◆ center()

QPointF xmpsolve::RootsRenderer::center ( )

inline

center returns the current center point of the plot.

Returns: A QPointF object representing the real and imaginary part of the current center.

QPointF xmpsolve::RootsRenderer::scalePoint	(	QPointF	point,
		int	width,
		int	height )

protected

scalePoint is used internally to scale, flip and translate a point in a such a way that is plotted properly on the coordinate system on the screen.

Parameters

point	Is the original point that shall be plotted.
width	Is the current width of the widget.
height	Is the current height of the widget.

void xmpsolve::RootsRenderer::setCenter	(	double	x,
		double	y )

setCenter selects the current centered point.

Parameters

x	Horizontal coordinate of the center (aka real part)
y	Vertical coordinate of the center (aka imaginary part).
