这段代码...我不明白..能否解释一下?
越具体越好````

QNetworkConfigurationManager manager;
if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
// Get saved network configuration
//QMessageBox::information(NULL,tr("test"),tr("what happen!"));
QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
settings.beginGroup(QLatin1String("QtNetwork"));
const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
settings.endGroup();
// If the saved network configuration is not currently discovered use the system default
QNetworkConfiguration config = manager.configurationFromIdentifier(id);
if ((config.state() & QNetworkConfiguration::Discovered) !=
QNetworkConfiguration::Discovered) {
config = manager.defaultConfiguration();
}
networkSession = new QNetworkSession(config, this);
connect(networkSession, SIGNAL(opened()), this, SLOT(sessionOpened()));
getFortuneButton->setEnabled(false);
statusLabel->setText(tr("Opening network session."));
networkSession->open();
}
