\class QMacNativeWidget
\brief The QMacNativeWidget class provides a widget for Mac OS X that provides a way to put Qt widgets
into Cocoa hierarchies.
QMacNativeWidget bridges the gap between NSViews and QWidgets and makes it possible to put a
hierarchy of Qt widgets into a non-Qt window or view.
QMacNativeWidget pretends it is a window (i.e. isWindow() will return true),
but it cannot be shown on its own. It needs to be put into a window
when it is created or later through a native call.
Note that QMacNativeWidget requires knowledge of Cocoa. All it
does is get the Qt hierarchy into a window not owned by Qt. It is then up
to the programmer to ensure it is placed correctly in the window and
responds correctly to events.
