Tkinter: multitab window

[deanhystad]

You need to write the pages using a common API. This can be as simple an init and a way to get the page and maybe the title.

Notobook module

import tkinter as tk
from tkinter import ttk

import page1
import page2

class Paper(tk.Tk):
    def __init__(self):
       super().__init__()
       self.title("Daily Paper")
       
       self.notebook = ttk.Notebook(self)
       self.notebook.pack(fill='both')
       self.add_page(page1.Page1)
       self.add_page(page2.Page2)
   
    def add_page(self, page_cls):
        page = page_cls(self.notebook)
        self.notebook.add(page.frame, text=page.title)
   
my_app = Paper()
my_app.mainloop()

Page module

import tkinter as tk

headlines = ('Covid Cured', 'Economy Rebounds', 'Global Warming Reversed', 'World Peace')
 
class Page1:
    def __init__(self, parent):
        self.title = 'Headlines'  # Tab title in notebook
        self.frame = tk.Frame(parent) # Tab conents
        for i, text in enumerate(headlines):
            story = tk.Label(self.frame, text=text)
            story.grid(row=i, column=0)

May as well have two pages:

import tkinter as tk

sports = ('Hockey', 'Baseball', 'Soccer', 'Football', 'Basketball')
 
class Page2:
    def __init__(self, parent):
        self.title = 'Sports'
        self.frame = tk.Frame(parent)
        for i, text in enumerate(sports):
            story = tk.Label(self.frame, text=text)
            story.grid(row=i, column=0)

The notebook will automatically resize to fit the largest page, and the main window automatically resizes to fit the notebook.

It should be pretty easy to automate filling the notebook with pages. You could put all the page modules in a folder and the notebook module would open scan the folder, import the page modules, and add the page. The contents of the pages themselves could be automated.
