详细描述

The QStyleOptionTabWidgetFrameV2 class is used to describe the 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 . or -> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.
