Python图形界面 Tkinter入门2

2.1图标

from tkinter import *

root = Tk()
root.title('显示自定义的ico图标')

# 应用窗口图标
root.iconbitmap('./ico.ico')

# 应用图标
# pip install pillow            图形库
from PIL import Image,ImageTk

my_img = ImageTk.PhotoImage(Image.open('ico.png'))
my_lable = Label(image=my_img)
my_lable.pack()

root.mainloop()

2.2简易图片查看器

# 应用窗口图标
root.iconbitmap('./ico.ico')

img3 = ImageTk.PhotoImage(Image.open('./jpg/3.jpg'))
img4 = ImageTk.PhotoImage(Image.open('./jpg/4.jpg'))
img5 = ImageTk.PhotoImage(Image.open('./jpg/5.jpg'))
img_list = [img1,img2,img3,img4,img5]


# 图片-显示
