    The documentation says:

    The user is responsible for deleting the returned QOpcUaClient object when it is no longer needed.

    I'm not sure if I'm doing it the right way:

    QOpcUaClient *_opcUaClient;
    // ...
    
    // when I need to delete the client (i.e. after a disconnection)
    if (_opcUaClient)
    {
        _opcUaClient->disconnect();
        delete _opcUaClient;
        _opcUaClient = nullptr;
    }
    

    Is it correct?

      Hi,

      Signal/Slot disconnection should happen automatically upon deletion so there's no need to do that. Other than that, it looks good.
