用数字和字母调整棋盘 JavaFX 的大小

Question

我正在尝试使用 javaFX 制作棋盘。我想看起来像这张照片： enter image description here

这是我的代码：

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，我定义了一个确定棋盘大小的常量（大小）。它也可以从 2 变为 16（大小）。如您所见，底部的字母缺失，右侧的数字缺失。我怎样才能添加它们？如果来自这里的代码： Chessboard with automatic resizing

Answer 1

我不太了解您的comment，但您可以简单地在GridPane 中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);
            }
        }
        for (int i = 1; i <= size; i++) {
            StackPane square = new StackPane();
            char[] letter = new char[]{(char) ('A' + (i - 1))};
            Label label = new Label(new String(letter));
            square.getChildren().add(label);
            root.add(square, i, size);
        }
        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));
        }
        int dim = (size + 1) * 50;
        primaryStage.setScene(new Scene(root, dim, dim));
        primaryStage.show();
    }

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

这是我运行它时的样子。

更新！ 我从以下答案中尝试了这段代码：

package sample;

        final int size = 10 ;
        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);

        }

        if(size==10){
            Label label = new Label("A");
            square.getChildren().add(label);
            root.add(square, 1, 10);
            square = new StackPane();
            label = new Label("B");
            square.getChildren().add(label);
            root.add(square, 2, 10);

            square = new StackPane();
            label = new Label("H");
            square.getChildren().add(label);

            square.getChildren().add(label);
            root.add(square, 9, 10);
            square = new StackPane();
            label = new Label("J");
            square.getChildren().add(label);
            root.add(square, 10, 10);
        }


        for (int i = 0; i <= size; i++) {
            root.getRowConstraints().add(new RowConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, VPos.CENTER, true));
            root.getColumnConstraints().add(new ColumnConstraints(5, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, HPos.CENTER, true));

        }
        primaryStage.setScene(new Scene(root, 450, 400));
        primaryStage.show();
    }

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

它正在工作，但这是一个好方法吗？
