Answer 1

You have to Subclass most of the GUI classes, if you need to customize.

For NSTabView, this is one of the class where you have to do a lot of thing yourself.

You have to draw yourself ( using beziers path )

Need to implement many methods of NSView & NSResponder for drawing and event handling.
