java - 如何对齐 GridbagLayout 中的字段

Question

我需要对齐时间，使其看起来像这样:

到目前为止，我已经在这段代码中实现了它:(这是我的代码的一个简短版本)

我的问题是在“输入时间:”的标签下方我放了一个空白标签。当我将 JTextField 放在那里时，我无法像上图那样对齐它，因为它的单元格正与它上面的 JLabel 对齐。我已经尝试了 gridwidth、gridheight(- 用于向上和向下按钮)、weightx、insets 和添加一个空白 JLabel(- 以占据行尾的空间)。而这一切都失败了。我不知道我做错了什么。我也知道我不必调用 setPreferredSize 但我必须调用，因为我希望时间字段获得与上图相同的宽度。我认为向上和向下按钮的对齐方式不会像图片中那样，因为在 GridBagLayout 中没有中间位置。好吧，我已经尝试将时间字段的 gridheight 设置为 2，结果仍然是那样。有没有办法像图片中那样对齐这些字段？

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。它只是一个网格。

问题很简单，第 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。现在你想要放置一堆文本字段、标签和按钮来表示 [14:00 Up/down]。您现在的做法是首先放置一个实际上不执行任何操作(除了使用其单元格)的空标签，然后将所述组件放入第 2、3、4 列...

然而，正如我所说，第 0 列非常宽，因此第 1+ 列从已经放置在那里的所有内容的右侧开始，这就是为什么所有这些组件都出现在“右侧”的原因，因为第 0 列非常宽.

现在要将它们放在正确的位置，有 2 个选项。要么让上面的所有这些组件跨越几列，这样您就可以使用这些列将您需要的所有内容放在这些组件下，或者创建一个包含这些组件的面板，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，所以我定义了一个 timeInputPanel，用我们想要的组件填充它，然后将它放在 panel_4 的第 0 列中>。现在因为 timeInputPanel 只是 1 个组件，它可以毫无问题地驻留在列 0 内，即使它包含几个其他组件也是如此。

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; 和适当的 gridy。

看起来像这样:
