I am trying to create a simple open-sourced project for tagging Japanese Audiobooks with metadata from Audible Japan. I have a working script that grabs the title, author, and narrators, and I am trying to populate Tkinter's tree with that data. The problem arose when I tried doing it the OOP methodology, and broke everything up into different classes and functions.
import tkinter as tk
from tkinter import *
from tkinter import ttk

from bs4 import BeautifulSoup
class ResultFrame(ttk.Frame):
def __init__(self, container):
super().__init__(container)
# field options
options = {'padx': 10, 'pady': 10}
# result label frame
self.result_label = ttk.LabelFrame(self, text='Results')
self.result_label.grid(row=1, column=0, sticky=tk.W, **options)
# result tree
self.tree = ttk.Treeview(self.result_label)
self.tree['columns'] = ("Title", "Author", "Narrator", "Published")
self.tree.column("#0", width=0, stretch=NO) # hide the first autogenerated column
self.tree.column("Title", anchor=W)
self.tree.column("Author", anchor=W)
self.tree.column("Narrator", anchor=W)
self.tree.column("Published", anchor=W)
# result tree headings
self.tree.heading('#0', text='') # hide the first autogenerated column
self.tree.heading('Title', text='Title', anchor=W)
self.tree.heading('Author', text='Author', anchor=W)
self.tree.heading('Narrator', text='Narrator', anchor=W)
self.tree.heading('Published', text='Published', anchor=W)
self.tree.pack()
self.grid(padx=10, pady=10, sticky=tk.NSEW)
def populate_tree(self, data):
count = 0
for book in data.items():
self.tree.insert(
parent='', index='end', iid=count, text='',
values=(
book[0], book[1]['authors'], book[1]['narrators'], 'not implemented'
)
)
count = 1
class SearchFrame(ttk.Frame):

super().__init__(container)
self.audiobooks = {}
# field options

self.search = tk.StringVar()

temp_authors = []
temp_narrators = []
# build the url

query = self.search_entry.get()
# request the page

soup = BeautifulSoup(page.content, "html.parser")
# grab only the content that we need

def __init__(self):
super().__init__()

ResultFrame(app)

From my understanding reading this answer: https://stackoverflow.com/a/41513358, I would essentially have to make ResultFrame inherit from SearchFrame, so it would be ResultFrame(SearchFrame) instead of ResultFrame(ttk.Frame). But the issue is that both of my classes are inheriting from ttk.Frame, so I am unsure how to proceed.
To summarize my question, in my SearchFrame class, the function called search_audible scraped information from Audible. I would like to send that scrapped information to ResultFrame's populate_tree() so that it can show the results conveniently.
If possible, I would prefer to have the two Frames into separated classes, because it helps organize and manage the code in my opinion.

In order to do that SearchFrame needs to be aware of ResultFrame. You can do that by:
class SearchFrame(ttk.Frame):
def __init__(self, container,reciever):
super().__init__(container)
self.reciever = reciever
Through that reference you can target this object by:
self.reciever.populate_tree(self, data=self.audiobooks)
since you need a reference to that object you need to swap the order of construction to have a reference you can pass:
res = ResultFrame(app)
ser = SearchFrame(app,res)
Hint
class App(tk.Tk):
def __init__(self):
super().__init__()
self.res = ResultFrame(self)
self.ser = SearchFrame(self,self.res)
self.title('Audiobook Tagger')
if __name__ == '__main__':
app = App()
app.mainloop()
