How to stop a timer?

[8Observer8]

Hello!

I created the MainWindow project and added:

MainWindow.h

private:
    void timerEvent( QTimerEvent *event );

private:
    void timerEvent( QTimerEvent *event );

To copy to clipboard, switch view to plain text mode 

I wrote in the constructor of the MainWindow:

startTimer( 2000 );

startTimer( 2000 );

To copy to clipboard, switch view to plain text mode 

I wrote:

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

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

To copy to clipboard, switch view to plain text mode 

How to stop this timer here:

void MainWindow::on_startTransmissionButton_clicked()
{
 
}

void MainWindow::on_startTransmissionButton_clicked()
{

}

To copy to clipboard, switch view to plain text mode 

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