Connect to GPropertiesChanged signal.

Emitted when one or more D-Bus properties on proxy changes. The local cache has already been updated when this signal fires. Note that both changed_properties and invalidated_properties are guaranteed to never be null (either may be empty though).

If the proxy has the flag [gio.types.DBusProxyFlags.GetInvalidatedProperties] set, then invalidated_properties will always be empty.

This signal corresponds to the PropertiesChanged D-Bus signal on the org.freedesktop.DBus.Properties interface.

Parameters

after Yes.After to execute callback after default handler, No.After to execute before (default)
