The "changed" signal is emitted when a key has potentially changed.
You should call one of the g_settings_get() calls to check the new
value.
This signal supports detailed connections. You can connect to the
detailed signal "changed::x" in order to only receive callbacks
when key "x" changes.
Note that @settings only emits this signal if you have read @key at
least once while a signal handler was already connected for @key.
