GridBagLayout + GridLayout 的 Java 问题

Question

我在使用 GridBagLayout 中的 GridLayout 时遇到问题。

我希望我的 GridLayout 适合 GridBagLayout 的宽度。

我做了一个说明我正在尝试做的事情：

但这是我得到的：

"Test, version : 1.5, Disponible" 是一个 1 列 3 行的 GridLayout。 “Mitramail，1.0 版，Disponible”是另一个 1 列和 3 行的 GridLayout。 我正在尝试将它们添加到另一个具有 x 行和 2 列的 GridLayout 中。所以通常它们应该彼此相邻，但它们是一个在另一个之下。

代码如下：

GridBagConstraints c = new GridBagConstraints();
c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 1;
c.anchor = GridBagConstraints.WEST;
c.weightx = 1;
panelDynamique.add(new JLabel("Disponible"), c);

c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 2;
c.fill = GridBagConstraints.HORIZONTAL;
panelDynamique.add(new JSeparator(), c);

panelDispo.setLayout(new GridLayout(this.getNbAppFor("Disponible") /*Variable X, replace by 2 for better understanding*/, 2));

c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 3;
//c.fill = GridBagConstraints.HORIZONTAL;
c.anchor = GridBagConstraints.NORTH;
c.weighty = 1;
panelDynamique.add(panelDispo, c);

c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 4;
c.fill = GridBagConstraints.HORIZONTAL;
panelDynamique.add(new JSeparator(), c);

for(Entry<String, String> entry : this.HMServ().entrySet()){

    JPanel tmp = new JPanel();
    tmp.setLayout(new GridLayout(3, 1));
    tmp.add(new JLabel(entry.getKey())); //1) Test, 2) Mitramail
    tmp.add(new JLabel("Version : " + entry.getValue())); //1) Version 1.5, 2) 1.0
    tmp.add(new JLabel(this.infoVersion(entry.getKey(), entry.getValue()))); //Disponible

    panelDispo.add(tmp);

}

任何人都知道如何让我的“绿色”GridLayout 填充红色 GridBagLayout 宽度并有 2 列来添加动态 GridLayout，如下所示：

1 | 2

3 | 4

5 | 6

7 | ...

?

感谢您的关注。

诊断上下文代码 sn-ps 有点困难，因为您的代码中可能发生了一些您没有共享的事情，这可能会影响结果

以后，请考虑提供一个runnable example 来证明您的问题。这不是代码转储，而是您正在做的事情的一个例子，它突出了您遇到的问题。这将减少混乱并获得更好的响应

话虽如此，它似乎对我有用......
