本文實例為大家分享了python實現倒計時小工具的具體代碼,供大家參考,具體內容如下
#!/usr/bin/env python # coding=utf-8 import threading import time import Queue from Tkinter import * import tkMessageBox import logging logging.basicConfig(level=logging.INFO) ## Communication queue commQueue = Queue.Queue() g_time = 0 ## Function run in thread def timeThread(): global g_time g_time = timeVar.get() * 60 while 1: logging.info("線程放入隊列:%d".decode("utf-8") % g_time) commQueue.put(g_time) try: root.event_generate('<>', when='tail') except TclError: break time.sleep(1) g_time -= 1 if g_time==-1: begin_btn["fg"] = "black" clockVar.set("開始計時") break def timeChanged(event): x = commQueue.get() logging.info("獲取隊列:%d".decode("utf-8") % x) minits = x//60 seconds = x%60 s = "剩余時間 {:02}:{:02}".format(minits, seconds) begin_btn["fg"] = "blue" clockVar.set(s) if x==0: tkMessageBox.showinfo("提醒","時間已到") def clock_func(*args): global g_time if threading.activeCount()>1: g_time = timeVar.get() * 60 else: th=threading.Thread(target=timeThread) th.start() ## Create main window root = Tk() root.title("計時工具") root.geometry("180x95-0-45") root.resizable(width=FALSE,height=FALSE) root.wm_attributes("-topmost",1) frame = Frame(root) frame.pack() Label(frame,text="設定時間間隔").grid(row=1,column=2) timeVar = IntVar() clockVar = StringVar() time_entry = Entry(frame, textvariable=timeVar, width=8) time_entry["justify"] = "center" time_entry.grid(row=2,column=2,sticky="W,E") begin_btn = Button(frame,textvariable=clockVar,command=clock_func) begin_btn.grid(row=3,column=2) timeVar.set(8) begin_btn["fg"] = "black" clockVar.set("開始計時") for child in frame.winfo_children(): child.grid_configure(pady=3) time_entry.focus() root.bind('< >', timeChanged) root.bind(" ",clock_func) root.mainloop()
小編再為大家分享一段代碼:Python窗口倒計時
# Countdown using Tkinter from tkinter import * import time import tkinter.messagebox 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="開始", command=self.start) self.hi_there.pack(side=LEFT) self.button = Button(frame, text="退出", 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): if k == 30: print("\a") if k== 29: print("\a") if k== 28: print("\a") lbl1["text"] = k root.update() time.sleep(1) lbl1.config(bg='red') lbl1.config(fg='white') lbl1["text"] = "時間到!" tkMessageBox.showinfo("時間到!","時間到!") 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()
