I am trying to get the parent of a widget then get the parent of that widget. But Everytime I try to I get a error.
Error:
AttributeError: 'str' object has no attribute '_nametowidget'
Why is it giving me that error. Can someone explain to me why I am getting this error and help me to fix it?
Code:
parent = event.widget.winfo_parent()
parentName = event.widget._nametowidget(parent)
frameParent = parentName.winfo_parent()
frameParentName = frameParent._nametowidget(frameParent)
http://effbot.org/tkinterbook/widget.htm
Mentions as below, winfo_parent() is a method to get parent's name.
The error you get means that event.widget doesn't has the method named _nametowidget. So you could not call that as a function.
You may try codes below to get the parent.
parent = event.widget.winfo_parent()
from Tkinter import Widget
Widget._nametowidget(parent)
grandparent = event.widget.master.master
See the answer here.
Your second call to _nametowidget() is different than your first. Your fourth line is bad, since you're basing the call to _nametowidget() on a string (frameParent) instead of on a widget (parentName). This is partly because your naming convention of "widget" and "widgetName" is reversed...
frameParentName = frameParent._nametowidget(frameParent)
^^^^^^^^^^^ -- this is the name string. you need a widget
I would slightly rewrite your code as follows:
parentName = event.widget.winfo_parent()
parent = event.widget._nametowidget(parentName) #event.widget is your widget
frameParentName = parent.winfo_parent()
frameParent = parent._nametowidget(frameParentName) #parent is your widget
