The form contains A QGraphicsView to display a QGraphicsScene, The QGraphicsScene involves about 300,000 QGraphiceItems, these items are drawn on-fly with different color . I need to apply QtMultiThreading or any other technique that helps improving the project performance namely plotting the items, zooming the QGraphicsView, getting the iteminformation .
