详细描述

QStyleOptionToolBox contains all the information that QStyle 函数需要绘制 QToolBox .

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.
