Logfile for my App not "rewriting"




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):
# Create GUI parts. Will allign later with grid

(width,height, x, y)
self.labAll = tk.Label(self.mainWindow, text="All Files/
self.labVi = tk.Label(self.mainWindow, text="Violating Files/

#Create a sub-frame containing textbox and scrollbar for All
files scanned display
self.allTxtf = tk.Frame(self.mainWindow, width=700,
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)

#Create another sub-frame containing textbox and scrollbar for
the Violating files display
self.viTxtf = tk.Frame(self.mainWindow, width=700, height=164)
self.scrlr2 = tk.Scrollbar(self.viTxtf)
self. txtBoxvi = tk.Text(self.viTxtf, wrap=tk.CHAR,
yscrollcommand=self.scrlr2.set, width=700, height=164)
self.scrlr2.config(command = self.txtBoxvi.yview)

#Create another sub-frame to contain the controls
self.ctrlFrame = tk.Frame(self.mainWindow, width=700,
self.labDir = tk.Label(self.ctrlFrame, text="Dir:")
self.entDir = tk.Entry(self.ctrlFrame)
self.labTardir = tk.Label(self.ctrlFrame, text="Target Dir:")
self.entTardir = tk.Entry(self.ctrlFrame)

self.entChar = tk.Entry(self.ctrlFrame)
