

Deliverables

Creating the classes:

• NSController
• NSArrayController
• NSObjectController
• NSValueTransformer

Adding bindings support for existing classes; for example NSTextField, NSPopUpButton, and NSProgressIndicator
