Infinity Loop does not end when program is closed - c++

Question

I have an infinity loop whithin the run-method of my QThread subclass. This thread should exist till the application is closed. The Code looks something like this.
loopThread.h:
class loopThread : public QThread
{
Q_OBJECT
public:
loopThread();
~loopThread();
protected:
void run() override;
signals:
void resultReady();
};
The implementation of the subclass is as follows:
loopThread.cpp:
void loopThread::run()
{ while(!this->isInterruptionRequested()){
std::cout << "loop active" << std::endl; //checking if it executes the loop or not
}
}
the run()-method executes a infinity loop until requesInterruption() is called in the mainWindow class.
MainWindow.h:
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(QWidget *parent = nullptr);
~MainWindow();
void closeEvent(QCloseEvent *event);
private:
Ui::MainWindow *ui;
loopThread *loopThread = nullptr;
public slots:
void handleResult();
};
The Implementation for this class says
MainWindow.cpp:
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
, ui(new Ui::MainWindow)
{
ui->setupUi(this);
loopThread = new loopThread();
connect(loopThread, &loopThread::noButtonClicked, this, &loopThread::NoButton);
connect(loopThread, &loopThread::finished, loopThread, &loopThread::deleteLater);
loopThread->start();
}
MainWindow::~MainWindow()
{
loopThread->quit();
loopThread->wait();
delete ui;
}
void MainWindow::closeEvent(QCloseEvent *event)
{
loopThread->requestInterruption();
}
So I would suggest that when I close the application by clicking in the "X" in the window the loop should end and the program should stop. The problem is even after closing the window the Console gives me the message "loop active" so it the loop still goes on. Where's my mistake. Is there a way to let a loop end when the program is closed?
The solution with moving a QObject to a Thread produces the same problem.

Thanks for the help guys!
I managed to solve this problem. AS said the infinite loop in the run()-method just send the message to the console. I have avoided this by just let the loop run without any task.
in my case i needed to check the serialcommunication so with the signal readyRead() i can now read this serial message. The loop is therfore executed until i stop the app. hopefulle that doesnt confuse too much. I will post my code when i have time.
