详细描述

The QStyleOptionToolBoxV2 class is used to describe the parameters necessary for drawing a frame in Qt 4.3 or above.

QStyleOptionToolBoxV2 继承 QStyleOptionToolBox which is used for drawing the tabs in a QToolBox .

An instance of the QStyleOptionToolBoxV2 class has type SO_ToolBox and version 2. The type is used internally by QStyleOption ，其子类，和 qstyleoption_cast () to determine the type of style option. In general you do not need to worry about this unless you want to create your own QStyleOption subclass and your own styles. The version is used by QStyleOption 子类以实现扩展在不破坏兼容性的情况下。若使用 qstyleoption_cast ()，通常不需要校验它。

If you create your own QStyle subclass, you should handle both QStyleOptionToolBox and QStyleOptionToolBoxV2 .
