      boolean onChangeEvent(@Nullable Pointer keys, int n_keys)
      The "change-event" signal is emitted once per change event that
      affects this settings object. You should connect to this signal
      only if you are interested in viewing groups of changes before they
      are split out into multiple emissions of the "changed" signal.
      For most use cases it is more appropriate to use the "changed" signal.

      In the event that the change event applies to one or more specified
      keys, @keys will be an array of #GQuark of length @n_keys. In the
      event that the change event applies to the #GSettings object as a
      whole (ie: potentially every key has been changed) then @keys will
      be %NULL and @n_keys will be 0.

      The default handler for this signal invokes the "changed" signal
      for each affected key. If any other connected handler returns
      %TRUE then this default functionality will be suppressed.
      Parameter:
      keys - an array of #GQuarks for the changed keys, or %NULL
      n_keys - the length of the @keys array, or 0
      Gibt zurück:
      %TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.
