ellipse->setPos(X,Y) gives me an error.

I had it working last week, but then I changed something and now I get:

invalid use of incomplete type ‘class QGraphicsEllipseItem’
                           ellipse->setPos(X,Y);

                                  ^

In the contstructor:

  scene = new QGraphicsScene(this);
  ui->graphicsView_1->setScene(scene);

  QBrush greenBrush(Qt::green);
  QBrush yellowBrush(Qt::yellow);
  QBrush redBrush(Qt::red);
  QBrush greyBrush(Qt::gray);
  QPen outlinePen(Qt::black);
  outlinePen.setWidth(0);

  rectangle = scene->addRect(0, 0, 140, 140, outlinePen, redBrush);
  rectangle = scene->addRect(40, 40, 100, 100, outlinePen, greenBrush);
  rectangle = scene->addRect(60, 60, 80, 80, outlinePen, greyBrush);
  ellipse = scene->addEllipse(50, 50, 10, 10, outlinePen, yellowBrush);

And header file:

    QGraphicsScene *scene;
    QGraphicsRectItem *rectangle;
    QGraphicsEllipseItem *ellipse;
    QGraphicsLineItem *horizontalLine, *verticalLine;
    QGraphicsView *graphicsView_1;

It are 3 colored rectangled with a yellow dot in the middle. The dot gets drawn but I need it to move around when a machine sends data. I am trying to use the setPos() function but that gives the error.

What am I doing wrong

@bask185 Did you include QGraphicsEllipseItem header file where you call ellipse->setPos(X,Y)?
