QProcess has nothing to do with this, I'm not an expert in this, but
usually child processes are killed along with their parent process if the
parent dies. So I'm guessing the spawned process you see is actually not a
child anymore because it makes sure to get a child of the init process.
Thats usually done for daemon applications and those either have a way of
running <yourdaemonapp> --kill or you'll have to work with platform
specific API's to find out the process id of the process and then send it a
TERM/KILL signal (or the equivalent on non-unix platforms)
