Question

我希望在堆叠的tkinter框架中连续显示两张图像，就像幻灯片一样。我听说，我可以用后方法做到这一点，但我该如何使用这种方法呢？对不起，如果我的英语不好。感谢。

不确定要将幻灯片添加到代码的位置，所以这里是一个简单的Tkinter GUI的最小工作示例，使用after到cycle尽管所有当前目录中的图像found。

from Tkinter import Tk, PhotoImage, Label
from glob import glob
from itertools import cycle

# this method calls itself again after 1000 milliseconds
def show_next():
    image.configure(file=next(images))
    root.after(1000, show_next)

# cycle though gif images found in working directory
images = cycle(glob("*.gif"))

# build minimal test GUI
root = Tk()
image = PhotoImage()
Label(root, image=image).pack()

# start slide show and GUI main loop
show_next()
root.mainloop()

Python使用after-method显示两个图像
