When I try something just like you did I get "QProcess: Destroyed while process is still running"... but with static functions it works... I'm running this on Linux, may be that's the problem, I don't know... I've created a test slot that just prints a string, and it works, so this isn't a problem of calling a non-static member function...

For now I can do with the static ones, we'll see how it goes with other classes...

Thanks again for everything!
