Newbie problem with QGraphicsView

Message 1 in thread

Hi everyone,

i added a qgraphicsview to a qwidget and now i try to add a line to the scene but the program just hangs using the following code:
QBrush brush(QColor("black"));
QPen pen(brush, 1.0);
//QGraphicsScene scene;
QGraphicsScene *scene = _diagramWidget->scene();
QLineF xLine(0.0, 0.0, 100.0, 0.0);
QGraphicsLineItem *x = scene->addLine(xLine);
x->setPen(pen);
//_diagramWidget->setScene(&scene);
_diagramWidget->show();

As i am completely new to qgraphicsview and such i am happy for any help. BTW: i want to use qgraphicsview to draw a diagram. Maybe there are better/easier ways to accomplish this?

Thanks
Chris
