我一直试图在 Gtk 中使用数据库中的数据创建分层 TreeView，但一直没有成功（创建具有未知数据集长度的分层 Gtk.TreeStore）。我发现在 TKinter 中我几乎可以做我想做的事情，但是存在一些问题。

1. 如果一个节点具有与另一个节点相同的值，Python 会抛出以下错误：

    add_node(k, v, x)
  File "/home/bigbird/tvTk3.py", line 10, in add_node
    tree.insert(k, 1, i, text=i,values=[myList2[x][1]])
  File "/usr/lib/python3.10/tkinter/ttk.py", line 1361, in insert
    res = self.tk.call(self._w, "insert", parent, index,
_tkinter.TclError: Item Electric already exists

有可能存在同名的节点吗？我应该做哪些更改来避免这种情况？

1. 我希望将与每个值关联的数字插入到树视图的第 1 列中。但是行 values=[myList[x][1]] 不会随着每个新节点而改变。如何获取行中的关联数字？

有人能帮我实现这个吗？非常感谢。
