    I launch a new process using QProcess:

    QProcess* pobjProc(new QProcess());
    pobjProc->start(strModule);
    if ( !pobjProc->waitForStarted() ) {
        delete pobjProc;
        return;
    }
    const Q_PID cpid(pobjProc->pid());
    mmpProcesses.insert(cpid, pobjProc);
    

    For testing I'm using gedit as the module to launch, the problem I'm seeing is that I want to be able to launch multiple instances and calling this again doesn't, it does re-focuses the already running instance of gedit.

    Do I need to add something to indicate new instance intended? This is using Qt 4.8

    [Edit] I've also tried the using startDetached same result, only one instance is launched.

    Kind Regards,
    Sy

      This is a behavior of your app you're starting - look for a command line argument to allow more than one instance of this application.

        @Christian-Ehrlicher , typical, I picked this application at random just to test and it does indeed have an argument --new-window to launch a new instance.

        Kind Regards,
        Sy
