[Tkinter] Can´t create a class for frames

[deanhystad]

I don't understand the "Correction". It looks like *args and **kwargs are crossed out.

You want to pass *args and **kwargs as arguments to super().__init__(). This lets you pass arguments that are understood by Frame.

In this example I use **kwargs to set the background color for the frame. I also show you you can subclass classes that you make, not just tkinter classes. I wrote a custom class for each page I add to the notebook.

import tkinter as tk
import tkinter.ttk as ttk

class NotebookPage(tk.Frame):
    def __init__(self, parent, name, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        parent.add(self, text=name)

class Page1(NotebookPage):
    def __init__(self, parent, *args, **kwargs):
        super().__init__(parent, "Page 1", *args, **kwargs)
        tk.Label(self, text="This is page 1", bg=self["bg"]).pack(padx=10, pady=10)

class Page2(NotebookPage):
    def __init__(self, parent, *args, **kwargs):
        super().__init__(parent, "Page 2", *args, **kwargs)
        tk.Label(self, text="This is page 2", bg=self["bg"]).pack(padx=10, pady=10)

class MyWindow(tk.Tk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        notebook = ttk.Notebook(self)
        notebook.pack(padx=5, pady=5)
        Page1(notebook, bg="yellow")
        Page2(notebook, bg="light blue")

MyWindow().mainloop()
