詳細描述

QStyleOptionButton contains all the information that QStyle functions need the various graphical elements of a group box.

它保持 lineWidth 和 midLineWidth for drawing the panel, the group box's title and the title's alignment and color .

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.
