Hi again :)
First of all, I thought the topic name was correct. Arbitrary means as many
as one would like or a realistic number right?
I am back with one of my TKinter programs and with new questions:
I have written a program where you can book train tickets. At first , there
were only a fixed number of seats availible to book, but I have now manged
to
create as many seats as I would like. That's nice. However, this was only
for one destination. I want to be able to have as many destinations as I
want.
The numbers of seats should be the same for every destination.
I sat the entire evening and afternoon trying to get it to work yesterday,
but I have no idea on how to accomplish this. I tried using for i in range()
and while loops, without success sadly.
Here is the code so far. I translated all variable name and function names
to English, so sorry if I missed something.
from tkinter import*
import tkinter as tk
import os
NUMBEROFCHAIRS=32
class ChooseDestinationWindow(Frame):
def __init__(self,master):
super(ChooseDestinationWindow,self).__init__(master)
self.grid()
self.create_different_destinations()
def create_different_destinations(self):
self.destination1=Button(self,
text="Destination1",command=self.Destination1_function)
self.destination1.grid()
self.destination2=Button(self, text="Destination2")
self.destination2.grid()
self.destination3=Button(self,text="Destination3")
self.destination3.grid()
def Destination1_function(self):
class Seats_Destination1(tk.Button):
def __init__(self,master,index):
text=str(index+1)
self.OCCUPIED="red"
self.FREE="green"
super(Seats_Destination1, self).__init__(master,
text=text, bg=self.FREE,
command=self.PressedChair)
self.filename2 =
"Destination1{}.txt".format(index+1)
self.occupied = False
if os.path.exists(self.filename2):
self["bg"]=self.OCCUPIED
self.OCCUPIED=True
def PressedChair(self):
self.occupied = not self.occupied
if self.occupied:
self["bg"] = self.OCCUPIED
text_file=open(self.filename2,"w")
text_file.write(self.filename2)
text_file.close()
else:
self["bg"] = self.FREE
try:
os.remove(self.filename2)
except:
pass
class Destination1_Chairs(Frame):
def __init__(self,master):
super(Destination1_Chairs,self).__init__(master)
self.grid()
self.Create_Chairs()
Satt till 32.
def Create_Chairs(self):
for index in range(NUMBEROFCHAIRS):
button = Seats_Destination1(self, index)
row, column = divmod(index, 4)
button.grid(row=row, column=column)
root=Tk()
root.title("Booking Window")
app=Destination1_Chairs(root)
root.mainloop()
root=Tk()
root.title("Choose your destination")
root.geometry("900x200")
app=ChooseDestinationWindow(root)
root.mainloop()
Thanks for your time and help!
