將垂直行字母添加到游戲板GUI的更有效方法

我想知道是否有一種更簡單的方法可以將垂直標簽添加到游戲板上，而不是添加單獨的 Jlabels 并移動它們。我目前設定了一個字母，當我嘗試將字體大小更改為超過 10 種字體時，文本將變成一個小點或只是災難。

public class View {
    private JFrame frameMain;
    private JPanel panelBoard;
    private JPanel panelTitle;
    private JPanel panelMain;

    private JPanel panelY;

    private JPanel panel2;
    private JTextArea text;
    private JLabel jlabel;
    private JLabel jlabelY;
    private List<JButton> list;

    public View(){
        frameMain = new JFrame();
        frameMain.setLayout(new FlowLayout());
        list = new ArrayList<>();
        panelMain = new JPanel();
        panelY = new JPanel();
        panelY.setLayout(null);
        panelBoard = new JPanel();
        panelTitle = new JPanel();
        panelMain.setLayout(new BorderLayout());
        Board x = new Board();
        GridLayout grid = new GridLayout(15,15);
        x.createBoard();
        panelBoard.setLayout(grid);

        for (int i = 0; i < 15; i  ) {
            for (int j = 0; j < 15; j  ) {
                list.add(new JButton());
            }
        }
        for(JButton x5:list){
            panelBoard.add(x5);
        }

        jlabel = new JLabel("game");
        jlabelY = new JLabel("A");
        Dimension size = jlabelY.getPreferredSize();
        jlabelY.setBounds(17,10 ,size.width,size.height);
        jlabelY.setFont(new Font("Ariel", Font.BOLD, 10));

        panelTitle.setPreferredSize(new Dimension(50,50));
        panelY.setPreferredSize(new Dimension(25,600));
        panelBoard.setPreferredSize(new Dimension(400,400));
        panelMain.setPreferredSize(new Dimension(600,600));
        panelY.add(jlabelY);
        panelTitle.add(jlabel);
        panelMain.add(panelTitle, BorderLayout.NORTH);
        panelMain.add(panelBoard, BorderLayout.CENTER);
        panelMain.add(panelY,  BorderLayout.WEST);
        frameMain.add(panelMain);
        frameMain.setSize(600, 600);
        frameMain.pack();
        frameMain.setVisible(true);
    }

uj5u.com熱心網友回復：

您“可以”使用 a 來執行此操作GridLayout，但其中的樂趣在哪里。以下示例使用GridBagLayout來布局文本和按鈕。

嘗試跨包含對齊組件是，好吧，讓我們“硬”并把它留在那里，行標簽和按鈕被添加到同一個容器中。這確保了每行的高度基于行內組件的需要。

還有其他幾種方法可以做到這一點，但這給了你基本的想法。
