QProcess 怎么读取控制台输出

Question

我写了一个helloworld，希望通过QProcess运行，并且读取输出，但是怎样都读取不到
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

    QString my_process_2 = "C:/Users/lin/Desktop/qt_1/t1.exe";

    process = new QProcess();
    qDebug()<<my_process_2;
    QStringList argument;

    process->start(my_process_2);
    if (!process->waitForStarted())
    {
        qDebug() << "启动失败";

    }

    connect(process,SIGNAL(readyRead()),this,SLOT(Fctn_get_info()));

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::Fctn_get_info()
{
qDebug()<<"start";
QString s = tr("");
s+= process->readAll();
qDebug()<<s;
return;
}
求大神解答

Signals：
void readyReadStandardOutput()
QByteArray QProcess::readAllStandardOutput()
Regardless of the current read channel, this function returns all data available from the standard output of the process as a QByteArray.

你可以用这个信号，readyReadStandardOutput()
