详细描述

The QStyleOptionTab class is used to describe the parameters for drawing a tab bar.

The QStyleOptionTab class is used for drawing several built-in Qt widgets including QTabBar 和面板为 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 (),通常不需要校验它。

对于可以如何使用样式选项的演示范例,见 样式 范例。

enum QStyleOptionTab:: SelectedPosition

This enum describes the position of the selected tab. Some styles need to draw a tab differently depending on whether or not it is adjacent to the selected tab.

常量 描述

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

常量 描述
QStyleOptionTab::Type SO_Tab 提供样式选项的类型 ( SO_Tab 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.

enum QStyleOptionTab:: 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 描述

enum QStyleOptionTab:: TabFeature
flags QStyleOptionTab:: TabFeatures

Describes the various features that a tab button can have.
