Settings.connectChanged

Connect to Changed signal.

The "changed" signal is emitted when a key has potentially changed. You should call one of the gio.settings.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.
