javafx.scene.shape.QuadCurve

All Implemented Interfaces:
  `Styleable, EventTarget`

public non-sealed 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.

    QuadCurve quad = new QuadCurve();
    quad.setStartX(0.0f);
    quad.setStartY(50.0f);
    quad.setEndX(50.0f);
    quad.setEndY(50.0f);
    quad.setControlX(25.0f);
