Arc.getRadiusX() has the following syntax.
public final double getRadiusX()
In the following code shows how to use Arc.getRadiusX() method.
// ww w . ja va 2s. c o m 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.ArcType; import javafx.stage.Stage; public class Main extends Application { public static void main(String[] args) { Application.launch(args); } @Override public void start(Stage primaryStage) { primaryStage.setTitle("Text Fonts"); Group g = new Group(); Scene scene = new Scene(g, 550, 250,Color.web("0x0000FF",1.0)); Arc arc = new Arc(); arc.setCenterX(50.0f); arc.setCenterY(50.0f); arc.setRadiusX(25.0f); arc.setRadiusY(25.0f); arc.setStartAngle(45.0f); arc.setLength(270.0f); arc.setType(ArcType.ROUND); System.out.println(arc.getRadiusX()); g.getChildren().add(arc); primaryStage.setScene(scene); primaryStage.show(); } }
