Qt5: how to batch process by using QProcess

I want to let QProcess run many command at a time,instead of one at a time.

void Route::add_route()
{
    QProcess *Add_route = new QProcess(this);
    Add_route->start("notepad",QStringList() << "interface" << "ipv4" << "set" << "interface" << "" << "metric=1");
    Add_route->start("explorer",QStringList() << "interface" << "ipv6" << "set" << "interface" << "" << "metric=1");
    Add_route->waitForFinished();
}

By using this,it will only run the first one.
Ps: I'm using notepad and explorer just for test
Thanks!

QProcess as name suggest represents single process not multiple. So your requirement to run two processes using single QProcess object is faulty by design.

You have two choices:

QProcess has a member-function startDetached(). Use one QProcess for every process you need to start, not one QProcess for all processes. See http://doc.qt.io/qt-5/qprocess.html#startDetached
