为什么 tkinter 小部件出现在错误的窗口上？

Question

我已经为这个错误苦苦挣扎了几个星期。菜单预计会根据单击的按钮打开一个新窗口，它确实如此。当 ttk.Treview 对象（或表格）预计会出现在新窗口中但它一直出现在菜单一上时，就会出现问题。 我试过检查亲子关系，但一切似乎都很好。有人能告诉我为什么会这样吗？

第二个主要用于独立运行每个窗口并且它有效。但是当通过菜单打开时，它一直在窃听。执行更改时，其他方法会更新表，但我认为这可能无关。

#updating the visual table (R in CRUD)
def get_rows(self):
    #Clear the zone before displaying
    records = self.tree.get_children()
    for element in records:
        self.tree.delete(element)

    query = f"Select * from {self.table_name}"
    db_rows = self.run_query(query)

    for row in db_rows:
        self.tree.insert('', 0, text=row[1], values=row)
