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

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()
