Tkinter & Canvas

[Peter_Emp1]

Hello, everyone!

I'm trying to create several tk.Canvas() for each ttk.Frame() to display different figures and images on my TabWidget (ttk.Notebook).
But When i try to create two instance of tk.Canvas() on two different ttk.Frame(), NOTHING displays at all!!!

You can use any png. They don't displays!

I tried it to do smth like this:

import tkinter as tk
from tkinter import ttk

class Guess():
    def __init__(self, parent, canvas):
        # Creating Frame
        # super().__init__(parent)
        self.window = parent

        # Creating Canvas for frame Guess:
        # self.canvas = tk.Canvas(self.window, width=1600, height=1000)
        self.canvas = canvas
        self.canvas.pack()

        ###-------------------- Using canvas here.......
        # Add image file
        bg = tk.PhotoImage(file="background1.png")
        # Display image
        self.canvas.create_image(0, 0, image=bg, anchor="nw")


class Full():
    def __init__(self, parent, canvas):
        # Creating Frame
        # super().__init__(parent)
        self.window = parent

        # Creating Canvas for frame Full:
        # self.canvas = tk.Canvas(self.window, width=1600, height=1000)
        self.canvas = canvas
        self.canvas.pack()

        ###-------------------- Using canvas here.......
        # Add image file
        bg = tk.PhotoImage(file="background2.png")
        # Display image
        self.canvas.create_image(0, 0, image=bg, anchor="nw")


class Main:
    def __init__(self):
        self.window = tk.Tk()
        self.window.title("Analysis")
        self.window.geometry('1600x1000')

        # create a notebook
        notebook = ttk.Notebook(self.window)

        # Create and add tabs
        frame_guess = ttk.Frame(notebook, width=1600, height=1000)
        frame_note_full = ttk.Frame(notebook, width=1600, height=1000)
        frame_note_shorted = ttk.Frame(notebook, width=1600, height=1000)

        # Create Canvas for frames
        frame_guess_canvas = tk.Canvas(frame_guess, width=1600, height=1000)
        frame_note_canvas = tk.Canvas(frame_note_full, width=1600, height=1000)

        # Add ttk.Frame to ttk.Notebook
        notebook.add(frame_guess, text="Guess")
        notebook.add(frame_note_full, text="Note_Full")
        notebook.add(frame_note_shorted, text="Note_Shorted")

        Guess(frame_guess, frame_guess_canvas)
        Full(frame_note_full, frame_note_canvas)

        notebook.pack(padx=5, pady=5, fill="both", expand=True)

        # frame_guess.pack(fill="both", expand=True)
        # frame_note_full.pack(fill="both", expand=True)
        # frame_note_shorted.pack(fill="both", expand=True)
        # tab1 = ttk.Frame(notebook, width=1600, height=800)

        # Connecting Destructor
        self.window.protocol('WM_DELETE_WINDOW', self.__dell__)

        # Add image file
        # bg = tk.PhotoImage(file="background.png")
        # Display image
        # self.canvas.create_image(0, 0, image=bg, anchor="nw")

        # Launch mainwindow
        self.window.mainloop()

    def __dell__(self):
        # Destroy mainwindow
        self.window.destroy()


Main()
