The QStyleOptionTab class is used for drawing several built-in Qt widgets including QTabBar and the panel for QTabWidget. Note that to describe the parameters necessary for drawing a frame in Qt 4.1 or above, you must use the QStyleOptionFrameV2 subclass.

An instance of the QStyleOptiontabV2 class has type SO_Tab and version 1. The type is used internally by QStyleOption, its subclasses, and 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 subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally do not need to check it.

If you create your own QStyle subclass, you should handle both QStyleOptionTab and QStyleOptionTabV2.

For an example demonstrating how style options can be used, see the Styles example.

Type Documentation

QStyleOptionTab.CornerWidget

These flags indicate the corner widgets in a tab.

The CornerWidgets type is a typedef for QFlags<CornerWidget>. It stores an OR combination of CornerWidget values.

See also cornerWidgets.

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.

See also selectedPosition.

QStyleOptionTab.StyleOptionType

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

The type is used internally by QStyleOption, its subclasses, and 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.

See also StyleOptionVersion.

QStyleOptionTab.StyleOptionVersion

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

The version is used by QStyleOption subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast(), you normally do not need to check it.

See also StyleOptionType.

QStyleOptionTab.TabPosition

This enum describes the position of the tab.

See also position.

Method Documentation

QStyleOptionTab.__init__ (self)
