1. listHeaderGetChild :: (HasCallStack, MonadIO m, IsListHeader a) => a -> m (Maybe Widget)

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Gets the child previously set via listHeaderSetChild or Nothing if none was set. Since: 4.12

2. listHeaderGetEnd :: (HasCallStack, MonadIO m, IsListHeader a) => a -> m Word32

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Gets the end position in the model of the section that self is currently the header for. If self is unbound, INVALID_LIST_POSITION is returned. Since: 4.12

3. listHeaderGetItem :: (HasCallStack, MonadIO m, IsListHeader a) => a -> m (Maybe Object)

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Gets the model item at the start of the section. This is the item that occupies the list model at position ListHeader:start. If self is unbound, this function returns Nothing. Since: 4.12

4. listHeaderGetNItems :: (HasCallStack, MonadIO m, IsListHeader a) => a -> m Word32

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Gets the the number of items in the section. If self is unbound, 0 is returned. Since: 4.12

5. listHeaderGetStart :: (HasCallStack, MonadIO m, IsListHeader a) => a -> m Word32

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Gets the start position in the model of the section that self is currently the header for. If self is unbound, INVALID_LIST_POSITION is returned. Since: 4.12

6. listHeaderSetChild :: (HasCallStack, MonadIO m, IsListHeader a, IsWidget b) => a -> Maybe b -> m ()

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Sets the child to be used for this listitem. This function is typically called by applications when setting up a header so that the widget can be reused when binding it multiple times. Since: 4.12

7. setListHeaderChild :: (MonadIO m, IsListHeader o, IsWidget a) => o -> a -> m ()

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Set the value of the “child” property. When overloading is enabled, this is equivalent to

   set listHeader [ #child := value ]
   

8. toListHeader :: (MonadIO m, IsListHeader o) => o -> m ListHeader

   gi-gtk4	GI.Gtk.Objects.ListHeader

   Cast to ListHeader, for types for which this is known to be safe. For general casts, use castTo.

9. clearListViewHeaderFactory :: (MonadIO m, IsListView o) => o -> m ()

   gi-gtk4	GI.Gtk.Objects.ListView

   Set the value of the “header-factory” property to Nothing. When overloading is enabled, this is equivalent to

   clear #headerFactory
   

10. constructListViewHeaderFactory :: (IsListView o, MonadIO m, IsListItemFactory a) => a -> m (GValueConstruct o)

    gi-gtk4	GI.Gtk.Objects.ListView

    Construct a GValueConstruct with valid value for the “header-factory” property. This is rarely needed directly, but it is used by new.
