gtk:column-view-header-factory (object)

object -- a gtk:column-view object
factory -- a gtk:list-item-factory object to use

Accessor of the header-factory slot of the gtk:column-view class. The gtk:column-view-header-factory function gets the factory that is currently used to populate section headers. The (setf gtk:column-view-header-factory) function sets the gtk:list-item-factory object to use for populating the gtk:list-header objects used in section headers. If this factory is set to nil, the list will not show section headers.
