我正在尝试设置具有三个拆分窗格的 UI。前两个是垂直窗格，位于屏幕的左侧和右侧。每个拆分的一侧都有一个标题窗格。用户可以从这些窗格中选择项目以包含在中央窗格的字段中。底部还有一个与此问题无关的水平窗格。
用户可以通过拖动垂直分隔线或单击相关的切换按钮（电影、书籍等）来打开这些侧窗格以显示该窗格。
我遇到的问题是我想让它拖动一个垂直分隔线不会移动另一个。但是，由于在不将一个垂直拆分窗格放入另一个垂直窗格的情况下，我无法找到一种方法来设置它，因此这总是会导致移动其中一个分隔线同时移动另一个分隔线的情况。例如，在以下代码的情况下，移动左侧（电影）拆分窗格的垂直分隔线会移动右侧垂直分隔线。
有人能帮忙吗？
