Question

Im posting a python program and need to convert it to C++ language.

import Tkinter
import Tkinter as tk
from Tkinter import *
import time

def current_iso8601():
    """Get current date and time in ISO8601"""
    # https://en.wikipedia.org/wiki/ISO_8601
    # https://xkcd.com/1179/
    return time.strftime("%m.%d.%Y DATE %H:%M:%S TIME")

class Application(tk.Frame):
    def __init__(self, master=None):
       
        tk.Frame.__init__(self, master)
        self.pack()
        self.createWidgets()
   
    def tstampIn(self):
       
        clockFile = open("clockTracker.txt","w")
        print "You have successfuly Clocked In \n"
        clockIn = time.strftime("%m.%d.%Y DATE %H:%M:%S TIME, CLOCK IN \n")
        print clockIn
        clockFile.write(clockIn)
        clockFile.close
       
    def tstampOut(self):

        clockFile = open("clockTracker.txt", "a")
        print "You have successfuly Clocked Out \n"
        clockOut = time.strftime("%m.%d.%Y DATE %H:%M:%S TIME, CLOCK OUT \n")
        print clockOut
        clockFile.write(clockOut)
        clockFile.close
       
    def LstampIn(self):

        clockFile = open("clockTracker.txt", "a")
        print "You have successfuly Clocked Out for LUNCH \n"
        lunchIn = time.strftime("%m.%d.%Y DATE %H:%M:%S TIME, LUNCH STARTED \n")
        print lunchIn
        clockFile.write(lunchIn)
        clockFile.close
       
    def LstampOut(self):

        clockFile = open("clockTracker.txt", "a")
        print "You have successfuly Clocked In from LUNCH \n"
        lunchOut = time.strftime("%m.%d.%Y DATE %H:%M:%S TIME, LUNCH ENDED \n")
        print lunchOut
        clockFile.write(lunchOut)
        clockFile.close
       
    def createWidgets(self):
        self.now = tk.StringVar()
        self.time = tk.Label(self, font=('Helvetica', 24))
        self.time.pack(side="top")
        self.time["textvariable"] = self.now

        self.t_stamp = Button(self, fg="green")
        self.t_stamp["text"] = "CLOCK IN"
        self.t_stamp["command"] = self.tstampIn
        self.t_stamp.pack(side="top")
       
        self.t_stamp = Button(self, fg="blue")
        self.t_stamp["text"] = "LUNCH BEGIN"
        self.t_stamp["command"] = self.LstampIn
        self.t_stamp.pack(side="left")

        self.t_stamp = Button(self, fg="green")
        self.t_stamp["text"] = "LUNCH END"
        self.t_stamp["command"] = self.LstampOut
        self.t_stamp.pack(side="right")

        self.t_stamp = Button(self, fg="blue")
        self.t_stamp["text"] = "CLOCK OUT"
        self.t_stamp["command"] = self.tstampOut
        self.t_stamp.pack(side="bottom")
       
        self.QUIT = tk.Button(self, text="QUIT", fg="red",
                                            command=root.destroy)
        self.QUIT.pack(side="bottom")

        # initial time display
        self.onUpdate()

    def onUpdate(self):
        # update displayed time
        self.now.set(current_iso8601())
        # schedule timer to call myself after 1 second
        self.after(1000, self.onUpdate)

root = tk.Tk()
app = Application(master=root)
root.mainloop()

Answer 1

This program is difficult to convert to C++ . The reasons are mentioned below.

1. TkInter is used in this Code. It is related to GUI

2. C++ don't have native GUI API library. Based on the Platform(Windows/Linux) there are some OS specific toolkits will be there like GTK etc. We have to use third party libraries like Qt or WxWidgets etc to program GUI. They are licenced. :(
