我有四个面板是从单个面板“模具”动态创建的，每个面板都有从数组设置的不同信息。问题是，当信息更新时，只有集合中的最后一个面板发生了变化。

示例：有一个 MovesLeft 标签，清楚地显示了剩余的移动次数。随着数字的下降，为该玩家列出的数字应该会发生变化，每个玩家都有自己的面板。目前只有最后一个面板的 Moveleft 标签会更改，并且对于移动的任何玩家都不会更改，而不仅仅是最后一个玩家。因此，如果玩家 1 用尽了所有动作，它将在玩家 4 的面板上显示 0，而不是在玩家 1 的面板上。

问题：有没有办法让我指定要更改标签的四个实例中的哪一个，以便更新正确的玩家信息？

如何将面板添加到 GUI

final JTabbedPane characterInfoPane = new JTabbedPane();
    while (setupPlayerIndex < 4) {
        JComponent panel = makeTextPanel("");
        characterInfoPane.addTab(minirpg.MiniRPG.players.get(setupPlayerIndex).getName(), null, panel,
                "");
        setupPlayerIndex++;
    }

我目前如何尝试更改 x 是所选播放器的相关标签

movesLeft.setText(Integer.toString(MiniRPG.players.get(x).getMoves()));

请让我知道是否需要添加代码来回答是否可以做我正在寻找的问题。

每次创建新文本窗格时，都会重新分配变量引用。也就是说，movesLeft将始终引用您创建的最后一个面板。

makeTextPane我将创建一个包含所有生成信息的自定义面板，而不是在 中创建面板makeTextPane。

然后，我将为您需要获取和更新的所有相关信息制作 setter 和 getter。

例如

protected class TextPane extends JPanel {

    private JLabel name;
    private JLabel icon;
    private JLabel lblClass;
    private JLabel pClass;
    private JLabel lblRole;
    private JLabel role;
    private JLabel lblStr;
    private JLabel str;
    private JLabel lblDex;
    private JLabel dex;
    private JLabel lblEnd;
    private JLabel end;
    private JLabel wiz;
    private JLabel lblHp;
    private JLabel health;
    private JLabel lblMoves;
    private JLabel movesLeft;
    private JLabel lblSkill1;
    private JButton skill1;
    private final JLabel lblSkill2;
    private final JButton skill2;
    private final JLabel lblSkill3;
    private final JButton skill3;
    private final JLabel lblSkill4;
    private final JButton skill4;

    public TextPane() {

        //add(filler);
        setLayout(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();

        JLabel dash;

        name = new JLabel(MiniRPG.MiniRPG.players.get(setupPlayerIndex).getName());
        c.insets = new Insets(5, 5, 5, 5);
        c.gridx = 0;
        c.gridy = 1;
        c.gridwidth = 2;
        add(name, c);

        icon = new JLabel(MiniRPG.players.get(setupPlayerIndex).getIcon());
        c.gridx = 1;
        c.gridy = 2;
        add(icon, c);

        c.gridwidth = 4;
        c.gridx = 1;
        c.gridy = 5;
        add(dash, c);

        lblStr = new JLabel("Strengh:");
        c.gridwidth = 2;
        c.gridx = 1;
        c.gridy = 6;

        add(lblDex, c);

        wiz = new JLabel(Integer.toString(

        c.gridwidth = 1;
        c.gridx = 3;
        c.gridy = 9;
        add(wiz, c);

        lblHp = new JLabel("HP: ");
        c.gridx = 1;
        c.gridy = 10;
        add(lblHp, c);


        health = new JLabel(Integer.toString(
                MiniRPG.MiniRPG.players.get(setupPlayerIndex).getHp()));
        c.gridx = 2;
        c.gridy = 10;
        add(health, c);

        lblMoves = new JLabel("Moves Left: ");
        c.gridx = 1;
        c.gridy = 11;
        add(lblMoves, c);

        movesLeft = new JLabel(Integer.toString(
                MiniRPG.players.get(setupPlayerIndex).getMoves()));
        c.gridx = 2;
        c.gridy = 11;
        add(movesLeft, c);

        dash = new JLabel("--------------------SKILLS--------------------");
        c.gridwidth = 4;
        c.gridx = 1;
        c.gridy = 12;
        add(dash, c);

        lblSkill1 = new JLabel("Skill 1:");
        c.gridwidth = 1;
        c.gridx = 1;
        c.gridy = 13;
        add(lblSkill1, c);

        skill1 = new JButton(MiniRPG.players.get(setupPlayerIndex).getSkill1());
        c.gridx = 2;
        c.gridy = 13;
        add(skill1, c);

        lblSkill2 = new JLabel("Skill 2:");
        c.gridx = 1;
        c.gridy = 14;
        add(lblSkill2, c);

        skill2 = new JButton(MiniRPG.players.get(setupPlayerIndex).getSkill2());
        c.gridx = 2;
        c.gridy = 14;
        add(skill2, c);
        skill2.setEnabled(false);

        lblSkill3 = new JLabel("Skill 3:");
        c.gridx = 1;
        c.gridy = 15;
        add(lblSkill3, c);

        skill3 = new JButton(MiniRPG.players.get(setupPlayerIndex).getSkill3());
        c.gridx = 2;
        c.gridy = 15;
        add(skill3, c);
        skill3.setEnabled(false);

        lblSkill4 = new JLabel("Skill 4:");
        c.gridx = 1;
        c.gridy = 16;
        add(lblSkill4, c);

        skill4 = new JButton(MiniRPG.players.get(setupPlayerIndex).getSkill4());
        c.gridx = 2;
        c.gridy = 16;
        add(skill4, c);
        skill4.setEnabled(false);

        skill1.addActionListener(e);
        skill2.addActionListener(e);
        skill3.addActionListener(e);
        skill4.addActionListener(e);

    }

    public void setMovesLeft(int value) {
        movesLeft.setText(Integer.toString(value));
    }

}

然后，我会在创建每个窗格时保留它的单独引用

final JTabbedPane characterInfoPane = new JTabbedPane();

TextPane[] textPanes = new TextPane[4];
while (setupPlayerIndex < 4) {
    textPanes[setupPlayerIndex] = new TextPane();
    characterInfoPane.addTab(minirpg.MiniRPG.players.get(setupPlayerIndex).getName(), null, textPanes[setupPlayerIndex],
            "");
    setupPlayerIndex++;
}

然后，这将允许我通过访问 setter 来更改特定玩家的移动TextPane

textPanes[x].setMovesLeft(MiniRPG.players.get(x).getMoves());
