限制在水平JScrollPane中的垂直JScrollPane中的JText区域中的组件大小
如何将水平滚动窗格中组件的垂直尺寸限制为滚动窗格的垂直尺寸？
GUI应该总是这样：
这是滚动水平滚动条后得到的结果：
相关代码段：创建框架，添加传感器列。也是在早些时候用BoxLayout尝试过这个问题。

**********这是主要的想法，丰富的细节和可运行的代码如果它有帮助**********
背景：我正在为引擎测试系统制作GUI。我在带有水平滚动条的JScrollPane中有一个带GridBagLayout的JPanel。在面板的每一列中，都有一个标题，文本区域，其中滚动窗格包含一列传感器数据，还有一个复选框，询问用户是否要导出该列数据。
意图：当用户加载文件时，它将从引擎日志中读取数据，将每个传感器分离到JPanel中的单独列，并在按下导出按钮时导出任何已检查的列。
什么工作：所有后端文件处理/分离都有效。
问题：加载文件并移动水平滚动条后，文本区域会垂直变大并延伸到水平JScrollPane下方。
我已尝试使用GridBagLayout和BoxLayout来解决此问题。盒子布局首先看起来正确，但在水平滚动时显示相同的有害行为。
GridBagLayout也总是尝试将JTextArea添加到顶行。不知道为什么。
我考虑在JTextAreas上使用setMaximumSize（），但是如果用户调整整个窗口的大小，这可能会使它们太小（这就是我无论如何都要打扰布局管理器的全部原因。否则，对于这个小的我刚刚使用绝对布局的程序）

* Each file has a different set of sensors
* The program puts each sensor in a separate column with a check box beneath it
* If the user leaves the box checked, that column is written to a CSV file the user exports

看太多代码看看你在做什么。当你提出问题时，你应该发布一个简单的代码来证明这个问题。有关详细信息，请参阅SSCCE。
如何将水平滚动窗格中组件的垂直尺寸限制为滚动窗格的垂直尺寸？
您添加到滚动窗格的面板需要实现Scrollable界面。特别是，您需要使用getScrollableTracksViewportHeight()方法返回true。
为了节省您自己实现整个界面，您可能需要查看Scrollable Panel。此类为您实现这些方法，您只需在类上设置属性即可获得所需的结果。听起来像你需要使用FIT属性作为可滚动高度。
