FitInView is not allowing me to zoom GraphicsScene

[wagmare]

Hi Friends,

I made a QGraphicsView of size (0, 0, 1024, 1024)
and QGraphicsScene of size (0, 0, 2048, 2048)

i drawn some grid lines on the scene using
drawForeground(QPainter *painter, const QRectF &rect)

and now to make the scene to fit with the view
i used

View::resizeEvent(QResizeEvent *event)
{
      QGraphicsView::resizeEvent(event);
    fitInView(scene()->sceneRect(), Qt::KeepAspectRatio);
}

View::resizeEvent(QResizeEvent *event)
{
      QGraphicsView::resizeEvent(event);
    fitInView(scene()->sceneRect(), Qt::KeepAspectRatio);
}

To copy to clipboard, switch view to plain text mode 

and then i implemented zoom in the scene with

void View::wheelEvent(QWheelEvent *e)
{
 
   qreal factor = pow((double)2, -e->delta() / 240.0);
 
    zoom(factor);
}
 
void View::zoom(qreal factor)
{
 
 
    scale(factor, factor);
 
}

void View::wheelEvent(QWheelEvent *e)
{

   qreal factor = pow((double)2, -e->delta() / 240.0);

    zoom(factor);
}

void View::zoom(qreal factor)
{


    scale(factor, factor);
    
}

To copy to clipboard, switch view to plain text mode 

this zooming is not working for enlarging .
if i remove the fitInView it allowing to zoom but scene looks bigger than view .

Please help me

Thanks in Advance

I tried your code ,,,its working fine ..I am able to enlarge without removing fitinView from resizeevent handler.
