How to Fill custom shape?

Hello ,

I have created arrow in the arc shape using the combination of drawArc() and moveTo() & lineTo() functions. But the problem is i am not able to fill the arrow with the specified color. I tired using fillPath() but of no use.

I have attached the picture of the object what i have drawn and also what i need. Please guide me how to fill.

Create QPainterPath using QPainterPath::lineTo() and QPainterPath::arcTo() and then use QPainter::fillPath().
