How to draw a solid color ellipse (no black border) with QPainter

Code to start:

QColor yellow("#f0d048");
Qt::BrushStyle style = Qt::SolidPattern;
QBrush brush(yellow, style);
painter.setBrush(brush);
painter.drawEllipse(10,10,10,10);

      

        
        
        
      

    

Every time I do this, I get a yellow circle surrounded by a 1 pixel black border. In general, the circle will be the same size as if I painted with black, so what should I do to just get a solid yellow circle without a black border?
