JavaFX Quad Curve

Quad curve is a plain curve of order two. This is different from Cubic Curve in the sense that it doesn't have two control points like cubic curve. It rather has a single control point (X,Y).

In JavaFX, we can instantiate javafx.scene.shape.QuadCurve class to create a Quad curve. The class contains various properties which are defined in the table below. The class also contains the setter methods which can be used to set the properties to get the quad curve according to our requirements.

Properties

The properties of the class along with their setter methods are given in the table below.

Property	Description	Setter Method
controlX	X coordinate of the control point of quad curve	setControlX(Double)
controlY	Y coordinate of the control point of quad curve	setControlY(Double)
endX	X coordinate of the end point of quad curve	setEndX(Double)
endY	Y coordinate of ending point of quad curve	setEndY(Double)
startX	X coordinate of starting point of quad curve	setStartX(Double)
startY	Y coordinate of starting point of quad curve	setStartY(Double)

Example

package application; 
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.DropShadow;
import javafx.scene.paint.Color;
import javafx.scene.shape.QuadCurve;
import javafx.stage.Stage;
public class Shape_Example extends Application {

  @Override
  public void start(Stage primarystage) {
    Group root = new Group();
    primarystage.setTitle("QuadCurve Example");
    QuadCurve c = new QuadCurve();
    c.setStartX(70);
    c.setStartY(30);
    c.setControlX(250);
    c.setControlY(50);
    c.setFill(Color.RED);
    c.setEffect(new DropShadow());
    c.setEndX(250);
    c.setEndY(300);
    root.getChildren().add(c);
    Scene scene = new Scene(root,300,400);
    primarystage.setScene(scene);
    primarystage.show();
  }

  public static void main(String[] args) {
    launch(args);
  }
}
