這段代碼...我不明白..能否解釋一下?越具體越好````復制代碼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(); }
