For my coursework i am doing a booking system which uses some tree views. The problem is that if ran from cmd when i double click on a row in the tree view it does not populate the boxes below it, however if i run it from the idle it does. Below is my where i have made my class and two defs which are create_GUI(for first part of gui before double click) and double click(makes second part of GUI)

when i was copyign and pasting the rest of my code that i forgot to put in the original post i found that it only stops working if i open it through the student menu(separate peice of code) but it works if i dont go through the menu
You must call mainloop() on the root window so that your program can process events.
You create LabelFrames in the parent called root, but root does not exist. To correct it pass master to the function, which receives it as root
class Application():
""" Binary to Decimal """
def __init__(self, master):
""" Initialize the frame. """

Here's my code of a gui app using tkinter library, it creats tables and prints orders for each table and gives the ability to edit orders on every table. the goal of it to know what did each table order. but editing the orders doesn't seem to work at all, I need help fixing it.
import tkinter as tk
class TableOrdersApp:
def __init__(self, master):
self.tables = []
self.table_list = tk.Listbox(master)
self.table_list.pack(side=tk.LEFT, fill=tk.BOTH)
self.table_list.bind("<<ListboxSelect>>", self.refresh_label)
self.orders_label = tk.Label(master, text="", anchor=tk.W, justify=tk.LEFT, wraplength=400)
self.orders_label.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)
self.button_frame = tk.Frame(master)
self.button_frame.pack(side=tk.RIGHT)
self.add_button = tk.Button(self.button_frame, text="Add Table", command=self.add_table)
self.add_button.pack(side=tk.TOP)
self.remove_button = tk.Button(self.button_frame, text="Remove Table", command=self.remove_table)
self.remove_button.pack(side=tk.TOP)
self.edit_button = tk.Button(self.button_frame, text="Edit Order", command=self.edit_order)
self.edit_button.pack(side=tk.TOP)
self.remove_order_button = tk.Button(self.button_frame, text="Remove Order", command=self.remove_order)
self.remove_order_button.pack(side=tk.TOP)
def add_table(self):
self.tables.append([])
self.table_list.insert(tk.END, "Table {}".format(len(self.tables)))
def remove_table(self):
index = self.table_list.curselection()[0]
self.tables.pop(index)
self.table_list.delete(index)
def refresh_label(self, event=None):
self.orders_label.config(text="\n".join(self.tables[self.table_list.curselection()[0]]))
def edit_order(self):
index = self.table_list.curselection()[0]
orders = self.tables[index]
if self.orders_label.select_present():
start_index = self.orders_label.index(tk.SEL_FIRST)
end_index = self.orders_label.index(tk.SEL_LAST)
selected_text = self.orders_label.selection_get()
num_newlines = selected_text.count("\n")
order_index = start_index.split(".")[0] - 1 - num_newlines
new_order = tk.simpledialog.askstring("Edit Order", "Enter the new order:")
orders[order_index] = new_order
self.refresh_label()
def remove_order(self):
index = self.table_list.curselection()[0]
orders = self.tables[index]
start_index = self.orders_label.index(tk.SEL_FIRST)
end_index = self.orders_label.index(tk.SEL_LAST)
num_newlines = self.orders_label.get(start_index, end_index).count("\n")
order_index = start_index.split(".")[0] - 1 - num_newlines
orders.pop(order_index)
self.refresh_label()
# Create the main window
root = tk.Tk()
# Create an instance of the TableOrdersApp class
app = TableOrdersApp(root)
# Run the main loop of the app
root.mainloop()
I tried to make it print a label and make it editable using "edit order" button, but the button itself doesn't seem to work, and I want it to print "Empty" if the table has no orders how can i do that.
Look in edit_order and remove_order function. Must easier to write less coding.
Here is code:

ive currently been trying to build a GUI application in Tkinter that takes user input from an Entry and subsiquently populate a drop down menu. The probelm is that the OptionMenu keeps throwing:

mealOneButton = Button(root, text = "query database", command = GetEntry(mealOneString))

meal = OptionMenu(root, '', *getMeal).pack()
TypeError: __init__() missing 1 required positional argument: 'value'
when i replace getMeal in:

getMeal = CsvLoadSearch(u, formatted)
meal = OptionMenu(root, '', *getMeal).pack()

