Hi,

I'm drawing rects with QPainter. I want to create a tooltip or show a widget, if i hoover with the mouse over the painted rect. The class of QPainter does not seem to have any hoover events.

Any ideas would be welcome.
thanx Astronomy



static const QPointF points[4] = {
QPointF(10.0, 80.0),
QPointF(20.0, 10.0),
QPointF(80.0, 30.0),
QPointF(90.0, 70.0)
};


QPainter p;
p.begin(this);
p.setPen(Qt::black);
p.drawPolygon(points, 4);
p.end();

The QWidget or QGraphicsItem that you are drawing on has the event handlers.
