nstabview

As discussed elsewhere, NSTabView does not have a setBackgroundColor method and subclassing NSTabView and using an drawRect to control it does no longer work - as it does not paint the top 10%, the bit just below the segmented control button. Now I am a bit surprised by the amounts of work arounds I had to do solving this; see code: https://github.com/dirkx/CustomizableTabView/blob/master/CustomizableTabView/CustomizableTabView.m and am wondering if i went down the wrong path. And how to do this better & simpler: The NSSegmentStyleTexturedSquare seems to yield me a semi-transparent segmented

Various Preferences dialogs (Safari, Mail, Xcode4, and any that uses NSPreferences) and Xcode4's Organizer use something reminiscent of a tab view -- except that is uses toolbar buttons for switching between tabs. These buttons are "pressed". What is the best way to implement such a tab view? Is there a documented public API for implementing them? Since Mac OS X 10.10 (Yosemite), the easiest way to do this is to lay out your preferences dialog window in a storyboard using an NSTabViewController , and set its tabStyle to NSTabViewControllerTabStyleToolbar .
