Java列问题中的GridBagLayout

我正在尝试使用GridBagLayout布局管理器来实现这一点：

然而，我目前得到的是：

问题是橙色和棕色/灰色面板应该占据第二列，但似乎只想在运行代码时占据第三列

我用于布局的代码：

 Container contentPane = form.getContentPane();
    contentPane.setLayout(new GridBagLayout());
    GridBagConstraints c = new GridBagConstraints();

    JPanel pnlGame = new JPanel();
    pnlGame.setBackground(Color.green); //temp
    c.gridx = 0;
    c.gridy = 0;
    c.gridwidth = 2;
    c.gridheight = 2;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.85;
    c.weighty = 0.65;
    contentPane.add(pnlGame, c);

    JPanel pnlBuy = new JPanel();
    c.gridx = 2;
    pnlBuy.setBackground(Color.blue); //temp
    c.gridy = 0;
    c.gridwidth = 1;
    c.gridheight = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.15;
    c.weighty = 0.46;
    contentPane.add(pnlBuy, c);

    JPanel pnlUpgrade = new JPanel();
    pnlUpgrade.setBackground(Color.yellow); //temp
    c.gridx = 2;
    c.gridy = 1;
    c.gridwidth = 1;
    c.gridheight = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.15;
    c.weighty = 0.19;
    contentPane.add(pnlUpgrade, c);

    JPanel pnlStats = new JPanel();
    pnlStats.setBackground(Color.red); //temp
    c.gridx = 0;
    c.gridy = 2;
    c.gridwidth = 1;
    c.gridheight = 2;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.61;
    c.weighty = 0.35;
    contentPane.add(pnlStats, c);

    JPanel pnlSpeed = new JPanel();
    pnlSpeed.setBackground(Color.orange); //temp
    c.gridx = 1;
    c.gridy = 2;
    c.gridwidth = 2;
    c.gridheight = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.38;
    c.weighty = 0.04;
    contentPane.add(pnlSpeed, c);

    JPanel pnlRounds = new JPanel();
    pnlRounds.setBackground(Color.gray); //temp
    c.gridx = 2;
    c.gridy = 3;
    c.gridwidth = 2;
    c.gridheight = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.38;
    c.weighty = 0.31;
    contentPane.add(pnlRounds, c);

那么，我做错了什么？对不起，如果我的英语有点差劲，和/或我犯的错误是显而易见的。。。现在是早上20点到5点，我已经度过了漫长的一天。应该很快就会开始干了

更新：

看起来，如果我更改棕色/灰色面板的网格宽度，所有内容似乎都正确对齐，但最终在布局中出现了一个令人讨厌的间隙。在这里：

以及小组守则（包括Kevin S建议的修正案）：

那么，有没有什么我做错了，或者这只是GridBagLayout的一些怪异行为，我将不得不忍受

不幸的是，多亏了我的编辑，我已经失去了所有的嵌入，巴拉尔好心地放在那里。那么，恐怕我们回到了图片链接。现在看来，我不能发布超过两个超链接，所以在最后一个链接中，该链接已被删除，您需要复制并粘贴它

谢谢，Sam

看来您需要修复pnlRounds JPanel：

JPanel pnlRounds = new JPanel();
pnlRounds.setBackground(Color.gray); //temp
c.gridx = 1; // NEEDS TO BE 1 (NOT 2)
c.gridy = 3;
c.gridwidth = 2;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.38;
c.weighty = 0.31;
contentPane.add(pnlRounds, c);

看起来你的问题是，当

c.gridx=1

应该存在时，你的代码中有

c.gridx=2

---

另外，正如旁注，底部面板的权重X不会增加到1.00，而是增加到0.99。只是觉得你应该知道

不完全是你的解决方案，更像是一个临时解决办法。如果添加此新面板

    JPanel pnlTemp = new JPanel();
    pnlTemp.setBackground(Color.pink); //temp
    c.gridx = 1;
    c.gridy = 3;
    c.gridwidth = 1;
    c.gridheight = 1;
    c.fill = GridBagConstraints.BOTH;
    c.weightx = 0.38;
    c.weighty = 0.31;
    contentPane.add(pnlTemp, c);

使用灰色面板后，它将修复布局。不知道为什么，但在你（或其他人）能够找到正确的解决方案之前，这可能会有所帮助。这个新的粉红色面板不可见，但只是帮助修复了布局。下面是之后的布局

---

中间列中的所有组件至少也在另一列中。因此GridBagLayout将中间列的首选宽度计算为0，这就是您看到的效果

---

如果要确保中间的列具有更大的宽度，请在其中放置一些仅在此列中的组件。

是否只希望布局正常

我做了一些修改

 Container contentPane = form.getContentPane();
     contentPane.setLayout(new GridBagLayout());
     GridBagConstraints c = new GridBagConstraints();

     JPanel pnlGame = new JPanel();
     pnlGame.setBackground(Color.green); //temp
     c.gridx = 0;
     c.gridy = 0;
     c.gridwidth = 1; // one row
     c.gridheight = 1; // one column
     c.fill = GridBagConstraints.BOTH;
     c.weightx = 0.60;
     c.weighty = 0.40;
     contentPane.add(pnlGame, c);

     // Added two new components
     // pnlgGame and pnlggGame

     // Covers up 2nd column and rows 0 and 1
     JPanel pnlgGame = new JPanel();
     pnlgGame.setBackground(Color.green); //temp
     c.gridx = 1;
     c.gridy = 0;

     c.fill = GridBagConstraints.BOTH;
     c.weightx = 0.40;

     pnlStats.setBackground(Color.red); //temp
     c.gridx = 0;

     c.fill = GridBagConstraints.BOTH;
     c.weightx = 0.40;
     c.weighty = 0.35;
     contentPane.add(pnlRounds, c);

     form.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     form.setVisible(true);

我已经做了您建议的两个修改（修正了列问题，并使底部权重x加起来为1），但输出仍然相同且不正确。对不起，谢谢你的帮助/谢谢目前我已经实施了这个变通方法，这样我就可以专注于程序的其余部分。对我来说，这看起来确实是GridBagLayout中的一个bug。事实上，Paŭlo Ebermann的回答解释了添加此临时面板如何修复布局。ŭlo感谢这一点，我现在理解了这个问题。
