JavaFX有其他内置的形状，如

ArcCircleCubicCurveEllipseLinePathPolygonPolylineQuadCurveRectangleSVGPathText

以下代码显示了如何创建路径。

import javafx.application.Application;import javafx.geometry.Insets;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.control.CheckBox;import javafx.scene.layout.HBox;import javafx.scene.layout.StackPane;import javafx.scene.layout.VBox;import javafx.scene.shape.LineTo;import javafx.scene.shape.MoveTo;import javafx.scene.shape.Path;import javafx.stage.Stage;public class Main extends Application { public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { Scene scene = new Scene(new Group()); stage.setTitle("Checkbox Sample"); stage.setWidth(230); stage.setHeight(120); Path path = new Path(); path.getElements().add(new MoveTo(0.0f, 50.0f)); path.getElements().add(new LineTo(100.0f, 100.0f)); VBox vbox = new VBox(); vbox.getChildren().addAll(path); vbox.setSpacing(5); HBox root = new HBox(); root.getChildren().add(vbox); root.setSpacing(40); root.setPadding(new Insets(20, 10, 10, 20)); ((Group) scene.getRoot()).getChildren().add(root); stage.setScene(scene); stage.show(); }}

路径元素实际上从javafx.scene.shape.PathElement类扩展，它仅在Path对象的上下文中使用。

所以你不能实例化一个LineTo类放在场景图中。具有 To 作为后缀的类是路径元素，而不是Shape节点。

例如，MoveTo和LineTo对象实例是添加到Path对象的Path元素，而不是可以添加到场景的形状。

例子

以下代码显示了如何向路径添加 QuadCurveTo 。

import javafx.application.Application;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.shape.MoveTo;import javafx.scene.shape.Path;import javafx.scene.shape.QuadCurveTo;import javafx.stage.Stage;public class Main extends Application { @Override public void start(Stage stage) { Group root = new Group(); Scene scene = new Scene(root, 300, 150); stage.setScene(scene); stage.setTitle(""); Path path = new Path(); MoveTo moveTo = new MoveTo(); moveTo.setX(0.0f); moveTo.setY(50.0f); QuadCurveTo quadTo = new QuadCurveTo(); quadTo.setControlX(25.0f); quadTo.setControlY(0.0f); quadTo.setX(50.0f); quadTo.setY(50.0f); path.getElements().add(moveTo); path.getElements().add(quadTo);  root.getChildren().add(path); scene.setRoot(root); stage.show(); } public static void main(String[] args) { launch(args); }}

使用Path，MoveTo和CubicCurveTo创建曲线

import javafx.application.Application;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.shape.CubicCurveTo;import javafx.scene.shape.MoveTo;import javafx.scene.shape.Path;import javafx.stage.Stage;public class Main extends Application { public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { stage.setTitle("ComboBoxSample"); Scene scene = new Scene(new Group(), 450, 250); Path path = new Path(); MoveTo moveTo = new MoveTo(); moveTo.setX(0.0f); moveTo.setY(0.0f); CubicCurveTo cubicTo = new CubicCurveTo(); cubicTo.setControlX1(0.0f); cubicTo.setControlY1(0.0f); cubicTo.setControlX2(100.0f); cubicTo.setControlY2(100.0f); cubicTo.setX(100.0f); cubicTo.setY(50.0f); path.getElements().add(moveTo); path.getElements().add(cubicTo);  Group root = (Group) scene.getRoot(); root.getChildren().add(path); stage.setScene(scene); stage.show(); }}

减去两个形状以创建路径

import javafx.application.Application;import javafx.scene.Group;import javafx.scene.Scene;import javafx.scene.effect.DropShadow;import javafx.scene.effect.DropShadowBuilder;import javafx.scene.paint.Color;import javafx.scene.shape.*;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("Shapes"); Group root = new Group(); Scene scene = new Scene(root, 300, 300, Color.WHITE); Ellipse bigCircle = EllipseBuilder.create() .centerX(100) .centerY(100) .radiusX(50) .radiusY(75/2) .strokeWidth(3) .stroke(Color.BLACK) .fill(Color.WHITE) .build();  Ellipse smallCircle = EllipseBuilder.create() .centerX(100) .centerY(100) .radiusX(35/2) .radiusY(25/2)  .build(); Shape shape = Path.subtract(bigCircle, smallCircle); shape.setStrokeWidth(1); shape.setStroke(Color.BLACK); shape.setFill(Color.rgb(255, 200, 0)); root.getChildren().add(shape);  primaryStage.setScene(scene); primaryStage.show(); }}

使用VLineTo创建垂直线

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)); path.getElements().add(new VLineTo(50.0f)); root.getChildren().addAll(path); scene.setRoot(root); stage.setScene(scene); stage.show(); }  public static void main(String[] args) { launch(args); }}
