Java Mig布局：对齐不良

我的米格布局有问题。我已经开始重新创建JFrame的主JPanel，我在过去使用了绝对布局。起初一切顺利（第二幅图）。控制台面板（带有选项卡面板的框的一部分）对齐良好，但仍然是绝对布局。当我开始将单个JPanel的布局转换为Mig布局时，它看起来像第一张图像（没有左对齐）。同样的结果也适用于我将绝对布局更改为Mig布局的其他JPanel

[坏的] [好]

这是我的frame类的简化版本。这个结构看起来很奇怪，因为我试着尽量减少它。我还删除了控制台面板，因为我的问题 甚至出现带有MigLayout的默认JPanel

        contentScrollPane.setBorder(BorderFactory.createEmptyBorder());
        setContentPane(contentScrollPane);
}

private Border getTitleBorder(String title){
    return BorderFactory.createTitledBorder(null, title, TitledBorder.LEFT,       TitledBorder.TOP, new Font("null", Font.BOLD, 12), Color.BLUE);
}
 }

目标： 关键是，我希望控制台面板和绘图面板适合右面板，没有间隙（完美的边框对齐），根据右面板的增长和收缩行为进行扩展和收缩

编辑：我最近有个发现。如果我将Mig布局面板放置在JTabbedPane中，它就会工作。如果我将Mig布局面板放置在单独的JPanel中，它将不起作用。但我一点也不知道是怎么回事，为什么。

我认为问题在于您仍然使用的

BoxLayout

。我添加了更多的布局，现在看起来就像你想要的

不知道（没有足够的信息）只是一些一般性的评论：a）不要使用子面板b）不要使用有标题的边框c）不要硬编码像素我认为没有足够的信息得出结论。可以帮助您的一件简单的事情是将“debug 1000”添加到布局约束中，这将显示网格和组件边界。*我将“debug 1000”添加到主面板和控制台面板中。右面板（=框）具有良好的对齐效果，与预期的一样，其左边框与选项卡面板边框重合。但是，控制台面板的左边框与右面板的左边框不重合。
