I find the question that I use the QPainter to draw the polygon in those days.I write the programme and compile it then find the question that is no matching function for call to "QPainter::drawConvexPolygon".I refer to the qpainter.h then I find that there are no "QPainter::drawConvexPolygon" in the qpainter.h.
What can I to do?
Who can help me?
Thanks.
