具有GridBagLayout的JPanel中具有FlowLayout的JPanel无法正确锚定

Question

我正在为角色扮演游戏制作角色创建面板。它有一个JPanel使用GridBagLayout，其中一个JPanel使用FlowLayout。

最初，当我不使用FlowLayout时，它看起来像这样：

我需要在x轴上添加另一个组件。 weightx值将增加并变为偶数。这会使我所有的头衔都偏离中心，我不喜欢那样。我当时想我可以使用JPanel将我的某些组件放入FlowLayout内，或者将其包装在JScrollPane或类似的东西中：

不幸的是，使用JPanel的{​​{1}}并没有被使用网格网格布局的FlowLayout锚定。尽管已设置为锚点JPanel，但它还是转到了显示屏的侧面。

我的代码：

GridBagConstraints.BASELINE

其他：

• 我尝试做SSCCE。我不介意有人在没有颜色和字体的情况下运行我的代码！

JLabel clickNext = new JLabel("Continue"); clickNext.setForeground(stone); clickNext.setFont(titleFont); clickNext.setVisible(true); charScreen.add(clickNext, c); } } 用作“按钮”。 Mac的按钮图标真的很丑，所以我流氓了。上面的代码已修改为仅显示相关组件。在我的程序中，JLabel中添加了MouseListener。

<meta name="viewport" content="width=device-width,initial-scale=1"> 是没有意义的，因为namePanel.add(labelName, c);使用的是namePanel，将FlowLayout传递给它是没有意义的，因为它对GridBagLayoutConstraint毫无意义

FlowLayout有效地传递了“默认值” charScreen.add(namePanel);，这意味着GridBagLayoutConstraint会自行决定是否进行布局，这对您没有帮助。

也许您是说GridBagLayout，其中charScreen.add(namePanel, c);是您传递给c的约束

例如...

namePanel
