+    parameters for drawing the frame around a tab widget.
+
+    QStyleOptionTabWidgetFrameV2 contains all the information that
+    QStyle functions need to draw the frame around QTabWidget.
+
+    For performance reasons, the access to the member variables is
+    direct (i.e., using the \c . or \c -> operator). This low-level feel
+    makes the structures straightforward to use and emphasizes that
+    these are simply parameters used by the style functions.
+
+    For an example demonstrating how style options can be used, see
+    the \l {widgets/styles}{Styles} example.
