Best way to animate a circle moving around the screen in Qt?

Question

If I wanted to use Qt, just a few circles moved in a white rectangle or graph, what would be the best way?

Do I need to draw a white / graphic object where a circle moved each time? Is there an easy way to accomplish this in Qt?

Answer 1

• Create a QGraphicsView object for your widget and add a QGraphicsScene to view.
• Add QGraphicsEllipseItem object for the scene
• Use QPropertyAnimation to change the pos property of an ellipse element.

If you need more advanced features, you can create your own animation class in QPropertyAnimation.
