Basic Search and Autofill – Python Tkinter GUI Tutorial #162

In this video we’ll create a simple search and autofill function with Tkinter and Python.

We’ll create an entry box and a list box full of pizza toppings. As you start to type a topping into the entry box, the listbox will automatically update to show toppings that look like what you’re typing.

This is a very basic search function and the beginnings of an auto complete or autofill function that you can play with.

Python Code: fill.py
(Github Code)

from tkinter import *

root = Tk()
root.title('Codemy.com - Auto Select/Search')
root.iconbitmap('c:/gui/codemy.ico')
root.geometry("500x300")

# Update the listbox
def update(data):
	# Clear the listbox
	my_list.delete(0, END)

	# Add toppings to listbox
	for item in data:
		my_list.insert(END, item)

# Update entry box with listbox clicked
def fillout(e):
	# Delete whatever is in the entry box
	my_entry.delete(0, END)

	# Add clicked list item to entry box
	my_entry.insert(0, my_list.get(ANCHOR))

# Create function to check entry vs listbox
def check(e):
	# grab what was typed
	typed = my_entry.get()

	if typed == '':
		data = toppings
	else:
		data = []
		for item in toppings:
			if typed.lower() in item.lower():
				data.append(item)

	# update our listbox with selected items
	update(data)				


# Create a label
my_label = Label(root, text="Start Typing...",
	font=("Helvetica", 14), fg="grey")

my_label.pack(pady=20)

# Create an entry box
my_entry = Entry(root, font=("Helvetica", 20))
my_entry.pack()

# Create a listbox
my_list = Listbox(root, width=50)
my_list.pack(pady=40)

# Create a list of pizza toppings
toppings = ["Pepperoni", "Peppers", "Mushrooms",
	"Cheese", "Onions", "Ham", "Taco"]

# Add the toppings to our list
update(toppings)

# Create a binding on the listbox onclick
my_list.bind("<>", fillout)

# Create a binding on the entry box
my_entry.bind("", check)

root.mainloop()
