How to detect a process ?

Hello,

I made a small application, but I must be sure that the user won't launch it 2 time at once.
So, I would like to detect if a process called "toto.exe" is running, but I didn't find how to do that.

I had a look to QProcess, but it seems that we can only find parent or child process with this class.

Have you got an idea ?:)
