VLineTo.setY(double value) has the following syntax.
public final void setY(double value)
In the following code shows how to use VLineTo.setY(double value) method.
/*from w w w.j a v a 2s . co m*/ import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; import javafx.scene.shape.VLineTo; import javafx.stage.Stage; public class Main extends Application { @Override public void start(final Stage stage) { stage.setTitle("HTML"); stage.setWidth(500); stage.setHeight(500); Scene scene = new Scene(new Group()); VBox root = new VBox(); Path path = new Path(); path.getElements().add(new MoveTo(50.0f, 0.0f)); VLineTo vlt = new VLineTo(50.0f); vlt.setY(.7); path.getElements().add(vlt); System.out.println(vlt.getY()); root.getChildren().addAll(path); scene.setRoot(root); stage.setScene(scene); stage.show(); } public static void main(String[] args) { launch(args); } }
