add points/path to QGraphicsView

[szisziszilvi]

Hello,

I'm on to learn the usage of QGraphicsView, and the main goal would be to draw diagrams of some data, so the best would be if I could give points (or better dreams: paths) to the object.

Now this works fine:

QGraphicsScene *scene =  new QGraphicsScene;
scene->addLine(0,0,50,30,QPen(QColor(0,0,0)));
scene->addEllipse(10,20,50,60);
ui->graphicsView->setScene(scene);

QGraphicsScene *scene =  new QGraphicsScene;
scene->addLine(0,0,50,30,QPen(QColor(0,0,0)));
scene->addEllipse(10,20,50,60);
ui->graphicsView->setScene(scene);

To copy to clipboard, switch view to plain text mode 

but I can't figure out how could I add simple points, or how to combine it with eg. QPainter. Or if I'm rihgt there would be a way through addItem, but I'm not very familiar with it's logic, and the examples in the Help are too complicated to avoid losting in the forest.

Regards
