</span>The API changed a bit after modemmanager-qt became a KDE framework.<br>

</span>Unfortunately there is no example for that particular case, but if you go<br>
through plasma-nm, there's a lot of stuff using networkmanager-qt/<br>
modemmanager-qt code (check src/libs/models/networkmodel.cpp).<br>

<br>
</span>I think you need to derive your class from QObject to be able to use Qt's<br>
signal/slot mechanism.<br>
<br>
You can also send us your code so we can take a look and help you more with<br>
that.<br>
