Ok, this code works:
from tkinter import *
import tkinter as tk
from tkinter import filedialog
import sys, os
import io
class StatusBar(Frame):
def __init__(self, master):
Frame.__init__(self, master)
# self.file = io.open('märkning.txt', 'wt', encoding='utf8')
self.file_open = False
self.file = None
def funktion(self):
print('getting funked up')
value1 = (a1.get())
value2 = (a2.get())
value3 = (a3.get())
# value4 = (a4.get())
for parts in range(value3):
print('{}-{}-{}-{}\n'.format(value1, value2, parts + 1, parts + 1))
# self.file.writelines('{}-{}-{}-{}\n'.format(value1, value2, parts+1, parts+1))
a4.set('{}-{}-{}-{}\n'.format(value1, value2, parts + 1, parts + 1))
# Vad ska programet göra när den stängs av.
def On_exit(self):
try:
if self.file_open:
print('closing')
# stänger ner data filer och sparar data.
self.file.close()
# stäng av prgramet
self.master.destroy()
except:
self.master.destroy()
# Koden är en del av entry's endast nummer restriktion
def validate(self, action, index, value_if_allowed,
prior_value, text, validation_type, trigger_type, widget_name):
if text in '0123456789.-+':
try:
float(value_if_allowed)
return True
except ValueError:
return False
else:
return False
def file_save(self):
if not self.file_open:
print('opening')
# file = filedialog.asksaveasfilename(initialdir = "/",title = "Select file",filetypes = (("txt files","*.txt"),("all files","*.*")))
self.file = filedialog.asksaveasfile(mode='a+', filetypes=(("txt files", "*.txt"), ("all files", "*.*")))
self.file_open = True

print('writing')
self.file.write(a4.get())
# if file:

root.update()
root.resizable(width=False, height=False)
root.mainloop()The file is opened as a+ (so it picks up from the last session),
if you want new file for each session, change the mode to 'w'.
You don't need the t, as text is the default mode.
I added a file_open switch, and only open the file once, and then check is the flag is set at the and, and if so, close.
I changed the save routine a bit, removed the close, and write from a4 directly.
Hope this is what you wanted.
