詳細描述

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.

enum QStyleOptionTabBarBase:: StyleOptionType

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

常量	值	描述
`QStyleOptionTabBarBase::Type`	`SO_TabBarBase`	提供樣式選項的類型 ( SO_TabBarBase 對於此類)。

類型內部使用通過 QStyleOption ，其子類，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.

enum QStyleOptionTabBarBase:: StyleOptionVersion

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

常量	值	描述

版本的使用通過 QStyleOption 子類以實現擴展在不破壞兼容性的情況下。若使用 qstyleoption_cast ()，通常不需要校驗它。
