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.
