使用数字和字母调整国际象棋棋盘JavaFX的大小

Question

我正在尝试使用JavaFX制作一个棋盘。我想看起来像这张图片：在这里输入图像描述

package sample;

import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.VPos;
import javafx.scene.Scene;
import javafx.scene.control.Control;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.scene.layout.RowConstraints;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        GridPane root = new GridPane();
        final int size = 8 ;
        for (int row = 0; row < size; row++) {
            for (int col = 0; col < size; col ++) {
                StackPane square = new StackPane();
                String color ;
                if ((row + col) % 2 == 0) {
                    color = "white";
                } else {
                    color = "black";
                }
                square.setStyle("-fx-background-color: "+color+";");
                root.add(square, col, row);
            }
        }
        for (int i = 0; i < size; i++) {
            root.getColumnConstraints().add(new ColumnConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, HPos.CENTER, true));
            root.getRowConstraints().add(new RowConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, VPos.CENTER, true));
        }
        primaryStage.setScene(new Scene(root, 400, 400));
        primaryStage.show();
    }

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

在这个程序中，我定义了一个常数（大小）来决定棋盘的大小。它也可以从2到16（大小）的变化。如你所见，底面的字母不见了，右边的数字不见了。我如何添加它们？

我并不真正理解您的评论，但您可以简单地向GridPane添加另一列和另一行。用数字填充第一列。用字母填充最后一行。

package sample;

import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.VPos;
import javafx.scene.Scene;
import javafx.scene.control.Control;
import javafx.scene.control.Label;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.scene.layout.RowConstraints;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        GridPane root = new GridPane();
        final int size = 8 ;
        for (int row = 0; row < size; row++) {
            for (int col = 0; col <= size; col ++) {
                StackPane square = new StackPane();
                if (col == 0) {
                    Label label = new Label(String.valueOf(row + 1));
                    square.getChildren().add(label);
                }
                else {
                    String color;
                    if ((row + col) % 2 == 0) {
                        color = "white";
                    }
                    else {
                        color = "black";
                    }
                    square.setStyle("-fx-background-color: "+color+";");
                }
                root.add(square, col, row);
            }
        }
        StackPane square = new StackPane();
        Label label = new Label("A");
        square.getChildren().add(label);
        root.add(square, 1, 8);
        square = new StackPane();
        label = new Label("B");
        square.getChildren().add(label);
        root.add(square, 2, 8);
        square = new StackPane();
        label = new Label("C");
        square.getChildren().add(label);
        root.add(square, 3, 8);
        square = new StackPane();
        label = new Label("D");
        square.getChildren().add(label);
        root.add(square, 4, 8);
        square = new StackPane();
        label = new Label("E");
        square.getChildren().add(label);
        root.add(square, 5, 8);
        square = new StackPane();
        label = new Label("F");
        square.getChildren().add(label);
        root.add(square, 6, 8);
        square = new StackPane();
        label = new Label("G");
        square.getChildren().add(label);
        root.add(square, 7, 8);
        square = new StackPane();
        label = new Label("H");
        square.getChildren().add(label);
        root.add(square, 8, 8);
        for (int i = 0; i <= size; i++) {
            root.getColumnConstraints().add(new ColumnConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, HPos.CENTER, true));
            root.getRowConstraints().add(new RowConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, VPos.CENTER, true));
        }
        primaryStage.setScene(new Scene(root, 450, 400));
        primaryStage.show();
    }

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

这就是我运行它时的样子。
