Class
Gtk.MapListModel
Description [src]
final class Gtk.MapListModel : GObject.Object {
/* No available fields */
}A GtkMapListModel maps the items in a list model to different items.
GtkMapListModel uses a [callback@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 (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.
