Java FXML问题 - 没有生成行

标签： java eclipse user-interface javafx fxml

作为一名编程学生，我有一些项目正在进行中。一个项目是旅行商问题。 （https://en.wikipedia.org/wiki/Travelling_salesman_problem）。我有一个JAVAFX GUI的问题。我不知道如何在fxml中实现for循环，因为我需要从已检查城市到另一个已检查城市的所有行。 [1]：https://i.stack.imgur.com/wb8h3.png（已检查的城市是苏黎世，格拉鲁斯和贝林佐纳 - ＆gt;所以我需要一些线来连接它们）。我只是想动态创建一些线条。所以你可以帮我解决这个问题吗？

这是控制器。

这是城市类：

package tsprealone;

/**

 * @author kbwschuler
 */
public class Stadt {

    private String name;
    private double xCoord;
    private double yCoord;
    private boolean isClicked;

    public Stadt(String name, double xCoord, double yCoord, boolean isClicked) {
        this.name = name;
        this.xCoord = xCoord;
        this.yCoord = yCoord;
        this.isClicked = isClicked;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getxCoord() {
        return xCoord;
    }

    public void setxCoord(int xCoord) {
        this.xCoord = xCoord;
    }

    public double getyCoord() {
        return yCoord;
    }

    public void setyCoord(int yCoord) {
        this.yCoord = yCoord;
    }

    public boolean isIsClicked() {
        return isClicked;
    }

    public void setIsClicked(boolean isClicked) {
        this.isClicked = isClicked;
    }


}

    public void start(Stage stage) throws Exception {
        FXMLDocumentController fx = new FXMLDocumentController();
        Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));

        Scene scene = new Scene(root);




        stage.setScene(scene);
        stage.show();
    }

    /**

            psNameToPathMap.set(null, new HashMap<String, String>());
        } catch (Exception e) {
        }




    }
