I have drawn horizontal line and vertical line in QFrame using
painter.drawLine(195,395,195,10);//horizontal line
painter.drawLine(385,195,5,195);//vertical line
painter.drawLine(195,395,195,10);//horizontal line
painter.drawLine(385,195,5,195);//vertical line
To copy to clipboard, switch view to plain text mode
now the centre of the co-ordinate sytem is (195,195) .
The circle center may be anything but it should fit in the co-ordinate system it may
lie in the 1st,2nd, 3rd or 4th quadrant or may be in the centre.How do i proceed further??
