ArcBuilder.radiusY(double x) has the following syntax.
public B radiusY(double x)
In the following code shows how to use ArcBuilder.radiusY(double x) method.
import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.Arc; import javafx.scene.shape.ArcBuilder; import javafx.scene.shape.ArcType; import javafx.stage.Stage; //w ww. j av a 2 s . c o m public class Main extends Application { public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage primaryStage) { Group root = new Group(); Scene scene = new Scene(root, 551, 400, Color.BLACK); Group buttonGroup = new Group(); Arc rightButton = ArcBuilder.create() .type(ArcType.ROUND) .centerX(12) .centerY(16) .radiusX(15) .radiusY(15) .startAngle(180-30) .length(60) .fill(new Color(1,1,1, .90)) .translateX(40) .build(); buttonGroup.getChildren().add(rightButton); root.getChildren().add(buttonGroup); primaryStage.setScene(scene); primaryStage.show(); } }
