详细描述

QStyleOptionTabBarBase contains all the information that QStyle functions need to draw the tab bar base. Note that this is only drawn for a standalone QTabBar (one that isn't part of a QTabWidget ).

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.

成员类型文档编制

enum QStyleOptionTabBarBase:: StyleOptionType

This enum is used to hold information about the type of the style option, and is defined for each QStyleOption 子类。

常量	值	描述
`QStyleOptionTabBarBase::Type`	`SO_TabBarBase`	提供样式选项的类型 ( SO_TabBarBase 对于此类)。

类型内部使用通过 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.

另请参阅 StyleOptionVersion .

enum QStyleOptionTabBarBase:: StyleOptionVersion

This enum is used to hold information about the version of the style option, and is defined for each QStyleOption 子类。

常量	值	描述
`QStyleOptionTabBarBase::Version`	`2`	2

版本的使用通过 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。
