java - 自定义 Swing 布局

Question

我正在创建一个游戏并按照我想要的方式设置框架，我需要了解如何创建服装布局。我已经尝试创建多个具有不同布局的面板，例如 Flow 和 Border，并在主面板上添加面板，但我仍然没有得到想要的结果。我想要的在附图中显示。请告诉我是否有任何代码段有帮助。
问题:1. 是否可以得到这样的布局？ (我希望修复它。)

1. 在“按钮”下有您在图片中看到的 JLabel。我希望它的文本从左边开始，沿着列向下，从中间开始，然后到右边的列。这可能吗？

Answer 1

我在评论中写的内容略有不同，因为 BoxLayout 有点东西，我从不使用，因为我不擅长:-)

尽管我为克服这个缺点所做的工作是采用 2 个 JPanel，每个用于 JTextField 和 JButton 并且其余相同，如本例所示:

import java.awt.*;
import javax.swing.*;

public class LayoutExample {    

    private static final int GAP = 5;
    private static final int TOTAL_LABELS = 18;

    private JTextField tField;
    private JButton button;
    private JLabel[] labels;

    private void displayGUI () {
        JFrame frame = new JFrame ( "Layout Example" );
        frame.setDefaultCloseOperation ( JFrame.DISPOSE_ON_CLOSE );

        JPanel contentPane = getPanel ();
        contentPane.setLayout ( new BorderLayout ( GAP, GAP ) );

        JPanel headerPanel = getPanel ();
        headerPanel.setLayout ( new GridLayout ( 0, 1, GAP, GAP ) );
        JPanel textFieldPanel = getPanel ();
        tField = new JTextField ( 10 );
        textFieldPanel.add ( tField );
        JPanel buttonPanel = getPanel ();
        button = new JButton ( "Button" );
        buttonPanel.add ( button );     
        headerPanel.add ( textFieldPanel );
        headerPanel.add ( buttonPanel );
        contentPane.add (headerPanel, BorderLayout.PAGE_START );

        JPanel centerPanel = getPanel ();
        centerPanel.setLayout ( new GridLayout ( 0, 3, GAP, GAP ) );
        labels = new JLabel [ TOTAL_LABELS ];
        for ( int i = 0; i < labels.length; ++i ) {
            labels [ i ] = new JLabel ( String.valueOf ( i ), JLabel.CENTER );
            centerPanel.add ( labels [ i ] );
        }
        contentPane.add ( centerPanel, BorderLayout.CENTER );


        frame.setContentPane ( contentPane );
        frame.pack ();
        frame.setLocationByPlatform ( true );
        frame.setVisible ( true );
    }

    private JPanel getPanel () {
        JPanel panel = new JPanel ();
        panel.setOpaque ( true );
        panel.setBorder ( BorderFactory.createEmptyBorder ( GAP, GAP, GAP, GAP ) );

        return panel;
    }

    public static void main ( String[] args ) {
        Runnable runnable = new Runnable () {
            @Override
            public void run () {
                new LayoutExample ().displayGUI ();
            }
        };
        EventQueue.invokeLater ( runnable );
    }
}

输出:
