如何在 kivy 的弹出 window 中发送数据或更改标签
how to send data or change label in popup window in kivy
我在这里尝试了很多关于我的问题的帖子，但没有一个对我有用。我确定我还不够好，无法理解它们。
我基本上想向弹出窗口 window 发送一个数据 table。
我用 ttk.treeview 做了同样的程序。这个 ttk.treeview 让我看到了一个很好的 table。但现在我想用 kivy 升级它。因此我选择了数据table。
我找不到任何其他选项来显示漂亮的数据 table，如 ttk.treeview。除了datatable还有什么建议吗？
当您 运行 这个 python 文件时，您将看到弹出屏幕。您单击“Dex”，然后它会打开一个弹出窗口 window。您将任何数据放在那里然后单击“计算”，然后我想将这些输入的计算结果显示到此 window.
的底部按钮 space 中
我在 calculate(self) 函数中放置了一个虚拟数据table。
你能帮我吗？我的问题行是 python 文件第 77 行。
非常感谢。
