basically I am trying to implement the Hover event on a QPointF, I need it to be clickable or at least being highlighted in some way.

What I've tried is to create a custom point starting by inheriting from QPointF, and then added hover,enter and leave methods as described in this tutorial, but it is not working. Also, the tut is based on generic QWidget and not specifically on points.

have you guys some hints/resources? google points me on a few tuts that are not useful, and the Qt page referred to HoverEvent is not tailored with examples.

thanks!

EDIT

More info needed. I am trying to draw a rectangle in a scene. The rectangle is of type QPolygonF and the scene is a QGraphicsScene type.

below the code block used to create a polygon from a list of points and its inclusion in the scene:

void

MyDialog::paintEvent(QPaintEvent *event)

{

  Q_UNUSED(event);

  QPolygonF poly;

  QPointF first;



  for(int i = 0;i < points->size();i++)

  {

       double length = points->at(i).split(",").at(0).toDouble();

       double rad = qDegreesToRadians( points->at(i).split(",").at(1).toDouble());



       QPointF pt(length * qCos(rad),length * qSin(rad));

       if(i == 0) first = pt;



       poly << pt;

  }

    poly << first;





  scene->addPolygon(poly,QPen(),QBrush(Qt::green,Qt::SolidPattern));



}

QPointF is a data object; it does not provide any graphical representation whatsoever (and I would strongly advise you against inheriting from it to add one).

One way to possibly do it is to override the QGraphicsScene::mouseMoveEvent() and QGraphicsScene::mousePressEvent() functions, allowing you to listen-in on where the user moves and clicks, and reacting on that. There are probably better ways to do this, though - I've only needed to react on clicks (and not on hovers) so far, so my experiences are limited.
