    \brief The QNetworkSettingsManager class manages network settings.

    The network manager is designed to be used as a model that contains lists
    of available network interfaces and services.

    A delegate in a view that uses the interface model can access the
    network interface item with the data model role.

    The services list in the model can be controlled with the
    \l QNetworkSettingsType::type property, and network service items can be
    retrieved with the \l QNetworkSettingsServiceFilter::itemFromRow() method.
