// QCocoaWindow
//
// QCocoaWindow is an NSView (not an NSWindow!) in the sense
// that it relies on a NSView for all event handling and
// graphics output and does not require a NSWindow, except for
// for the window-related functions like setWindowTitle.
//
// As a consequence of this it is possible to embed the QCocoaWindow
// in an NSView hierarchy by getting a pointer to the "backing"
// NSView and not calling QCocoaWindow::show():
//
// QWindow *qtWindow = new MyWindow();
// qtWindow->create();
// QPlatformNativeInterface *platformNativeInterface = QGuiApplication::platformNativeInterface();
// NSView *qtView = (NSView *)platformNativeInterface->nativeResourceForWindow("nsview", qtWindow);
// [parentView addSubview:qtView];
//
// See the qt_on_cocoa manual tests for a working example, located
// in tests/manual/cocoa at the time of writing.
