Tkinter - 使用 for 循环显示多个图像

Question

我正在尝试向 window 显示多张图片（作为标签），但只显示最后一张图片

from tkinter import *
from PIL import ImageTk, Image

root = Tk()

f = open("data/itemIDsList.txt")
ids = []
for line in f:
    line = line.rstrip("\n")
    ids.append(line)
f.close()

for i in range(10):
    img = ImageTk.PhotoImage(Image.open(f"website/images/{ids[i]}.png"))
    Label(root, image=img, width=60, height=80).grid()

root.mainloop()

Answer 1

每次在循环中重新赋值img，上一张图片的数据都会被破坏，无法再显示。要解决此问题，请将图像添加到列表以永久存储它们：

from tkinter import *
from PIL import ImageTk, Image

root = Tk()

f = open("data/itemIDsList.txt")
ids = []
for line in f:
    line = line.rstrip("\n")
    ids.append(line)
f.close()

imgs = []
for i in range(10):
    imgs.append(ImageTk.PhotoImage(Image.open(f"website/images/{ids[i]}.png")))
    Label(root, image=imgs[-1], width=60, height=80).grid()

root.mainloop()
