Question

How to clear a listbox when a button is clicked to re-populate it? The code below is giving me an error.

code:

self.listNodes.delete(0,END)

error:

NameError: name 'END' is not defined

Answer 1

Depending on how you imported tkinter you may have to put end in quotations Try:

  self.listNodes.delete(0,'end')

you can also use:

self.listNodes.delete(0,tk.END)

Answer 2

Replace:

self.listNodes.delete(0,END)

with:

self.listNodes.delete('0','end')

END is a variable of tkinter module, which suggests either a wildcard(from tkinter import *) import or from tkinter import END was supposed to be used.

Answer 3

You can use this is you imported tkinter as:

import tkinter as tk

self.listnodes.delete(0, tk.END)

Or you can do:

from tkinter import *

self.listnodes.delete(0, END)

Answer 4

Destruction is the best way to delete something.

self.listNode.destroy()

and then add Your data again to your ListBox.
