QProcess *process = new QProcess(this);
QString file("D:\\Python_practice\\proto4\\Surface Evolver Code\\F_Passive_for_UI.fe");
process->execute(file);
//process->start(file);
QDesktopServices::openUrl(QUrl("file:///"+file,QUrl::TolerantMode));
}

From QProcess doc : QProcess allows you to treat a process as a sequential I/O device. You can write to and read from the process just as you would access a network connection using QTcpSocket. You can then write to the process's standard input by calling write(), and read the standard output by calling read(), readLine(), and getChar().
