Logfile for my App not "rewriting"

[Adam]

Hello,

I have a small app I am creating to crawl a directory and check that
if it is moved to another a location it's path will not break a
character limit. Usually the Windows path limit.

Now the script is working but every time I want to scan again I have
to restart for the log files to be written. I want to just be able to
change the parameter as I please and click scan without having to
restart the app for the log file to change.
(I am new to programming so the code could be untidy for want of a
better word.)

Here's the code:

#file/path finder
#indentation value 4

import Tkinter as tk


# Class to create the Application and UI
class Theapp:


    def __init__(self):

        self.labAll = tk.Label(self.mainWindow, text="All Files/
Folders:")
        self.labVi = tk.Label(self.mainWindow, text="Violating Files/
Folders:")

        #Create a sub-frame containing textbox and scrollbar for All
files scanned display
        self.allTxtf = tk.Frame(self.mainWindow, width=700,
height=164)
        self.scrlr1 = tk.Scrollbar(self.allTxtf)
        self.txtBoxall = tk.Text(self.allTxtf, wrap=tk.CHAR,
yscrollcommand=self.scrlr1.set, width=700, height=164)
        self.scrlr1.config(command = self.txtBoxall.yview)
