ListHeader

open class ListHeader(pointer: <Error class: unknown class><<Error class: unknown class>>)

GtkListHeader is used by list widgets to represent the headers they display.

GtkListHeader objects are managed just like class@Gtk.ListItem objects via their factory, but provide a different set of properties suitable for managing the header instead of individual items.
