java - Swing 组件之间的新线

Question

我已经尝试多次搜索如何多次格式化 java swing 元素，但我似乎找不到任何东西。我曾尝试学习网格袋布局，但它太复杂了。有人可以告诉我如何用 Swing 分隔摆动组件吗？谢谢！

spacer我用那个标签即兴创作了一点。我希望一些有经验的用户不会生气；）。但我希望这是你正在寻找的：

PS 使用的布局：MigLayout

您是否使用google 的netbeans或WindowBuilderPro等 GUI 编辑器进行 Eclipse 的尝试？使用这样的编辑器要容易得多，也是了解不同布局如何协同工作的好方法。希望这可以帮助。

我还发现了一种使用网格布局的更简单方法，它比 Mig 布局简单得多。抱歉，添麻烦了！

当 GridBag 感觉有点矫枉过正时，我会使用垂直方向的Box 。
