public class QuadCurve
extends Shape

The Quadcurve class defines a quadratic Bézier parametric curve segment in (x,y) coordinate space. Drawing a curve that intersects both the specified coordinates (startX, startY) and (endX, enfY), using the specified point (controlX, controlY) as Bézier control point.
