Starting with Quicktime X and now with Facetime, Apple has introduced a new black ui titlebar. There's no NS component at the moment or any flag of NSWindow, so I've decided to throw away ten minutes to write my own black titlebar.BlackWindow.h/BlackWindow.m) that initializes a window without borders (styleMask NSBorderlessWindowMask) and I've created a NSView that draws the titlebar (BlackWindowTitleView.h/BlackWindowTitleView.m).
The titlebar redraws itself when some changes are applied to the window. With key value observing for title, document edited, ... and NSNotificationCenter for KeyNotifications the titlebar knows what to do.
Source code can be found on my GitHub under blog-code/MacBlackWindow.