I am trying to develop a class population counter. The problem is that when I run it 2 program come up. I wanted my program to be all in one. The counter keeps coming in a separate program and i can't transfer it into my actual program. How do I do this?
Here is my attached files, I am using Python
import pickle
import os.path
from tkinter import *
import tkinter.messagebox
import tkinter as tk
population = 0
def counter_label(label):
population = 0
def count():
global population
population +=1
label.config(text=str(population))
root = tk.Tk()
label = tk.Label(root)
label.pack()
counter_label(label)
button = tk.Button(root, text='Population Count', command=count).pack()
root.mainloop()
class Class:
def __init__(self, firstname, lastname):
self.firstname = firstname
self.lastname = lastname
class ClassPopulation:
def __init__(self):
window = Tk()
window.title("Class population")
self.firstnameVar = StringVar()
self.lastnameVar = StringVar()
frame1 = Frame(window)
frame1.pack()
Label(frame1, text = "First name").grid(row = 1,
column = 1, sticky = W)
Entry(frame1, textvariable = self.firstnameVar,
width = 40).grid(row = 1, column = 2)
frame2 = Frame(window)
frame2.pack()
Label(frame2, text = "Last name").grid(row = 1, column = 1, sticky = W)
Entry(frame2, textvariable = self.lastnameVar,
width = 40).grid(row = 1, column = 2)
frame3 = Frame(window)
frame3.pack()
Button(frame3, text = "Add to classlist",
command = self.processAdd).grid(row = 1, column = 1)
frame4 = Frame(window)
frame4.pack()
Label(frame4, text = "Population Count").grid(row = 1, column = 1, sticky = W)
frame5 = Frame(window)
frame5.pack()
Label(frame5, text = "0").grid(row = 1, column = 1, sticky = W)
self.classList = self.loadClass()
self.current = 0
if len(self.classList) > 0:
self.setClass()
def saveClass(self):
outfile = open("Population.dat", "wb")
pickle.dump(self.classList, outfile)
tkinter.messagebox.showinfo("Class Population","New name registered")
outfile.close()
def loadClass(self):
if not os.path.isfile("Population.dat"):
return [] # Return an empty list
try:
infile = open("Population.dat", "rb")
classList = pickle.load(infile)
except EOFError:
classList = []
infile.close()
return classList
def processAdd(self):
classList = Class(self.firstnameVar.get(), self.lastnameVar.get())
self.classList.append(classList)
self.saveClass()
def setClass(self):
self.firstnameVar.set(self.classList[self.current].firstname)
self.lastnameVar.set(self.classList[self.current].lastname)
ClassPopulation()
I think two windows are coming up is because the program runs Tk() twice - one root = tk.Tk() and another in window = Tk(). If you pass your root Tkinter instance to the class ClassPopulation, then it should show one single window.
[EDIT]
class Class:
def __init__(self, firstname, lastname):
self.firstname = firstname
self.lastname = lastname
class ClassPopulation:
def __init__(self, root_window):
window = self.root_window
window.title("Class population")
population = 0
def counter_label(label):
population = 0
def count():
global population
population +=1
label.config(text=str(population))
root = Tk()
label = tk.Label(root)
label.pack()
ClassPopulation( root )
counter_label(label)
root.mainloop()
I am trying to create a simple interface to access the name array with first, last, previous and next functionality. But the global variable I am using as a position tracker is not working. I have already referred to various question. Would really appreciate the help. Here is the code.
from tkinter import Tk, Label, Entry, Button, StringVar, IntVar
window = Tk()
name_array = [('a1','a2','a3'), ('b1','b2','b3'), ('c1','c2','c3'),('d1','d2','d3')]
global position_track
position_track = IntVar()
first_name = StringVar()
last_name = StringVar()
email = StringVar()
def return_value(pos):
first_name.set(name_array[pos][0])
last_name.set(name_array[pos][1])
email.set(name_array[pos][2])
def update_value(pos):
name_array[pos] = (first_name.get(), last_name.get(), email.get())
def first_value():
global position_track
return_value(0)
postion_track.set(0)
def last_value():
global position_track
return_value(-1)
postion_track.set(-1)
def next_value():
global position_track
if position_track.get() == len(name_array):
position_track.set(1)
temp = postion_track.get()
return_value(temp + 1)
postion_track.set(temp + 1)
def prev_value():
global position_track
if position_track.get() == -1:
position_track.set(len(name_array - 1))
temp = postion_track.get()
return_value(temp - 1)
postion_track.set(temp - 1)
label_first_name = Label(window, text = 'First Name:', justify = 'right', padx = 5)
entry_first_name = Entry(window, textvariable = first_name)
label_last_name = Label(window, text = 'Last Name:', justify = 'right', padx = 5)
entry_last_name = Entry(window, textvariable = last_name)
label_email = Label(window, text = 'Email Address:', justify = 'right', padx = 5)
entry_email = Entry(window, textvariable = email)
button_first = Button(window, text = 'First', command = first_value)
button_last = Button(window, text = 'Last', command = last_value)
button_prev = Button(window, text = 'Prev', command = prev_value)
button_next = Button(window, text = 'Next', command = next_value)
button_quit = Button(window, text = 'Quit')
button_quit.configure(command=window.destroy)
labels = [label_first_name, label_last_name, label_email]
entries = [entry_first_name, entry_last_name, entry_email]
buttons = [button_first, button_last, button_prev, button_next, button_last, button_quit]
for i in range(3):
labels[i].grid(row = i, column = 0, sticky = 'W')
entries[i].grid(row = i, column = 1, columnspan = 6)
for j in range(6):
buttons[j].grid(row = 3, column = j, sticky = 'E')
window.mainloop()
Too many typos. Plus, you don't need to declare a global in the outermost program space, just in the function defs. Corrected working code ->
from tkinter import Tk, Label, Entry, Button, StringVar, IntVar
window = Tk()
name_array = [('a1','a2','a3'), ('b1','b2','b3'), ('c1','c2','c3'),('d1','d2','d3')]
position_track = IntVar()
first_name = StringVar()
last_name = StringVar()
email = StringVar()
def return_value(pos):
first_name.set(name_array[pos][0])
last_name.set(name_array[pos][1])
email.set(name_array[pos][2])
def update_value(pos):
name_array[pos] = (first_name.get(), last_name.get(), email.get())
def first_value():
global position_track
return_value(0)
position_track.set(0)
def last_value():
global position_track
return_value(-1)
position_track.set(-1)
def next_value():
global position_track
if position_track.get() == len(name_array):
position_track.set(1)
temp = position_track.get()
return_value(temp + 1)
position_track.set(temp + 1)
def prev_value():
global position_track
if position_track.get() == -1:
position_track.set(len(name_array) - 1)
temp = position_track.get()
return_value(temp - 1)
position_track.set(temp - 1)
