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 [signal@Gio.Settings:GSettings:changed] signal. For most use cases it is more appropriate to use the [
signal@Gio.Settings:GSettings:changed] signal.
In the event that the change event applies to one or more specified keys, keys will be an array of [alias@GLib.Quark]s of
length keys.length. In the event that the change event applies to the [class@Gio.Settings] object as a whole (ie: potentially
every key has been changed) then keys will be `NULL` and keys.length will be `0`.
The default handler for this signal invokes the [signal@Gio.Settings:GSettings:changed] signal for each affected key. If any
other connected handler returns true then this default functionality will be suppressed.
