问题描述
我和我的搭档正在为游戏编写这个程序.他为我们的网格使用了 GridBagLayout
,我正在尝试解决网格的一些问题.
My partner and I are writing this program for a game. He used GridBagLayout
for our grid and I'm trying to troubleshoot some problems with the grid.
代码如下:
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
@SuppressWarnings("serial")
public class NewGame extends JFrame{
private int width = 500, height = 500, xSquares = 4, ySquares = 4;
Font buttonFont = new Font("Times New Roman", Font.PLAIN, 15);
endGame end = new endGame();
public NewGame() {
super("OnO");
// gridbaglayout is flexible but kinda complicated
GridBagLayout Griddy = new GridBagLayout();
this.setLayout(Griddy);
JPanel p = new JPanel();
p.setLayout(Griddy);
this.add(p);
GridBagConstraints c = new GridBagConstraints();
c.fill = GridBagConstraints.BOTH;
c.weightx = 1;
c.weighty = 1;
c.gridwidth = 4;
c.gridheight = 4;
NewBoard board = new NewBoard(xSquares, ySquares);
// board at top left
c.gridx = 0;
c.gridy = 0;
this.add(board, c);
// find a way to make buttons smaller
JButton EndGame = new JButton("End");
EndGame.setBackground(Color.black);
EndGame.setForeground(Color.white);
EndGame.setFont(buttonFont);
EndGame.addActionListener(end);
JButton Undo = new JButton("Undo");
Undo.setBackground(Color.black);
Undo.setForeground(Color.white);
Undo.setFont(buttonFont);
JButton NewGame = new JButton("New Game");
NewGame.setBackground(Color.black);
NewGame.setForeground(Color.white);
NewGame.setFont(buttonFont);
// fit 3
c.gridwidth = 1;
c.gridheight = 1;
c.gridy = 3;
c.fill = GridBagConstraints.HORIZONTAL;
p.add(EndGame, c);
c.gridx = 2;
c.fill = GridBagConstraints.HORIZONTAL;
p.add(Undo, c);
c.gridx = 3;
c.fill = GridBagConstraints.HORIZONTAL;
p.add(NewGame, c);
this.setPreferredSize(new Dimension(width, height));
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.pack();
this.setLocation(450, 30);
this.setVisible(true);
}
public class endGame implements ActionListener {
public void actionPerformed(ActionEvent event) {
System.exit(0);
}
}
public class newGame implements ActionListener {
public void actionPerformed(ActionEvent event) {
}
}
}
当此代码与我们程序中的其他类一起运行时,endGame
、Undo
和 NewGame
按钮与棋盘重叠:
When this code is run with the other classes in our program, the endGame
, Undo
, and NewGame
buttons overlap with the board:
我想找到一种方法,在单独的空间中显示板子上方或下方的 3 个按钮,但我已经修改了很长时间的代码,但还没有找到解决方案.我不确定我应该在这里做什么.
I want to find a way to display the 3 buttons either above or below the board in its individual space, but I've tinkered with the code for a long time and can't find the solution yet. I'm not sure what I should be doing here.
推荐答案
首先,变量名不应以大写字符开头.学习并遵循 Java 命名约定.
First of all, variable names should NOT start with an upper case character. Learn and follow Java naming conventions.

最简单的解决方案是不对框架使用 GridBagLayout.
Simplest solution is to not use a GridBagLayout for the frame.
只需使用框架的默认BorderLayout
.然后,您可以将 JPanel 与 FlowLayout 用于按钮,并为板面板使用 GridLayout.
Just use the default BorderLayout
of the frame. Then you can use a JPanel with the FlowLayout for your buttons, and a GridLayout for your board panel.
基本逻辑是:
JPanel buttons = new JPanel();
buttons.add(endGame);
buttons.add(undo);
buttons.add(newGame);
this.add(button, BorderLayout.PAGE_START);
NewBoard board = new NewBoard(xSquares, ySquares);
this.add(board, BorderLayout.CENTER);
默认情况下,JPanel 使用 FlowLayout
,因此按钮将显示在一行上.
By default a JPanel uses a FlowLayout
so the buttons will be displayed on a single row.
