QGestures on Symbian^3 (Qt 4.7.3)

[gardiol]

Ok guys, i am getting mad here. I am trying to enable pinch zoom in my app but with no luck whatsoever. What i am doing wrong?

class PreviewWidget : public QWidget
{
Q_OBJECT
public:
    PreviewWidget(QWidget *parent = 0);

protected:
    void paintEvent(QPaintEvent *);
    void resizeEvent(QResizeEvent *);
    void mousePressEvent(QMouseEvent *);
    void mouseMoveEvent(QMouseEvent *);
    void mouseReleaseEvent(QMouseEvent *);

    void pinchGesture(QPinchGesture *);

    bool event(QEvent *event);
    bool gestureEvent(QGestureEvent *event);

private:
    QPixmap image;
    QPointF _viewOffset;
    qreal _zoomFactor;
    bool isDragging;

};

And:

PreviewWidget::PreviewWidget(QWidget *parent) :
    QWidget(parent)
{
    grabGesture(Qt::PinchGesture);
    isDragging = false;
}

void PreviewWidget::resizeEvent(QResizeEvent * re)
{
    calculateZoom(re->size());
    update();
}

void PreviewWidget::paintEvent(QPaintEvent *)
{
    QPainter painter(this);
    painter.scale( _zoomFactor, _zoomFactor );
    painter.translate( -_viewOffset );
    painter.drawPixmap( 0,0, image );
}

void PreviewWidget::mousePressEvent(QMouseEvent * me)
{
    isDragging = true;
    _dragStart = me->posF();
}

void PreviewWidget::mouseMoveEvent(QMouseEvent *me)
{
    if ( isDragging )
    {
          [...omitted...]
    }
}

void PreviewWidget::mouseReleaseEvent(QMouseEvent *me)
{
    isDragging = false;
}

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

bool PreviewWidget::gestureEvent(QGestureEvent *event)
{
    if (QGesture *pinch = event->gesture(Qt::PinchGesture))
        pinchGesture(static_cast<QPinchGesture *>(pinch));
    return true;
}

void PreviewWidget::pinchGesture(QPinchGesture * gesture)
{
    _zoomFactor *= gesture->scaleFactor();
}

i have oimitted some extra methods which are not relevant. The point is my widget NEVER receive any gesture... Why is this? Can somebody help me?

I am building using Qt 4.7.3 for Symbian^3 and testing on a C6-01...

I cannot see the problem and i have been trying hard, also the imagegestures kinda work (pinch seems, other does not seems)

There are few known issues on certain devices with certain Qt versions:
