如何在 Java 中使用 JPanel 创建 Futoshiki GUI? [英] How to create a Futoshiki GUI using JPanel in Java?

问题描述

我目前正在为 Futoshiki 游戏开发 GUI.我已经设法用数字方块显示板.但是，我想知道如何实现具有大于和小于符号的关系平方.非常感谢您的帮助.

这就是我的 GUI 现在的样子.

基本上类似于下图.

这是我的代码...

public FutoshikiGUI(){整数行，列；grid = new JPanel(new GridLayout(5,5));单元格 = 新 PanelCell[5+1][5+1];for (row=1; row<=5; row++){for (col=1; col<=5; col++){单元格[row][col] = new PanelCell(this,row,col);grid.add(cells[row][col]);}}setLayout(new BorderLayout());添加(网格，BorderLayout.NORTH)；}公共面板单元(FutoshikiGUI p，int r，int c){如果(p == 空)throw new FutoshikiException(不能有空面板");如果 ((r<1) || (r>5))throw new FutoshikiException("无效行(" + r + ")");如果 ((c<1) || (c>5))throw new FutoshikiException("invalid col(" + c + ")");面板 = p;行 = r;列 = c;设置水平对齐(中心)；setMargin(新插入(5,5,5,5))；设置前景(颜色.黑色)；设置字体(字体)；setPreferredSize(new Dimension(75,75));}

解决方案

根据要求.下面的代码只是显示您想要的 Futoshiki 拼图

I'm currently working on my GUI for a Futoshiki game. I've managed to display the board with the number squares. However, I'd like to know how I would implement the relational squares that have the greater and less than symbols. Would really appreciate the help.

This what my GUI currently looks like now.

Basically something resembling the picture below.

Here is my code...

public FutoshikiGUI()
{
    int row, col;
    grid  = new JPanel(new GridLayout(5,5));
    cells = new PanelCell[5+1][5+1];
 
    for (row=1; row<=5; row++) 
    {
      for (col=1; col<=5; col++) 
      {
        cells[row][col] = new PanelCell(this,row,col);
        grid.add(cells[row][col]);
      }
    }
       
    setLayout(new BorderLayout());
    add(grid, BorderLayout.NORTH);
}

public PanelCell(FutoshikiGUI p,  int r, int c)
{
    if (p == null)
     throw new FutoshikiException("cannot have null panel");
    if ((r<1) || (r>5))
      throw new FutoshikiException("invalid row (" + r + ")");
    if ((c<1) || (c>5))
      throw new FutoshikiException("invalid col (" + c + ")");
      
    panel = p;
    row   = r;
    col   = c;
        
    setHorizontalAlignment(CENTER);
    setMargin(new Insets(5,5,5,5));
    setForeground(Color.black);
    setFont(font);
    setPreferredSize(new Dimension(75,75));
}

解决方案

As requested. The below code simply displays your desired Futoshiki puzzle board.

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.EventQueue;
import java.awt.GridLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Futoshiki implements Runnable {

    @Override
    public void run() {
        showGui();
    }

    private JPanel createGrid() {
        JPanel panel = new JPanel(new GridLayout(0, 9));
        // First row
        panel.add(new JButton("4"));
        panel.add(createColorButton("", Color.white, null));
        panel.add(new JButton());
