ChartView RubberBand zoom out (right click) event

[cpper]

Hello,
I want to control the zoom out event caused by right clicking when rubber band is enabled in a chart view. I want to achieve this, but using eventFilter instead of subclassing QChartView. However, the mouse release event seems not to be triggered. Here is the code:

    //MainWindow constructor:
    chartView.setMouseTracking(true);
    chartView.setInteractive(true);
    
    chartView.installEventFilter(this);
 
  //..................

  bool MainWindow::eventFilter(QObject *watched, QEvent *event){ 
      if(watched == &chartView && event->type() == QEvent::MouseButtonRelease){
           if(static_cast<QMouseEvent*>(event)->button() == Qt::RightButton)  {
               qDebug() << "here i am" ;              
           }
       }
       return QMainWindow::eventFilter(watched, event);
  }

If I replace QEvent::MouseButtonRelease with QEvent::MouseButtonPress the event gets called. However the zooming out happens when releasing the mouse, so that is what I need to control.
