The API changed a bit after modemmanager-qt became a KDE framework.

Unfortunately there is no example for that particular case, but if you go 
through plasma-nm, there's a lot of stuff using networkmanager-qt/

signal/slot mechanism.

You can also send us your code so we can take a look and help you more with 
that.
