The "changed" signal is emitted when a key has potentially changed.
You should call one of the @get calls to check the new value.
This signal supports detailed connections. You can connect to the detailed signal "changed:GSettings: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.
