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

      In the event that the writability change applies only to a single
      key, @key will be set to the #GQuark for that key. In the event
      that the writability change affects the entire settings object,
      @key will be 0.

      The default handler for this signal invokes the "writable-changed"
      and "changed" signals for each affected key. This is done because
      changes in writability might also imply changes in value (if for
      example, a new mandatory setting is introduced). If any other
      connected handler returns %TRUE then this default functionality
      will be suppressed.
      Parameter:
      key - the quark of the key, or 0
      Gibt zurück:
      %TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.
