MapListModelRef

public struct MapListModelRef : MapListModelProtocol, GWeakCapturing

A GtkMapListModel maps the items in a list model to different items.

GtkMapListModel uses a [callbackGtk.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 (G_TYPE_LIST_MODEL,
                                      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.

The MapListModelRef type acts as a lightweight Swift reference to an underlying GtkMapListModel instance. It exposes methods that can operate on this data type through MapListModelProtocol conformance. Use MapListModelRef only as an unowned reference to an existing GtkMapListModel instance.

  • ptr 
    Untyped pointer to the underlying `GtkMapListModel` instance.

    For type-safe access, use the generated, typed pointer map_list_model_ptr property instead.
