1. type MapListModelMapFunc = Object -> IO Object

   gi-gtk4	GI.Gtk.Callbacks

   User function that is called to map an item of the original model to an item expected by the map model. The returned items must conform to the item type of the model they are used with.

2. type MapListModelMapFunc_WithClosures = Object -> Ptr () -> IO Object

   gi-gtk4	GI.Gtk.Callbacks

   User function that is called to map an item of the original model to an item expected by the map model. The returned items must conform to the item type of the model they are used with.

3. module GI.Gtk.Objects.MapListModel

   A GtkMapListModel maps the items in a list model to different items. GtkMapListModel uses a [callbackgtk.MapListModelMapFunc]. Example: Create a list of GtkEventControllers

   c code

   static gpointer
   map_to_controllers (gpointer widget,
   gpointer data)
   {
   gpointer result = gtk_widget_observe_controllers (widget);
   g_object_unref (widget);
   return result;
   }
   
   widgets = gtk_widget_observe_children (widget);
   
   controllers = gtk_map_list_model_new (widgets,
   map_to_controllers,
   NULL, NULL);
   
   model = gtk_flatten_list_model_new (GTK_TYPE_EVENT_CONTROLLER,
   controllers);
   

   GtkMapListModel will attempt to discard the mapped objects as soon as they are no longer needed and recreate them if necessary. GtkMapListModel passes through sections from the underlying model.

4. newtype MapListModel

   gi-gtk4	GI.Gtk.Objects.MapListModel

   Memory-managed wrapper type.

5. MapListModel :: ManagedPtr MapListModel -> MapListModel

   gi-gtk4	GI.Gtk.Objects.MapListModel

   No documentation available.

6. module GI.HarfBuzz.Structs.MapT

   Data type for holding integer-to-integer hash maps.

7. newtype MapT

   gi-harfbuzz	GI.HarfBuzz.Structs.MapT

   Memory-managed wrapper type.

8. MapT :: ManagedPtr MapT -> MapT

   gi-harfbuzz	GI.HarfBuzz.Structs.MapT

   No documentation available.

9. class Map0_10 (ss :: [(k0, k1, k2, k3, k4, k5, k6, k7, k8, k9)])

   hetero-parameter-list-with-typelevel-tools	Data.HeteroParList.Tuple

   No documentation available.

10. class Map0_2 (ss :: [(k0, k1)])

    hetero-parameter-list-with-typelevel-tools	Data.HeteroParList.Tuple
