enum QStyleOptionHeader::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.

Constant	Value	Description
`QStyleOptionHeader::Type`	`SO_Header`	The type of style option provided (SO_Header for this class).

See also: StyleOptionVersion

enum QStyleOptionHeader::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.

Constant	Value	Description
`QStyleOptionHeader::Version`	`1`	1
