Nested Class factory with tkinter

Question

I\'m trying to build a script for import in my future projects. That Script should create some tk.Frames in a tk.Frame and let me edit the created ones in a main

One solution to this problem, I think, as I don't fully understand your question, but this here was my solution:

import tkinter as tk
from tkinter import Frame,Button

class BaseClass(tk.Frame):
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        self.master = master
        self.pack()


class Holder_frame(tk.Frame):
    def __init__(self, master, frames=2):
        tk.Frame.__init__(self, master)
        self.master = master
        self.frame_names = []
        for i in range(frames):
            Holder_frame.create_frames("F"+str(i+1), self)

    @classmethod
    def create_frames(cls, name, master):
        setattr(cls, name, tk.Frame(master))

if __name__ == "__main__":
    root = tk.Tk()
    def raise1():
        print(type(Holder_frame.F1))
    def raise2():
        print(type(Holder_frame.F2))

    holder=Holder_frame(root,frames=2)
    holder.grid(row=1,column=0)
    b1 = tk.Button(root, text='1', command=raise1)
    b1.grid(row=0,column=0)
    b2 = tk.Button(root, text='2', command=raise2)
    b2.grid(row=0,column=1)
    print(Holder_frame.__dict__.items())

    root.mainloop()

The use of setattr allows one to add variables to the class, just like if you were to type a function into the code. This allows you to access frames from outside the class as somewhat of a "global variable"

I used a file to test if it work outside as an imported module too:

# main.py
from nested_class import Holder_frame
import tkinter as tk

root = tk.Tk()
holder=Holder_frame(root,frames=1000)
holder.grid(row=1,column=0)
print(Holder_frame.__dict__.items())

root.mainloop()

I hope this answers your question,

EDIT:

After thinking there is, what I think, to be a cleaner system for what you want. With the code from this post one can see that your my written system could be replaced by a ttk.Notebook, and by removing the top bar by using style.layout('TNotebook.Tab', []), one can see that you would get a frame widget that could have frame widgets inside of it:

import tkinter as tk
import tkinter.ttk as ttk

class multiframe_example:
    def __init__(self, master):
        self.master = master

        style = ttk.Style()
        style.layout('TNotebook.Tab', [])   
        notebook = ttk.Notebook(self.master)
        notebook.grid(row=0, column=0)

        self.master.grid_rowconfigure(0, weight=1)
        self.master.grid_columnconfigure(0, weight=1)

        tab1 = tk.Frame(self.master,  width=500, height=500, background="green")
        tab2 = tk.Frame(self.master,  width=500, height=500)
        tab3 = tk.Frame(self.master,  width=500, height=500)


        notebook.add(tab1)
        notebook.add(tab2)
        notebook.add(tab3)

        notebook.select(0) # select tab 1
        notebook.select(1) # select tab 2
        notebook.select(2) # select tab 3

def main():
    root = tk.Tk()
    root.geometry("500x500")
    multiframe_example(root)
    root.mainloop()

if __name__ == '__main__':
    main()

Hope this code can support you and does as you would like!
