Todo List App Part 1 – Python Tkinter GUI Tutorial #154

In this video we’ll start to build a cool To-Do List app with Tkinter and Python!

Our Todo list app will be able to add items, delete items, cross off items, save items to a file, and open the file for later use!

We’ll be using a Listbox for the heavy lifting of the app. We’ll change the color and font of the Listbox so it looks better than a normal list box.

This is a fun one!!

Python Code: todo.py
(Github Code)

from tkinter import *
from tkinter.font import Font

root = Tk()
root.title('Codemy.com - ToDo List!')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x500")

# Define our Font
my_font = Font(
	family="Brush Script MT",
	size=30,
	weight="bold")

# Creat frame
my_frame = Frame(root)
my_frame.pack(pady=10)

# Create listbox
my_list = Listbox(my_frame,
	font=my_font,
	width=25,
	height=5,
	bg="SystemButtonFace",
	bd=0,
	fg="#464646",
	highlightthickness=0,
	selectbackground="#a6a6a6",
	activestyle="none")

my_list.pack(side=LEFT, fill=BOTH)

# Create dummy list
stuff = ["Walk The Dog", "Buy Groceries", "Take A Nap", "Learn Tkinter", "Rule The World"]
# Add dummy list to list box
for item in stuff:
	my_list.insert(END, item)

# Create scrollbar
my_scrollbar = Scrollbar(my_frame)
my_scrollbar.pack(side=RIGHT, fill=BOTH)

# Add scrollbar
my_list.config(yscrollcommand=my_scrollbar.set)
my_scrollbar.config(command=my_list.yview)

# create entry box to add items to the list
my_entry = Entry(root, font=("Helvetica", 24))
my_entry.pack(pady=20)

# Create a button frame
button_frame = Frame(root)
button_frame.pack(pady=20)

# FUNCTIONS
def delete_item():
	my_list.delete(ANCHOR)

def add_item():
	my_list.insert(END, my_entry.get())
	my_entry.delete(0, END)

def cross_off_item():
	pass

def uncross_item():
	pass



# Add some buttons
delete_button = Button(button_frame, text="Delete Item", command=delete_item)
add_button = Button(button_frame, text="Add Item", command=add_item)
cross_off_button = Button(button_frame, text="Cross Off Item", command=cross_off_item)
uncross_button = Button(button_frame, text="Uncross Item", command=uncross_item)

delete_button.grid(row=0, column=0)
add_button.grid(row=0, column=1, padx=20)
cross_off_button.grid(row=0, column=2)
uncross_button.grid(row=0, column=3, padx=20)

root.mainloop()
