具有 3 个 ScrollView 布局的 Kivy ScrollView - 尝试像 Excel 中那样创建冻结窗格
Kivy ScrollView with 3 ScrollView Layouts - Trying to create freeze pane like in Excel
我在 Python
中使用 Kivy 库
我正在尝试将 3 个滚动布局组合在一起。基本上，一个副列表、一个 header 视图和一个主要 body window。旁边的列表应该只上下滚动。 header 应该只左右滚动，主 window 可以在两个轴上滚动。我已经完成了这么多，但主要 window 中的信息将链接到 header 和辅助列表中的信息，因此让它们独立滚动是行不通的。
我的目标是当主 window 滚动时，x 和 y 滚动值被传递到侧边菜单和 header 以便它们都在适当的方向一起滚动.我通读了 github 上的滚动视图代码，只是无法弄清楚我可以使用哪些属性来使其工作。我在想我可以将卷轴从一种布局传递到另一种布局！也许太简单了！！！
或者，也许我需要从 GridLayout 开始？？
感谢任何意见

所以在 6 小时后我终于搞定了，感谢
这是我使用的代码，只是将相关的 scroll_x 和 scroll_y 值绑定到彼此的滚动框！！ PY 文件没有变化，只在 kv 文件中添加了几行！
这是更新后的 KV 文件
