How to stop a timer?

Hello!

I created the MainWindow project and added:

MainWindow.h

Code:

---

private:
    void timerEvent( QTimerEvent *event );

---

I wrote in the constructor of the MainWindow:

Code:

---

startTimer( 2000 );

---

I wrote:

Code:

---

void MainWindow::timerEvent(QTimerEvent *event)
{
    qDebug() << "timerEvent";
}

---

How to stop this timer here:

Code:

---

void MainWindow::on_startTransmissionButton_clicked()
{
 
}

---

P.S. I cannot find timerEvent in the Qt's documentation

QObject::killTimer

Thank you very much!

Code:

---

void MainWindow::on_startTransmissionButton_clicked()
{
    m_timerID = startTimer( 2000 );
}
 
void MainWindow::on_stopTransmissionButton_clicked()
{
    killTimer( m_timerID );
}

Added after 7 minutes:

It is better:

Code:

---

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    // ...
 
    ui->stopTransmissionButton->setEnabled( false );
}
 
// ...
 
void MainWindow::on_startTransmissionButton_clicked()
{
    m_timerID = startTimer( 2000 );
    ui->startTransmissionButton->setEnabled( false );
    ui->stopTransmissionButton->setEnabled( true );
}
 
void MainWindow::on_stopTransmissionButton_clicked()
{
    killTimer( m_timerID );
    ui->startTransmissionButton->setEnabled( true );
    ui->stopTransmissionButton->setEnabled( false );
}

Why muck with low level events and not simply use a QTimer?
