Question

我正在使用python开发的一个小程序旨在按一定顺序显示一系列图像和音频片段。我可以在同一窗口中显示两个图像，一个可以按预期覆盖另一个图像，但是我正在寻找一种方法，可以使第二个图像在一定时间（30秒）后而不是尽快显示在程序运行时。不过，我似乎无法使第二张名为mutableMapOf()的图像与程序的其余部分分开运行。

要尝试解决此问题，我加入了textBox.jpg函数，但这只是延迟了整个代码的启动。

sleep()

我希望在程序运行了大约30秒并且已经显示了另一个图像之后调用第二个图像from tkinter import * from tkinter import ttk from PIL import Image, ImageTk import time # Title/Main window = Tk() window.title("Just Monika") window.configure(background="black") # control window size to make full-screen width_value=window.winfo_screenwidth() height_value=window.winfo_screenheight() window.geometry("%dx%d+0+0" % (width_value, height_value)) # Monika photo # this block will allow the image to resize to fit the window's size # indefinitely def resize_image(event): new_width = event.width new_height = event.height image = copy_of_image.resize((new_width, new_height)) photo = ImageTk.PhotoImage(image) label.config(image = photo) label.image = photo #avoid garbage collection monika = Image.open("C:\\Python Programs\\Just Monika\\Images\\justMonika.png") copy_of_image = monika.copy() photo = ImageTk.PhotoImage(monika) label = ttk.Label(window, image = photo) label.bind('<Configure>', resize_image) label.pack(fill=BOTH, expand=YES) # text box image textBox = Image.open("C:\\Python Programs\\Just Monika\\Images\\textBox.jpg") tkTextBox = ImageTk.PhotoImage(textBox) panel1 = Label(window, image = tkTextBox) panel1.place(x=675, y=300) time.sleep(30)。

按照@Masoud的建议，您可以使用通用窗口小部件after()方法来安排在指定的时间延迟后调用的函数：

from tkinter import *
from tkinter import ttk
from PIL import Image, ImageTk


PATH_IMAGE1 = 'justMonika.png'
PATH_IMAGE2 = 'textBox.png'
DELAY = 5000  # In milliseconds

# Title/Main
window = Tk()
window.title("Just Monika")
window.configure(background="black")

# control window size to make full-screen
width_value=window.winfo_screenwidth()
height_value=window.winfo_screenheight()
window.geometry("%dx%d+0+0" % (width_value, height_value))


# Monika photo
# this block will allow the image to resize to fit the window's size
# indefinitely
def resize_image(event):
    new_width = event.width
    new_height = event.height
    image = copy_of_image.resize((new_width, new_height))
    photo = ImageTk.PhotoImage(image)
    label.config(image = photo)
    label.image = photo #avoid garbage collection

def display_2nd_image():
    global panel1

    # text box image
    textBox = Image.open(PATH_IMAGE2)
    tkTextBox = ImageTk.PhotoImage(textBox)
    panel1 = Label(window, image=tkTextBox)
    panel1.place(x=675, y=300)
    panel1.image = tkTextBox #avoid garbage collection

monika = Image.open(PATH_IMAGE1)
copy_of_image = monika.copy()
photo = ImageTk.PhotoImage(monika)
label = ttk.Label(window, image=photo)
label.bind('<Configure>', resize_image)
label.pack(fill=BOTH, expand=YES)

window.after(DELAY, display_2nd_image)
window.mainloop()

有没有办法在单个图像上实现时间延迟？
