python tkinter进度条_在python tkinter中Canvas实现进度条显示的方法

如下所示：

from tkinter import *

import time

#更新进度条函数

def change_schedule(now_schedule,all_schedule):

canvas.coords(fill_rec, (5, 5, 6 + (now_schedule/all_schedule)*100, 25))

root.update()

x.set(str(round(now_schedule/all_schedule*100,2)) + '%')

if round(now_schedule/all_schedule*100,2) == 100.00:

x.set("完成")

root = Tk()

#创建画布

frame = Frame(root).grid(row = 0,column = 0)#使用时将框架根据情况选择新的位置

canvas = Canvas(frame,width = 120,height = 30,bg = "white")

canvas.grid(row = 0,column = 0)

x = StringVar()

#进度条以及完成程度

out_rec = canvas.create_rectangle(5,5,105,25,outline = "blue",width = 1)

fill_rec = canvas.create_rectangle(5,5,5,25,outline = "",width = 0,fill = "blue")

Label(frame,textvariable = x).grid(row = 0,column = 1)

'''

使用时直接调用函数change_schedule(now_schedule,all_schedule)

下面就模拟一下....

'''

for i in range(100):

time.sleep(0.1)

change_schedule(i,99)

mainloop()

实现的甚是粗糙......
