Tkinter, Toplevel blank image

Here is a very basic example of how to switch from one content to another.

import tkinter as tk # Function to switch the contents of the window def frame_switch(): # winfo_ismapped indicates if a widget is "packed" if main_frame.winfo_ismapped(): window.title('Second frame') # Unpacking the frame and packing the other main_frame.pack_forget() second_frame.pack() else: window.title('Main Frame') second_frame.pack_forget() main_frame.pack() window = tk.Tk() window.geometry('400x200') window.title('Main Frame') # Frame visible at launch main_frame = tk.Frame(window) main_frame.pack() info_label = tk.Label(main_frame, text='info blabla', bg='blue', fg='white') info_label.pack() switch_button = tk.Button(main_frame, text='To blabla', command=frame_switch) switch_button.pack() # Frame invisible at launch and its content second_frame = tk.Frame(window) blabla_text = tk.Text(second_frame, width=50, height=7) blabla_text.pack() blabla_text.insert(0.0, 'blabla\n' * 5) back_button = tk.Button(second_frame, text='Go Back', command=frame_switch) back_button.pack() window.mainloop()

If you understand the principle, you will have no trouble adapting it to your needs.

Good luck.

Hello, we need to create an easily reproducible example; we don't have your images, and the window size is quite large.

Also, why use a canvas to place your widgets?

Now, if we comment out all the parts related to the images, it "works".

from tkinter import * def open_toplevel(): global choix_on if choix_on == True: choix_on = False else: choix_on = True if choix_on == False: # win.withdraw() DG = Toplevel(win) width = 800 height = 600 canvas = Canvas(DG, width=width, height=height) canvas.pack() # fight = PhotoImage(file="fight.png") # fight.config(width=width, height=height) # canvas.create_image(0, 0, image=fight, anchor="se") atk = Button(DG, text="Attack", bg="red", fg="orange") inv_button = Button(DG, text="Inventory", bg="blue", fg="purple") run_button = Button(DG, text="Run", bg="green", fg="yellow") canvas.create_window(200,400, window=atk) canvas.create_window(200, 425, window=inv_button) canvas.create_window(200, 450, window=run_button) win = Tk() # win.geometry("1920x1080") choix_on = True width = 800 height = 600 # right = PhotoImage(file="flècheDroiteS.png") # right.config(width="174", height="100") # left = PhotoImage(file="flecheGaucheS.png") # left.config(width="174", height="100") # choice = PhotoImage(file="choix.png") canva = Canvas(win, width=width, height=height) # canva.create_image(width, height, image=choice,anchor="se") label_start = Label(win, text="What would you like to do?", font=("Comic Sans MS", 20, "bold"), bg="#5db6ce", fg="white") canva.create_window(200, 200, window=label_start) canva.pack() RightArrow = Button(win,text='D', command=open_toplevel) # RightArrow.config(image=right) RightArrow.pack() canva.create_window(200, 400, window=RightArrow) LeftArrow = Button(win,text='G', command=open_toplevel) # LeftArrow.config(image=left) LeftArrow.pack() canva.create_window(300, 400, window=LeftArrow) win.mainloop()

What you're trying to do is modify the content of the main window, right?

In that case, you need to assign each content to different frames, and depending on what you want to display, pack and unpack these frames.

thank you very much now I just have to watch a good hour of how to use frames????

fail the "???"
