JavaFX: QuadCurve 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 class define following constructors to define QuadCurve UI component.

 

public QuadCurve()

public QuadCurve(double startX, double startY, double controlX, double controlY, double endX, double endY)

startX: the X coordinate of the start point

startY: the Y coordinate of the start point

controlX: the X coordinate of the control point

controlY: the Y coordinate of the control point

endX: the X coordinate of the end point

endY: the Y coordinate of the end point

 

Example

QuadCurve quadCurve1 = new QuadCurve();

QuadCurve quadCurve2 = new QuadCurve(50, 70, 250, 250, 350, 70);

 

Fxml example

<QuadCurve fx:id="quadCurve1"  fill="lightsalmon" stroke="black" strokeWidth="5"
        startX="50"
        startY="70"
        controlX="250"
        controlY="250"
        endX="350"
        endY="70"
        />
