QTableWidget drop animation

Is there a way to change QTableWidget drop animation? Actually the animation is this: http://imgur.com/a/FGvIe

I tried this, but doesn't work:

Code:

class NewStyle : public QProxyStyle
{
public:
    NewStyle(QStyle *baseStyle = 0) : QProxyStyle(baseStyle)
    {
    }
 
    void drawPrimitive(PrimitiveElement element, const QStyleOption *option,
                       QPainter *painter, const QWidget *widget) const
    {
 
        if (element == QStyle::PE_IndicatorItemViewItemDrop && !option->rect.isNull()){
            QStyleOption opt(*option);
            opt.rect.setLeft(0);
            if (widget) opt.rect.setRight(widget->width());
            QProxyStyle::drawPrimitive(element, &opt, painter, widget);
            return;
        }
        else
        {
            // the default style is applied
            QProxyStyle::drawPrimitive(element, option, painter, widget);
        }
    }
 
};
