Yes. The agent's constructor sets up the watcher and afterwards calls the slot reponsable for registering the agent. If NM is running the registration succeeds and that is it. If NM is not running the registration fails, but whenever NM appears on the system bus the slot is called again and it registers the agent. This scheme also works when NM restarts. If you call the registration slot only on knetworkmanager start the agent will stop working when NM restarts.

You are welcome.
