Detailed Description

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 QNetworkSettingsType::type property, and network service items can be retrieved with the QNetworkSettingsServiceFilter::itemFromRow() method.

The following code demonstrates how you initialize the network manager:

manager = new QNetworkSettingsManager(this);
QObject::connect(manager, &QNetworkSettingsManager::interfacesChanged,
    this, &MainWindow::interfacesChanged);

QObject::connect(manager, &QNetworkSettingsManager::servicesChanged,
    this, &MainWindow::servicesChanged);

After initializing the network manager, you can iterate WiFi SSIDs as follows:

void WifiHandler::servicesChanged()
{
    QList<QNetworkSettingsService*> services = qobject_cast<QNetworkSettingsServiceModel*>(manager->services()->sourceModel())->getModel();

    for (const auto &service : services) {
        qDebug() << service->name();
    }
}


void WifiHandler::interfacesChanged()
{
    QList<QNetworkSettingsInterface*> interfaces = manager->interfaces()->getModel();
    for (const auto &interface : interfaces) {
        if (interface->type() == QNetworkSettingsType::Types::Wifi) {
            if (interface->powered()) {
                interface->scanServices();
            } else {
            interface->setPowered(true);
            }
        }
    }
}
