Struct qt_widgets::QStyleOptionHeader

#[repr(C)]pub struct QStyleOptionHeader { /* fields omitted */ }

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

C++ class: QStyleOptionHeader.

C++ documentation:

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.

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