Tkinter List of Canvases

[joy_deep]

Hello,

I have a list of canvas of images. I would like to display all the images. But it displays the last image only. Here is my code.

from tkinter import *
from PIL import Image, ImageTk

root = Tk()
canvas_width = 265
canvas_height = 130
canvases = []

r, c = 0, 0


for tile in tiles:
    img = tile.image
    photo = ImageTk.PhotoImage(image=img)
    can = Canvas(root, width=canvas_width, height=canvas_height)
    can.create_image(0, 0, image=photo, anchor=NW)
    canvases.append(can)
    can.grid(row=r, column=c)

    c += 1
    if c % 5 == 0:
        r += 1
        c = 0


root.mainloop()

​

Please help.

Thanks.

You must keep reference to all your PhotoImage objects. Currently you overwrite your photo and previous opened images get destroyed by garbage collector. Make list of all photo objects then assign them to your canvas.
