-                                        instead it will be mapped to the corresponding QScreen's QScreen::primaryOrientation().
+    \value PrimaryOrientation           The display's primary orientation.
     \value LandscapeOrientation         Landscape orientation, display width is greater than display height.
     \value PortraitOrientation          Portrait orientation, display height is greater than display width,
                                         rotated 90 degree clockwise relative to landscape.
