The QStyleOptionTabWidgetFrame class is used to describe the parameters for drawing the frame around a tab widget.
QStyleOptionTabWidgetFrame 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

or
->
operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
