+    \property QMenuBar::nativeMenuBar
+    \brief Whether or not a menubar will be used as a native menubar on platforms that support it
+    \since 4.6
+
+    This property specifies whether or not the menubar should be used as a native menubar on platforms
+    that support it. The currently supported platforms are Mac OS X and Windows CE. On these platforms
+    if this property is true, the menubar is used in the native menubar and is not in the window of
+    its parent, if false the menubar remains in the window. On other platforms the value of this
+    attribute has no effect.
+
+    The default is to follow whether the Qt::AA_DontUseNativeMenuBar attribute
+    is set for the application. Explicitly settings this property overrides
+    the presence (or abscence) of the attribute.
