A tip of simulation elevator

Hello to all. I would like to practice in programming in C + + using Qt. As an example I would like to program the simulation of a elevator. Wanting to use the graphics to visualize the movement of the elevator that goes up to the plan you choose, what is best to use for animation, QPaint, or QGraphicsView-QGraphicsScene-QGraphicsItem or what other choice ?

Mine is QGraphicsView-QGraphicsScene-QGraphicsItem.. So I don't need to choose any other.

Couple of custom widgets moving around using QPropertyAnimation

That is a great news. I am up for it.

i don't know correct solutions for your question.. QPropertyAnimation its may be use.
