QGraphicsItemAnimation and QTimeLine

[ashukla]

thanks
when the value of the step in the setPosAt ( qreal step, const QPointF & point ) function is smaller(ie.nearer to zero) the animation occurs faster(i.e duration of animation is less) and when the value of step is set to bigger value (nearer to or equal to one ) , the animation animates slowly .

then why do we need the QTimeLine when we can control the duration of animation using setPosAt ( qreal step, const QPointF & point ).

For one pass of complete animation QTimeLine is used. It is a time (in millisec)for one pass of animation of object.
