hi! How we can refresh or update the graphics view to display the images continously

Thanks for watching my video. Follow the Below code. // Declare QGraphicsPixmapItem object globally to avoid memory leackage QGraphicsPixmapItem *item = new QGraphicsPixmapItem(nullptr); item->setPixmap("YOUR_PIXMAP_IMAGE"); scene->addItem(item); scene->setSceneRect("YOUR_IMAGE_SIZE"); ui->graphicsView->fitInView(scene->sceneRect(), Qt::KeepAspectRatio); ui->graphicsView->setRenderHints(QPainter::Antialiasing); ui->graphicsView->setScene(scene); ui->graphicsView->viewport()->update(); ui->graphicsView->update(); ui->graphicsView->show();
