Connect to WritableChanged signal.

The "writable-changed" signal is emitted when the writability of a key has potentially changed. You should call [gio.settings.Settings.isWritable] in order to determine the new status.

This signal supports detailed connections. You can connect to the detailed signal "writable-changed::x" in order to only receive callbacks when the writability of "x" changes.

`detail`	Signal detail or null (default)
`callback`	signal callback delegate or function to connect `void callback(string key, gio.settings.Settings settings)` `key` the key (optional) `settings` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
