If the code is outside the function it provides the same image for all items in the treeview.Īt runtime I want to do is read the required image for example tupbomd and apply the appropriately rendered image to that particular line of the treeview. import tkinter as tk from tkinter import ttk root tk.Tk () class CbTreeview (ttk.Treeview): def init (self, masterNone, kw): kw.setdefault ('style', 'cb.Treeview') kw.setdefault ('show.

Print(( str(nbi)) + ' ' + tupbomd + ' ' + tupbomd + ' ' + tupbomd) are there some prerequisites for images on treeviews? tupbomi = The association with the term tree is due to programming practice: tree structures are a commonplace in program design.
