TKinterアプリケーションでクラッシュする問題

Question

タイマー実行時に問題が発生しているプログラムを実行しています。 "start"がヒットするたびに、アプリケーションがクラッシュします。何かご意見は？

##-- Imports --## 

import time 
import openpyxl as xl 
from Tkinter import * 

##-- Classes --## 

class App(Frame): 

    def startTimer(self): 
     self.check = True 
     self.now = time.strftime("%H:%M:%S") 

     while self.check == True: 
      self.timer.configure(text = self.now) 
      time.sleep(1) 

    def initUI(self): 
     self.parent.title("Emma's Time Manager") 
     self.pack(fill = BOTH, expand = 1) 

    def initWidget(self): 

     ##Create button definitions## 
     self.buttonwidth = 12 
     self.quit = Button(self, text = "Quit", comman = self.quit, width = self.buttonwidth) 
     self.newClient = Button(self, text = "Add Client", command = lambda:self.newClientFunc(), width = self.buttonwidth) 
     self.timeStart = Button(self, text = "Start", command = lambda:self.startTimer(), width = self.buttonwidth) 
     self.timeEnd = Button(self, text = "End", command = lambda:self.endTimer(), width = self.buttonwidth) 
     self.saveBut = Button(self, text = "Save", command = lambda:self.saveFunc(), width = self.buttonwidth) 
     self.viewClient = Button(self, text = "View Client", command = lambda:self.viewCliFunc(), width = self.buttonwidth) 


     ##Create lable definitions## 
     self.timer = Label(self, text = "00:00:00") ##self.timer used as display for timer## 

     ##Create the listbox for Client Selection## 
     self.wb = xl.load_workbook("clients.xlsx") 
     self.clientNames = self.wb.get_sheet_names() 
     self.clivar = StringVar(self) 
     self.clivar.set(self.clientNames[0]) 
     self.clilist = apply(OptionMenu, (self, self.clivar) + tuple(self.clientNames)) 

     ##Create Entry Box to describe work information## 
     self.info = Entry(self, width = 50) 


     ##Create GUI for widgets## 
     self.clilist.grid(row = 0, column = 0) 
     self.timer.grid(row = 0, column = 1) 
     self.timeStart.grid(row = 0, column = 2) 
     self.timeEnd.grid(row = 0, column = 3) 
     self.info.grid(row = 1, column = 0, columnspan = 4) 
     self.newClient.grid(row = 2, column = 0) 
     self.viewClient.grid(row = 2, column = 1) 
     self.saveBut.grid(row = 2, column = 2) 
     self.quit.grid(row = 2, column = 3) 


    def __init__(self, parent): 
     Frame.__init__(self, parent, background = "light blue") 
     self.parent = parent 
     self.initUI() 
     self.initWidget() 

def main(): 
    try: 
     xl.load_workbook("clients.xlsx") 
    except: 
     temp = xl.Workbook() 
     temp.save("clients.xlsx") 
     temp.remove_sheet(temp.get_sheet_by_name("Sheet")) 

    root = Tk()  
    bob = App(root) 
    root.mainloop() 

main() 

ほとんどのプログラムはまだ完了していませんのでご注意ください。私はちょうどこのタイマーが正しく動作するように見えることができません。

あなたのループwhileの方法がないようですね。 self.checkをFalseに設定するか、ループの外にbreakを設定する必要があります。

while self.check == True: 
    self.timer.configure(text = self.now) 
    time.sleep(1)
