在類的成員函式中寫：

QFuture<void> future = QtConcurrent::run(runVipNet,this
 
,path);

//阻塞主執行緒直到計算完成

future.waitForFinished();

runVipNet是類外函式：

//

void runVipNet(QMainWindow *receiver,QString _path)

{

    QApplication::postEvent(receiver,new ProgressEvent(true, (DWORD)QThread::currentThreadId()));

    MainWindow* s = (MainWindow*) receiver;

    
 
//獲取執行緒ID

    s->addThreadID((DWORD)QThread::currentThreadId());

    //執行外部exe

    QProcess::startDetached(_path,QStringList());

}

//

bool MainWindow::event(QEvent *event)

{

    if (event->type() == static_cast<QEvent::Type>(ProgressEvent::EventId))

    {

         ProgressEvent *progressEvent = static_cast<ProgressEvent*>(event);

         Q_ASSERT(progressEvent);

         ui->textBrowser->append(QString::number(progressEvent->message));

         return true;

    }

    return QMainWindow::event(event);

}
