Detecting network type is 3G or Wifi

[lyhoanghai]

Hello,

I would like my application to behave differently for Wifi and 3G network.
The problem is that my application has to detect which network that QNetworkAccessManager is using.

For Qt 4.7, QNetworkAccessManager has a method called configuration() which returned the configuration used for creating connection.
If I want to do the same thing for Qt4.6, how do I do that? (4.6 does not have configuration method).

Any idea aboyt this?

Thank

Hai

If Qt-4.7 already has this:
http://qt.gitorious.org/qt

You can look at the code of QNetworkAccessManager.

Thanks for your link.
A quick look to QNetworkAccessManager.createRequest() shows that

if (!d->networkSession && (d->initializeSession || !d->networkConfiguration.isEmpty())) {
 
966 	
 
        QNetworkConfigurationManager manager;
 
967 	
 
        if (!d->networkConfiguration.isEmpty()) {
 
968 	
 
            d->createSession(manager.configurationFromIdentifier(d->networkConfiguration));
 
969 	
 
        } else {
 
970 	
 
            if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired)
 
971 	
 
                d->createSession(manager.defaultConfiguration());
 
972 	
 
            else
 
973 	
 
                d->initializeSession = false;
 
974 	
 
        }
 
975 	
 
    }

if (!d->networkSession && (d->initializeSession || !d->networkConfiguration.isEmpty())) {

966 	

        QNetworkConfigurationManager manager;

967 	

        if (!d->networkConfiguration.isEmpty()) {

968 	

            d->createSession(manager.configurationFromIdentifier(d->networkConfiguration));

969 	

        } else {

970 	

            if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired)

971 	

                d->createSession(manager.defaultConfiguration());

972 	

            else

973 	

                d->initializeSession = false;

974 	

        }

975 	

    }

Thus, QNetworkAccessManager use NetworkConfigurationManager.defaultConfiguration() .
