详细描述

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

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

出于性能原因,有很少成员函数,且对成员变量的访问是直接的 (即:使用 . or -> 运算符)。这使结构易于使用并强调这些只需通过样式函数使用参数。

对于可以如何使用样式选项的演示范例,见 样式 范例。
