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......

以上这篇在python tkinter中Canvas实现进度条显示的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
