错误:

如下所述，winfo_parent() 是获取父母姓名的方法.

Mentions as below, winfo_parent() is a method to get parent's name.

您得到的错误意味着 event.widget 没有名为 _nametowidget 的方法.所以你不能把它作为一个函数来调用.

The error you get means that event.widget doesn't has the method named _nametowidget. So you could not call that as a function.

您可以尝试以下代码来获取父级.

You may try codes below to get the parent.

parent = event.widget.winfo_parent()
from Tkinter import Widget
Widget._nametowidget(parent)
