Swipe gesture not recognized

[Luc4]

Hi! I'm trying to enable a swipe gesture. I created a test class like this following the documentation and the example:

GestureLabel::GestureLabel(QWidget *parent) :
      QWidget(parent)
{
   grabGesture(Qt::SwipeGesture);
}
 
bool GestureLabel::event(QEvent *e)
{
   if (e->type() == QEvent::Gesture)
      return gestureEvent(static_cast<QGestureEvent*>(e));
   return QWidget::event(e);
}
 
bool GestureLabel::gestureEvent(QGestureEvent *event)
{
   if (QGesture *swipe = event->gesture(Qt::SwipeGesture))
      swipeTriggered(static_cast<QSwipeGesture *>(swipe));
   return true;
}
 
void GestureLabel::swipeTriggered(QSwipeGesture *gesture)
{
   QMessageBox::information(this, "Gesture!", "Gesture!");
}

GestureLabel::GestureLabel(QWidget *parent) :
      QWidget(parent)
{
   grabGesture(Qt::SwipeGesture);
}

bool GestureLabel::event(QEvent *e)
{
   if (e->type() == QEvent::Gesture)
      return gestureEvent(static_cast<QGestureEvent*>(e));
   return QWidget::event(e);
}

bool GestureLabel::gestureEvent(QGestureEvent *event)
{
   if (QGesture *swipe = event->gesture(Qt::SwipeGesture))
      swipeTriggered(static_cast<QSwipeGesture *>(swipe));
   return true;
}

void GestureLabel::swipeTriggered(QSwipeGesture *gesture)
{
   QMessageBox::information(this, "Gesture!", "Gesture!");
}

To copy to clipboard, switch view to plain text mode 

Seems not to recognize swipes. I tried to put a breakpoint in line:

return gestureEvent(static_cast<QGestureEvent*>(e));

return gestureEvent(static_cast<QGestureEvent*>(e));

To copy to clipboard, switch view to plain text mode 

and seems the execution doesn't stop there. Is there anything I'm doing wrong? Am I lacking anything?
Thanks for any advice!

did you find solution?
