How to listen internet connection.

[William.Tran]

Hi All,

Do you know are there any way to trigger event network disable or enable?

I am doing like this:

networkConfigManager = new QNetworkConfigurationManager();

//for MAC
connect(networkConfigManager, SIGNAL(onlineStateChanged(bool)), this, SLOT(onlineStateChanged(bool)));

//for windows
connect(networkConfigManager,SIGNAL(configurationChanged(QNetworkConfiguration)), this, SLOT(networkConfigurationChanged()));

I don't know why "onlineStateChanged" not working on Windows. I have to use "configurationChanged" as you can see. However, it is not working as expected in case i have some virtual machine network. When i disable/enable internet the events were not fired.

Could someone help me on this?

Thank you!

@William.Tran
QNetworkAccessManager also has a networkAccessibleChanged() signal
Maybe this works out better for you.

Thank you for your supporting. However, i could not get networkAccessibleChanged signal working as expected. my script is below:

foreach(QNetworkConfiguration cfg, networkConfigManager->allConfigurations()){
//if(cfg.name() == "Ethernet 6"){
QNetworkAccessManager *accessManager = new QNetworkAccessManager();
accessManager->setConfiguration(cfg);
qDebug() << cfg.name() << accessManager->networkAccessible();
connect(accessManager, SIGNAL(networkAccessibleChanged(QNetworkAccessManager::NetworkAccessibility)), this, SLOT(networkAccessibleChanged(QNetworkAccessManager::NetworkAccessibility)));
//}
}
