# Progress bar widget

普通模式

# importing tkinter module 
from tkinter import * from tkinter.ttk import *

# creating tkinter window 
root = Tk() 

# Progress bar widget 
progress = Progressbar(root, orient = HORIZONTAL, 
			length = 100, mode = 'determinate') 

# Function responsible for the updation 
# of the progress bar value 
def bar(): 
	import time 
	progress['value'] = 20
	root.update_idletasks() 
	time.sleep(1) 

	progress['value'] = 40
	root.update_idletasks() 
	time.sleep(1) 

	progress['value'] = 50
	root.update_idletasks() 
	time.sleep(1) 

	progress['value'] = 60
	root.update_idletasks() 
	time.sleep(1) 

	progress['value'] = 80
	root.update_idletasks() 
	time.sleep(1) 
	progress['value'] = 100

progress.pack(pady = 10) 

# This button will initialize 
# the progress bar 
Button(root, text = 'Start', command = bar).pack(pady = 10) 

# infinite loop 
mainloop()

来回走不确定模式
