QStyleOptionTab 类用于绘制几种内置 Qt Widget 包括 QTabBar 和面板为 QTabWidget .
QStyleOptionTab 类实例拥有 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 ()，通常不需要校验它。
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。
