[Qt-interest] QGraphicsItem movement problem

[Riccardo Roasio]

Hi,

i'm implementing a movement of a QGraphicsItem due to mouse press and movement..

   currentMovement=event->pos().x();

     if(currentMovement<startMovement)
     {
      //movememnt is right to left
      int delta=startMovement-currentMovement;
      currentX=startX-delta;

      std::cout<<"DELTA : "<<delta<<std::endl;
      std::cout<<"currentX : "<<currentX<<std::endl;

      setPos(currentX,startY);
      update();
     }


the problem is that the effect is not so fluid, but the continuous
refresh create a blinking effect of the item..

I can i solve this problem?

Thanks,
Riccardo
