JavaFX多边形折线

多边形，一个简单的示例代码如下所示 -

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.shape.Polygon;
import javafx.stage.Stage;

public class Main extends Application {
// create w  w  W. y II  b Ai .c  o M
  @Override
  public void start(Stage stage) {
    Group root = new Group();
    Scene scene = new Scene(root, 260, 80);
    stage.setScene(scene);

    Group g = new Group();

    Polygon polygon = new Polygon();
    polygon.getPoints().addAll(new Double[]{
        0.0, 0.0,
        20.0, 10.0,
        10.0, 20.0 });

    g.getChildren().add(polygon);

    scene.setRoot(g);
    stage.show();
  }

  public static void main(String[] args) {
    launch(args);
  }
}
