change_event
Description:
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.
Parameters:
| keys |
array of the keys which have changed |
| n_keys |
the length of the |
Returns:
|
true to stop other handlers from being invoked for the event, false to propagate the event further |
