如何在GridbagLayout中对齐字段

我需要调整时间，使它看起来像这样：

到目前为止，我已经在这段代码中实现了它:(这是我的代码的简短版本）

我的问题是，在“输入时间：”的标签下面，我在那里放了一个空白标签。当我将JTextField放在那里时，我无法将其与上面的图片对齐，因为它的单元格与其上方的JLabel对齐。我尝试了gridwidth，gridheight（ - 用于向上和向下按钮），weightx，insets，并添加了空白JLabel（ - 占用线末端的空间）。所有这一切都失败了。我不知道我做错了什么或什么的。我也知道我不必打电话给setPreferredSize，但我必须这样做，因为我希望时间字段能够获得与上图相同的宽度。我不认为向上和向下按钮的对齐方式与图片中的一致，因为在GridBagLayout之间没有。好吧，我试图将时间字段的gridheight设置为2，结果仍然如此。有没有办法像图片一样对齐这些字段？

Answer 1

我认为您不知道GridBagLayout与Grid NxM一起使用，这意味着同一列中的所有组件都具有相同宽度的单元格，并且同一行中的所有组件都位于相同高度的单元格中。这只是一个网格。

问题很简单，你在0列中有一些组件：“输入日期：”标签，输入日期TextField ...所以最宽的组件决定了该列的大小。现在你要放一堆代表[14:00 Up / down]的文本字段，标签和按钮。你现在这样做的方法是首先放一个没有真正做任何事情的空标签（除了使用它的单元格），然后将所述组件放在第2,3,4列中......

然而，正如我所说，第0列非常宽，所以第1列开始于已经放在那里的所有部分的右边，所以这就是为什么所有这些组件都出现在“右边”，因为第0列非常宽

现在把它们放在合适的位置有2种选择。要么使上面的所有组件跨越多个列，那么您可以使用这些列在这些组件下放置所需的每个组件或创建包含组件的面板，然后将此面板放在“输入时间：”下的第0列中

在我看来，第二种方法更好，所以我去定义了timeInputPanel用我们想要的组件填充它，然后把它放在panel_4的第0列。现在因为timeInputPanel只是一个组件，它可以在列0内没有任何问题，即使它包含其他几个组件。

相关代码就是这样：

JPanel timeInputPanel = new JPanel(new FlowLayout(FlowLayout.LEADING));
timeInputPanel.add(text_33);
timeInputPanel.add(label_4);
timeInputPanel.add(text_4);
timeInputPanel.add(upDownPanel);

c.fill = GridBagConstraints.BOTH;
c.weightx = 1.0;
c.weighty = 1.0;
c.gridx = 0;
c.gridy = 15;
c.insets = new Insets(0, 10, 0, 0);
panel_4.add(timeInputPanel, c);

当然，您可能希望根据自己的喜好更改GridBagConstraints，唯一重要的是c.gridx = 0;和正确的gridy。

看起来像这样：
