The QStyleOptionFrameV3 class is used to describe the parameters necessary for drawing a frame in Qt 4.1 or above.
QStyleOptionFrameV3 继承 QStyleOptionFrameV2
An instance of the QStyleOptionFrameV3 class has type SO_Frame and version 3. 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。
