Detailed Description

The QStyleOptionHeader class is used to describe the parameters for drawing a header.

\inmodule QtWidgets

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, there are few member functions and the access to the member variables is direct (i.e., using the . or -> operator). This makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.

Member Enumeration Documentation

◆ SectionPosition

enum QStyleOptionHeader::SectionPosition

\variable QStyleOptionHeader::section

which section of the header is being painted

The default value is 0.

\variable QStyleOptionHeader::text

the text of the header

The default value is an empty string.

\variable QStyleOptionHeader::textAlignment

the alignment flags for the text of the header

The default value is Qt::AlignLeft.

\variable QStyleOptionHeader::icon

the icon of the header

The default value is an empty icon, i.e. an icon with neither a pixmap nor a filename.

\variable QStyleOptionHeader::iconAlignment

the alignment flags for the icon of the header

The default value is Qt::AlignLeft.

\variable QStyleOptionHeader::position

the section's position in relation to the other sections

The default value is QStyleOptionHeader::Beginning.

\variable QStyleOptionHeader::selectedPosition

the section's position in relation to the selected section

The default value is QStyleOptionHeader::NotAdjacent

\variable QStyleOptionHeader::sortIndicator

the direction the sort indicator should be drawn

The default value is QStyleOptionHeader::None.

This enum lets you know where the section's position is in relation to the other sections.

\value Beginning At the beginining of the header \value Middle In the middle of the header \value End At the end of the header \value OnlyOneSection Only one header section

◆ SelectedPosition

enum QStyleOptionHeader::SelectedPosition

This enum lets you know where the section's position is in relation to the selected section.

\value NotAdjacent Not adjacent to the selected section \value NextIsSelected The next section is selected \value PreviousIsSelected The previous section is selected \value NextAndPreviousAreSelected Both the next and previous section are selected

◆ SortIndicator

enum QStyleOptionHeader::SortIndicator

Indicates which direction the sort indicator should be drawn.

\value None No sort indicator is needed \value SortUp Draw an up indicator \value SortDown Draw a down indicator

SortUp
SortDown

◆ StyleOptionType

enum QStyleOptionHeader::StyleOptionType

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

\value Type The type of style option provided (\l{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.

Enumerator

Definition at line 170 of file qstyleoption.h.

◆ 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.

\value Version 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.
