              grabGesture(Qt::PinchGesture);
          }
          bool event(QEvent* event) {
              if (event->type() == QEvent::Gesture) {
                  QGestureEvent *gesture = static_cast<QGestureEvent*>(event);
                  if (QPinchGesture *pinch = static_cast<QPinchGesture *>(
                              gesture->gesture(Qt::PinchGesture))) {
                      qDebug() << "Pinch";
                  }
                  if (QPanGesture *pan = static_cast<QPanGesture *>(
                              gesture->gesture(Qt::PanGesture))) {
                      qDebug() << "Pan";
                   }
              }
