How to draw filled polygon on QGraphicsScene

chuanlau

I want to draw a polygon filled with a specific color on QGraphicsScene. Then I use the following codes:

QPolygonF poly;
poly << QPointF(10, 10) << QPointF(10, 50) << QPointF(30, 70 )<< QPointF(60, 50) << QPointF(50, 10);
QBrush brush;
brush.setColor(Qt::red);
QPen pen(Qt::green);
QGraphicsScene graphics_scene_ = new QGraphicsScene(0,0,200,200);
graphics_scene_->addPolygon(poly, pen, brush);
setScene(graphics_scene_);

However I only get a hollow polygon with green border, but without red fill inside the polygon.
How can I fix it?

I've finally figured out how to do.
Just adding

brush.setStype(Qt::SolidPattern);

works.
