Detect out of coverage wit Qt

Hi

I have been testing QtNetwork for a while and I have used the onlineStateChanged(bool) signal from ConnectionManager. However this signal only seems to be emitted when we actually loose the network interface, for instance disabling the modem.

I wonder if there is a way to detect if we go out of coverage with Qt. For instance in Windows Mobile we instantly see a notification that we are out of coverage but this for sure is not reported by onlineStateChanged(bool).

Is there any other way?
