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.
This enum lets you know where the section's position is in relation to the other sections.
Constant | Value | Description |
---|---|---|
QStyleOptionHeader::Beginning | 0 | At the beginning of the header |
QStyleOptionHeader::Middle | 1 | In the middle of the header |
QStyleOptionHeader::End | 2 | At the end of the header |
QStyleOptionHeader::OnlyOneSection | 3 | Only one header section |
This enum lets you know where the section's position is in relation to the selected section.
Constant | Value | Description |
---|---|---|
QStyleOptionHeader::NotAdjacent | 0 | Not adjacent to the selected section |
QStyleOptionHeader::NextIsSelected | 1 | The next section is selected |
QStyleOptionHeader::PreviousIsSelected | 2 | The previous section is selected |
QStyleOptionHeader::NextAndPreviousAreSelected | 3 | Both the next and previous section are selected |
Indicates which direction the sort indicator should be drawn
Constant | Value | Description |
---|---|---|
QStyleOptionHeader::None | 0 | No sort indicator is needed |
QStyleOptionHeader::SortUp | 1 | Draw an up indicator |
QStyleOptionHeader::SortDown | 2 | Draw a down indicator |
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.
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.
QStyleOptionHeader::QStyleOptionHeader | ( | ) |
Constructs an empty QStyleOptionHeader.
|
inline |
Copy constructs a new QStyleOptionHeader from other.
|
default |
Copy assigns from other and returns a reference to this object.
