GridBagLayout + GridLayout的Java问题

我在GridBagLayout中遇到GridLayout问题。

我希望我的GridLayout符合GridBagLayout的宽度。

我举例说明了我想要做的事情:

Result expected

但这是我获得的:

Result obtained

"测试,版本:1.5,Disponible"是一个包含1列和3行的GridLayout。 " Mitramail,1.0版,Disponible"是另一个GridLayout,包含1列和3行。 我试图在另一个带有x行和2列的GridLayout中添加它们。通常它们应该彼此相邻,但它们是一个在另一个之下。

以下是代码:

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);

}

任何人都知道如何制作我的&#34; Green&#34; GridLayout填充Red GridBagLayout宽度并有2列添加动态GridLayout,就像这个架构一样:

1 | 2

3 | 4

5 | 6

7 | ...

感谢您的关注。

有点难以诊断脱离上下文的代码段,因为代码中可能会发生一些您未共享的内容,这可能会影响结果

将来,请考虑提供一个展示您问题的runnable example。这不是代码转储,而是您正在做的事情的一个示例,它突出了您遇到的问题。这将减少混淆和更好的响应

话虽如此,它似乎对我有用......
