的GridBagLayout在Java中列问题

Question

我试图使用到的GridBagLayout布局管理器来实现这一目标：

然而，什么我目前得到的是这样的：

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用第三列。

，我使用的布局代码：

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，我究竟做错了什么？对不起，如果我的英语有点低落，或者我犯的错误是非常明显的......早上是20点到5点，而且我度过了漫长的一天。很可能很快就会碰到干草。

UPDATE：

看来，如果我改变了棕/灰面板的gridwidth，似乎一切都正确对齐，但我最终在我的布局讨厌的差距。在这里：

而对于面板的代码（包括凯文小号建议修订）：

JPanel pnlRounds = new JPanel(); 
pnlRounds.setBackground(Color.gray); //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(pnlRounds, c); 

那么，有没有什么，我做错了，还是这只是GridBagLayout的一些奇怪的行为，我将不得不忍受？

不幸的是，多亏了我的编辑，我已经失去了Bala R善意地放在那里的所有嵌入。所以，我们回到了图像的链接上，恐怕。而现在看来，我不能发布两个以上的超链接，那么该链接在最近一个被杀害，你需要复制和粘贴。

谢谢，山姆

Answer 1

所有在中间栏的部件至少在一个其他列好。因此，GridBagLayout将中间列的首选宽度计算为0，这就是您所看到的效果。

如果你想确保你的中间列有更多的宽度，把一些只在这个列中的组件。

Answer 2

所以它看起来像你需要修复的pnlRounds的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，你在你的代码有c.gridx = 2时c.gridx = 1是什么确实应该存在。另外，就像旁注一样，底部面板的weightx不会增加到1.00，它们会增加到0.99。只是觉得你应该知道。

Answer 3

并不完全是为了解决您的问题，而更像是临时的解决方法。如果你添加这个新的面板

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); 

灰色面板后，它修复了布局。不知道为什么，但也许这将有助于直到你（或其他人）能够找出正确的解决方案。这个新的粉色面板不可见，但只是有助于以某种方式修复布局。这里的布局是什么样后

你只是想布局工作？

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.gridwidth = 1; // one row 
    c.gridheight = 2; // two column 
    c.fill = GridBagConstraints.BOTH; 
    c.weightx = 0.20; 
    c.weighty = 0.40; 
    contentPane.add(pnlgGame, c); 

    // Covers 2nd row and column 1 
    JPanel pnlggGame = new JPanel(); 
    pnlggGame.setBackground(Color.green); //temp 
    c.gridx = 0; 
    c.gridy = 1; 
    c.gridwidth = 1; 
    c.gridheight = 1; 
    c.fill = GridBagConstraints.BOTH; 
    c.weightx = 0.60; 
    c.weighty = 0.20; 
    contentPane.add(pnlggGame, c); 


    JPanel pnlBuy = new JPanel(); 
    pnlBuy.setBackground(Color.blue); //temp 
    c.gridx = 2; 
    c.gridy = 0; 
    c.gridwidth = 1; 
    c.gridheight = 1; 
    c.fill = GridBagConstraints.BOTH; 
    c.weightx = 0.20; 
    c.weighty = 0.40; 
    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 = 0.20; 
    c.weighty = 0.20; 
    contentPane.add(pnlUpgrade, c); 

    JPanel pnlSpeed = new JPanel(); 
    pnlSpeed.setBackground(Color.BLUE); //temp 
    c.gridx = 1; 
    c.gridy = 2; 
    c.gridwidth = 2; 
    c.gridheight = 1; 
    c.fill = GridBagConstraints.BOTH; 
    c.weightx = 0.40; 
    c.weighty = 0.05; 
    contentPane.add(pnlSpeed, 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 = 0.60; 
    c.weighty = 0.40; 
    contentPane.add(pnlStats, c); 


    JPanel pnlRounds = new JPanel(); 
    pnlRounds.setBackground(Color.gray); //temp 
    c.gridx = 1; 
    c.gridy = 3; 
    c.gridwidth = 2; 
    c.gridheight = 1; 
    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);
