GridBagLayout + GridLayout的Java問題

Question

我在GridBagLayout中的GridLayout遇到問題。

我希望我的GridLayout適合GridBagLayout的寬度。

我說明了我要做什么：

但是這是我獲得的：

“測試版本：1.5，不負責任”是具有1列和3行的GridLayout。 “ Mitramail，1.0版，Disponible”是另一個具有1列和3行的GridLayout。 我試圖將它們添加到具有x行和2列的另一個GridLayout中。 因此通常它們應該彼此相鄰，但是它們是彼此相鄰的。

這是代碼：

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);

}

任何人都知道如何使我的“綠色” GridLayout填充紅色GridBagLayout寬度，並有2列添加如下所示的動態GridLayout：

1 | 2

3 | 4

5 | 6

7 | ...

？

感謝您的關注。

診斷上下文外代碼段有些困難，因為您的代碼中可能存在某些事情，您尚未共享，這可能會影響結果

將來，請考慮提供一個可運行的示例來演示您的問題。 這不是代碼轉儲，而是您正在執行的操作的一個示例，突出顯示了您所遇到的問題。 這將減少混亂並改善響應

話雖如此，它似乎對我有用...
