Memory-managed wrapper type.

A convenience alias for Nothing :: Maybe ActionMap.

Type class for types which can be safely cast to ActionMap, for instance with toActionMap.

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

Adds an action to the actionMap.

If the action map already contains an action with the same name as action then the old action is dropped from the action map.

The action map takes its own reference on action.

A convenience function for creating multiple SimpleAction instances and adding them to a ActionMap.

Each action is constructed as per one ActionEntry.

C code

static void
activate_quit (GSimpleAction *simple,
               GVariant      *parameter,
               gpointer       user_data)
{
  exit (0);
}

static void
activate_print_string (GSimpleAction *simple,
                       GVariant      *parameter,
                       gpointer       user_data)
{
  g_print ("%s\n", g_variant_get_string (parameter, NULL));
}

static GActionGroup *
create_action_group (void)
{
  const GActionEntry entries[] = {
    { "quit",         activate_quit              },
    { "print-string", activate_print_string, "s" }
  };
  GSimpleActionGroup *group;

  group = g_simple_action_group_new ();
  g_action_map_add_action_entries (G_ACTION_MAP (group), entries, G_N_ELEMENTS (entries), NULL);

  return G_ACTION_GROUP (group);
}

Looks up the action with the name actionName in actionMap.

If no such action exists, returns Nothing.

Since: 2.32

Removes the named action from the action map.

If no action of this name is in the map then nothing happens.
