Detailed Description

The QStyleOptionHeader class is used to describe the parameters for drawing a header. QStyleOptionHeader contains all the information that QStyle functions need to draw the item views' header pane, header sort arrow, and header label.

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 QStyleOptionHeader::StyleOptionType

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

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

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

enum QStyleOptionHeader::StyleOptionVersion

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

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

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.
