QScroller does not work in QScrollArea in QDialog? ( It works fine in a QScrollArea under QMainWindow )

[EdOfTheMountain]

I have been struggling with this for days. QScroller works fine on Android for QScrollAreas and QTableWidgets contained in a QMainWindow.

Why would it not work on a QScrollArea contained in a QDialog? Modal or not it does not work.

Thanks for any ideas,

/// This works fine for both QScrollAreas and QTableWidgets contained in a QStackedWidget under a QMainWindow
/// The same code operating on a QScrollArea contained in a QDialog does not work?
/// modal or not-modal does not work?
void FormApplicationSettings::setupKineticScrolling(QScrollArea *scrollArea)
{
QScroller::grabGesture(scrollArea->viewport(),
QScroller::LeftMouseButtonGesture);

// Adjust OvershootPolicy so it does not look wobbly, like table not attached to widget
QScrollerProperties properties = QScroller::scroller(scrollArea)->scrollerProperties();
QVariant overshootPolicy =
        QVariant::fromValue<QScrollerProperties::OvershootPolicy>
        (QScrollerProperties::OvershootAlwaysOff);
properties.setScrollMetric(QScrollerProperties::HorizontalOvershootPolicy,
                           overshootPolicy);
properties.setScrollMetric(QScrollerProperties::VerticalOvershootPolicy,
                           overshootPolicy);
QScroller::scroller(scrollArea)->setScrollerProperties(properties);
