how to generate multiple buttons with a loop?

Question

I have programmed software that displays a "tuile".

Definition of a tuile:

A tuile is a Frame which contains a button which displays an image and an explanatory text.

I would like to display 3 tuiles with 3 different settings.

listes_icones = ["icone1.png","icone2.png","icone3.png"]
listes_relx = [".3",".4",".5"]
listes_text = ["SYSTEM", "USER", "GAME"]

for i in range(3):

    gen_img = PhotoImage(file=listes_icones[i])
    gen_cadre = Frame(home,width=100, height=100,bg=bg_root)
    gen_cadre.place(anchor="c", relx=listes_relx[i], rely=.5)

    gen_img_bouton = Button(gen_cadre, image=gen_img, relief="flat",bg=bg_root)
    gen_img_bouton.pack()

    gen_text = Label(gen_cadre, text=listes_text[i], bg=bg_root, fg=text_color,font="blocktastic 18")
    gen_text.pack()

I manage to display the text but not the button and the image, the variable is overwritten. How to solve this problem?

The problem that you are facing is like you said, the variable is overwritten in your loop. To solve this you need to keep track of your generated images. A simple solution is to store them in a list and get them in the next step. Here is an exampel:

import tkinter as tk
import PIL

listes_icones = ["icone1.png","icone2.png","icone3.png"]
gen_icons = []
listes_relx = [".3",".4",".5"]
listes_text = ["SYSTEM", "USER", "GAME"]

home = tk.Tk()



for i in range(3):
    gen_img = tk.PhotoImage(file=listes_icones[i])
    gen_icons.append(gen_img)
    gen_cadre = tk.Frame(home,width=100, height=100)
    gen_cadre.place(anchor="c", relx=listes_relx[i], rely=.5)

    gen_img_bouton = tk.Button(gen_cadre, image=gen_icons[i], relief="flat")
    gen_img_bouton.pack()

    gen_text = tk.Label(gen_cadre, text=listes_text[i], font="blocktastic 18")
    gen_text.pack()

home.mainloop()

Hello ! Can we add a command to each button generated ? gen_img_bouton.command(Myfunction) ? — IIX 61, Aug 06 '20 at 17:39
Yes we can!. Look into that link https://stackoverflow.com/questions/10865116/tkinter-creating-buttons-in-for-loop-passing-command-arguments — Thingamabobs, Aug 06 '20 at 17:42
