QStyleOptionTab class is used to describe the parameters for drawing a tab bar.
QStyleOptionTab class is used for drawing several built-in Qt widgets including QTabBar and the panel for QTabWidget .
An instance of the QStyleOptionTab class has type SO_Tab 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 (), you normally do not need to check it.
