Signal ID
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.
