Question

嘿，我想要的是同一张图片在不同位置弹出4秒。此时，所有照片立即弹出。我试图将time.sleep添加到for循环中，但是所有照片立即以任何方式弹出。请尝试我的代码，并通过虚拟方式向我展示如何修复，因为我是python的新手。谢谢

from tkinter import *
from PIL import ImageTk, Image
from os import walk, getenv, system
from shutil import copyfile
import subprocess
import requests, subprocess, os, tempfile
import os
import tkinter.messagebox
import time


# This is the fuction that makes the original photo and is what root.after calls to later on in the code. 
def ShowAnotherWin(i):
    win = Toplevel()
    image = ImageTk.PhotoImage(Image.open('C:/Users/capture.PNG'))
    win.geometry(i)
    canvas =Canvas(win, width=420, height=560)
    canvas.create_image(0, 0, image= image, anchor=NW)
    canvas.pack()
    win.overrideredirect(1)
    win.mainloop() 




# This is the list it, it consists of different y and x interpects point and will be combined with the showanotherwin to makee a unique image pop up.

YourImageList = ['420x544+0+0',  
  time.sleep(1)
 '420x544+200+600',
  time.sleep(88)
 '420x544+1300+100',
 '420x544+1500+800',
 '420x544+900+500',
 '420x544+500+75',



]

# this code right here takes all the elements in the list and combines it with the showanotherwin. It then displays on screen.
root = Tk()
for i in YourImageList:
    root.after(0, lambda i=i: ShowAnotherWin(i))
    # time.sleep(1)>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> leads to all the photos poping up with the only, effect being the duration of the photos poping up. Please help!!

# this right here is just making another photo by itself dont worry about it.   
image = ImageTk.PhotoImage(Image.open('C:/Users/capture.PNG'))
root.geometry('420x544+750+200')
canvas = Canvas(root, width=420, height=560)
canvas.create_image(0, 0, image= image, anchor=NW)
canvas.pack()
root.overrideredirect(1)
root.mainloop()

Answer 1

您基本上将它们全部武装起来，在这里root.after( 0 ,...延迟0毫秒后出现。

for i in YourImageList:
    root.after(0, lambda i=i: ShowAnotherWin(i))

Answer 2

简单的方法是：

@ViewChild('firstTable') myTable: DatatableComponent;

另一种方法是在for i, x in enumerate(YourImageList): root.after(i*4000, lambda x=x: ShowAnotherWin(x))内部调用after()：

ShowAnotherWin()

我希望我的tkinter图像每4秒显示一次，而不是一次全部显示
