You are using resizeEvent() to do what?

QGraphicsView::resizeEvent(event);
    fitInView(scene()->sceneRect(), Qt::KeepAspectRatio);

QGraphicsView::resizeEvent(event);
    fitInView(scene()->sceneRect(), Qt::KeepAspectRatio);

... and are you passing the event to the parent class so that normal resizing can be completed? One line in isolation is insufficient for us to know.

Thanks for the reply!!

no im not doing any thing other than that .. the graphicsView is my arch parent and im reimplementing the resize Event like this only ..
im showing this GraphicsView widget only ...

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

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

}

if u want more in the code

my scene representation ...

QGraphicsScene *scene = new QGraphicsScene(this);
    scene->setBackgroundBrush(QColor(80, 18, 60));
    scene->setItemIndexMethod(QGraphicsScene::NoIndex);
    scene->addItem(startButton);
 
    scene->setSceneRect(QRectF(0, 0, 1200, 1000) );

QGraphicsScene *scene = new QGraphicsScene(this);
    scene->setBackgroundBrush(QColor(80, 18, 60));
    scene->setItemIndexMethod(QGraphicsScene::NoIndex);
    scene->addItem(startButton);

    scene->setSceneRect(QRectF(0, 0, 1200, 1000) );

my view settings ..

setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    setMinimumSize(50, 50);
    setViewportUpdateMode(FullViewportUpdate);
    setCacheMode(CacheBackground);
    setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform | QPainter::TextAntialiasing);

setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    setMinimumSize(50, 50);
    setViewportUpdateMode(FullViewportUpdate);
    setCacheMode(CacheBackground);
    setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform | QPainter::TextAntialiasing);
