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:
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.table_list.get(index)
print(index)
order = orders
self.orders_label.configure(text=order)
#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):
remove_orders = self.table_list.curselection()
self.table_list.delete(remove_orders)
self.orders_label.configure(text="")
#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()
Result when executes:
Result when selected:
Result when removed order:
how do i make it so when I click on a button with the items selected from the option menu, a label will display saying "you have ordered (the item selected from the option menu) and (the other item)"
food = ['Pizza','Burger','Nachos', 'French Toast']
drinks = ['Pepsi','Lemonade','Tea', 'Aperitivo Spritz']

Do you mean like this?

This a simple code in which i have created a text area using tkinter and a menu in which there is a option of find and replace in which if user click on it then a gui will appear in which user will enter a word to whom they want to replace and then a word to whom they want replace with but till now i have just created a gui . But how can i replace word with a word given by user with the text of text area that i have created.
from tkinter import *
import tkinter.font as font
from tkinter import messagebox
root = Tk()
root.title("MyCodeEditor")
editor = Text()
editor.pack()
menu_bar = Menu(root)
def find_replace():
f = Tk()
f.title("Find and Replace")
find_label = Label(f,text = "Find : ")
replace_label = Label(f,text = "Replace : ")
find_label.grid(row = 0 , column = 0)
replace_label.grid(row = 3 , column = 0)
global find_enter
global replace_enter
find_enter = Entry(f,fg = "black" , background = "blue",borderwidth = 5,width = 40)
replace_enter = Entry(f,fg = "black" , background = "blue", borderwidth = 5, width =40 )
find_enter.grid(row = 0 , column = 1)
replace_enter.grid(row = 3 , column = 1)
btn_replace = Button(f,text = 'Replace',fg = 'black',command = None)
btn_replace.grid(row=0, column = 5)
format_bar = Menu(menu_bar , tearoff = 0)
format_bar.add_command(label = 'Find and Replace',command = find_replace)
menu_bar.add_cascade(label = 'Format' ,menu = format_bar )
root.config(menu = menu_bar)
root.mainloop()
Here is a simple example (most of it is just the GUI looks, the main part is the actual replace method):
from tkinter import Tk, Text, Entry, Frame, Button, Toplevel, Label, Menu, TclError, IntVar
normal_font = ('comicsans', 10)
class FindAndReplace(Toplevel):
def __init__(self, parent, text_widget: Text):
Toplevel.__init__(self, parent)
self.focus_force()
self.title('Find and Replace')
self.geometry('500x200')
self.resizable(False, False)
self.parent = parent
self.widget = text_widget
try:
self.start_index = self.widget.index('sel.first')
self.end_index = self.widget.index('sel.last')
except TclError:
self.start_index = '1.0'
self.end_index = 'end'
self.to_find = None
self.to_replace = None
# creating find entry
find_frame = Frame(self)
find_frame.pack(expand=True, fill='both', padx=20)
Label(find_frame, text='Find:', font=normal_font).pack(side='left', fill='both', padx=20)
self.find_entry = Entry(find_frame)
self.find_entry.pack(side='right', expand=True, fill='x')
# creating replace entry
replace_frame = Frame(self)
replace_frame.pack(expand=True, fill='both', padx=20)
Label(replace_frame, text='Replace:', font=normal_font).pack(side='left', fill='both', padx=20)
self.replace_entry = Entry(replace_frame)
self.replace_entry.pack(side='right', expand=True, fill='x')
# creating buttons
button_frame = Frame(self)
button_frame.pack(expand=True, fill='both', padx=20)
Button(button_frame, text='Cancel', font=normal_font,
command=self.destroy).pack(side='right', fill='x', padx=5)
Button(button_frame, text='Replace', font=normal_font,
command=self.replace).pack(side='right', fill='x', padx=5)
def __find_get(self):
self.to_find = self.find_entry.get()
def __replace_get(self):
self.to_replace = self.replace_entry.get()
def replace(self):
self.__find_get()
self.__replace_get()
if not self.to_replace:
return
length = IntVar()
index = self.widget.search(self.to_find, self.start_index, stopindex=self.end_index, count=length)
end_index = self.widget.index(index + f'+{length.get()}c')
self.widget.delete(index, end_index)
self.widget.insert(index, self.to_replace)
root = Tk()
menu_bar = Menu(root)
file_menu = Menu(menu_bar, tearoff=0)
menu_bar.add_cascade(label='File', menu=file_menu)
file_menu.add_command(label='Find and Replace', command=lambda: FindAndReplace(root, text))
root.config(menu=menu_bar)
text = Text(root)
text.pack()
root.mainloop()
Obviously some other functionality could be added such as replace all
I've got a problem with a part of my code. It's about partial searching in treeview. I found here on stack overflow partial search method and tried to use with my code. It does't work - It doesn't give any results. Code here below:
from tkinter import *
from tkinter import ttk
root = Tk()
sv = StringVar()
ids = []
names = []
def add():
names = tree.insert("",END,values=(e0.get(),e1.get(),e2.get(),e3.get()))
for i in range(len(names)):
ids.append(tree.insert("", "end", text=names[i]))
def command(*args):
selections = []
for i in range(len(names)):
if entry.get() != "" and entry.get() == names[i][:len(entry.get())]:
selections.append(ids[i])
tree.selection_set(selections)
sv.trace("w", command)
entry = Entry(root, textvariable=sv,width=13)
entry.grid(row=2,column=1,rowspan=3,sticky=W)
e0 = Entry(root,width=15)
e0.grid(row=0,column=1,rowspan=1,sticky=W)
e1 = Entry(root,width=15)
e1.grid(row=0,column=1,rowspan=2,sticky=W)
e2 = Entry(root,width=15)
e2.grid(row=0,column=1,rowspan=3,sticky=W)
e3 = Entry(root,width=15)
e3.grid(row=0,column=1,rowspan=4,sticky=W)
btn1 = Button(root,text="add",width=5,command=add)
btn1.grid(row =0,column=0,rowspan=5)
lb1 = Label(root,text="serial num:")
lb1.grid(row =0,column=0,rowspan=1)
lb2 = Label(root,text="medicine\nname ")
lb2.grid(row =0,column=0,rowspan=2)

The variable names is not defined. You should put a similar line to the following one in the beginning of your code:
names = []
On the other hand, you have to declare the command function as follows to make it work, since the trace callback expects at least three arguments:
def command(*args):
By the way, if you do not want to loose the data in variable names, I would transform your code in a class-oriented way, such as the following one:
from tkinter import *
from tkinter import ttk
root = Tk()
sv = StringVar()
ids = []

self.e2.grid(row=0,column=1,rowspan=3,sticky=W)

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)

EDIT
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. """
self.create_GUI(master)
def create_GUI(self, root):
frame1 = tk.LabelFrame(root, text="frame1", width=300, height=130, bd=5)
