这篇文章主要介绍了python实现的简单窗口倒计时界面,实例分析了Python基于Tkinter操作windows窗口界面的相关技巧,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了python实现的简单窗口倒计时界面。分享给大家供大家参考。具体分析如下：

下面的代码通过Tkinter制作windows窗口界面，然后时间了一个简单的倒计时功能，代码可以直接运行

									# Countdown using Tkinter 

									from Tkinter import *

									import time

									import tkMessageBox

									class App:

									 def __init__(self,master):

									  frame = Frame(master)

									  frame.pack()

									  self.entryWidget = Entry(frame)

									  self.entryWidget["width"] = 15

									  self.entryWidget.pack(side=LEFT)

									  self.hi_there = Button(frame,text="Start",command=self.start)

									  self.hi_there.pack(side=LEFT)

									  self.button = Button(frame,text="QUIT",fg="red",command=frame.quit)

									  self.button.pack(side=LEFT)

									 def start(self):

									  text = self.entryWidget.get().strip()

									  if text != "":

									   num = int(text)

									   self.countDown(num)

									 def countDown(self,seconds):

									  lbl1.config(bg='yellow')

									  lbl1.config(height=3, font=('times',20,'bold'))

									  for k in range(seconds, 0, -1):

									   lbl1["text"] = k

									   root.update()

									   time.sleep(1)

									  lbl1.config(bg='red')

									  lbl1.config(fg='white')

									  lbl1["text"] = "Time up!"

									  tkMessageBox.showinfo("Time up!","Time up!")

									 def GetSource():

									  get_window = Tkinter.Toplevel(root)

									  get_window.title('Source File?')

									  Tkinter.Entry(get_window, width=30,

									      textvariable=source).pack()

									  Tkinter.Button(get_window, text="Change",

									      command=lambda: update_specs()).pack()

									root = Tk()

									root.title("Countdown")

									lbl1 = Label()

									lbl1.pack(fill=BOTH, expand=1)

									app = App(root)

									root.mainloop()
