QSignalMapper is /indeed/ the thing you're after: When setting it up (connecting the signals from the buttons to the QSignalMapper) it lets you assign unique/meaningful IDs to your buttons. So whenever the QSignalMapper fires its signal (because any button has been clicked) it provides this ID as signal parameter and hence in your slot (which is connected to the QSignalMapper signal) you know *which* button has been pressed :)


Cheers, Oliver
