Graphics2D g2d = ( Graphics2D ) g;

g2d.setColor( Color.red );

GeneralPath rect = new GeneralPath( GeneralPath.EVEN_ODD );

rect.moveTo( 300.0f, 300.0f ); // ul corner

rect.lineTo( 500.0f, 300.0f ); // ur corner

rect.lineTo( 500.0f, 400.0f ); // lr corner

rect.lineTo( 300.0f, 400.0f ); // ll corner
