A Polyline is an open figure formed using n number of lines existing in the same plane. i.e. a polyline is the same as a polygon except it is not closed. In JavaFX a polyline is represented by the javafx.scene.shape.PolyLine class.
To create a polygon you need to −
Instantiate this class.
Pass the start and endpoints, of the line segments to draw a polygon to the class either by passing them as arguments to the constructor or, using the getPoints() method as −
polygon.getPoints().addAll(new Double[]{ List of XY coordinates separated by commas });
Add the created node (shape) to the Group object.
Example
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.stage.Stage; import javafx.scene.shape.Polyline; public class DrawingPolyLine extends Application { public void start(Stage stage) { //Drawing a polygon Polyline poliline = new Polyline(); //Setting the properties of the ellipse poliline.getPoints().addAll(new Double[]{ 150.0, 200.0, 410.0, 200.0, 250.0, 50.0, 250.0, 230.0 }); //Setting other properties poliline.setStrokeWidth(8.0); poliline.setStroke(Color.DARKSLATEGREY); //Setting the Scene Group root = new Group(poliline); Scene scene = new Scene(root, 595, 300, Color.BEIGE); stage.setTitle("Drawing Polyline"); stage.setScene(scene); stage.show(); } public static void main(String args[]){ launch(args); } }
