@Generated("io.github.jwharm.JavaGI") public class MapListModel<T extends GObject> extends GObject implements ListModel<T>, SectionModel<T>
A list model that maps the items in another model to different items.

GtkMapListModel uses a Gtk.MapListModelMapFunc.

Example: Create a list of GtkEventControllers 

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.
