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()
希望本文所述对大家的Python程序设计有所帮助。
