public void add_action (Action action)
Adds an action object to the action group.
Note that this function does not set up the accel path of the action, which can lead to problems if a user tries to modify the accelerator of a menuitem associated with the action. Therefore you must either set the accel path yourself with set_accel_path, or use `gtk_action_group_add_action_with_accel (..., NULL)`.
