Check network connection

[sophister]

Hello:
I want to write a application that can record the time my computer's network connection is activited (i.e, I can surf the Internet with it) and the time it becomes disconnected.

I use the QNetworkAccessManager::get(QNetworkRequest&) to test the network connection. But the question is, I am thinking that it is not the best way or right way to test network connection using that method.

Can you give me some advice?
Thanks a lot!
