In this video I’ll show you how to create a CRM Tool using Treeview and the SQLite Database (or any database you like) with Tkinter and Python!

In this video we’ll build out the GUI of our App using the Treeview. We’ll set the colors, columns, and use some dummy data while starting out. We’ll make the rows of the Treeview widget striped.

We’ll also build a panel of text boxes that will allow us to add or update data, and we’ll build a row of buttons that will do different things in the future.

Lot’s of people have asked me how to use a Treeview with a database…this is going to be a fun one!

Python Code:
(Github Code)

from tkinter import *
from tkinter import ttk

root = Tk()
root.title(' - TreeBase')

# Add Some Style
style = ttk.Style()

# Pick A Theme

# Configure the Treeview Colors

# Change Selected Color'Treeview',
	background=[('selected', "#347083")])

# Create a Treeview Frame
tree_frame = Frame(root)

# Create a Treeview Scrollbar
tree_scroll = Scrollbar(tree_frame)
tree_scroll.pack(side=RIGHT, fill=Y)

# Create The Treeview
my_tree = ttk.Treeview(tree_frame, yscrollcommand=tree_scroll.set, selectmode="extended")

# Configure the Scrollbar

# Define Our Columns
my_tree['columns'] = ("First Name", "Last Name", "ID", "Address", "City", "State", "Zipcode")

# Format Our Columns
my_tree.column("#0", width=0, stretch=NO)
my_tree.column("First Name", anchor=W, width=140)
my_tree.column("Last Name", anchor=W, width=140)
my_tree.column("ID", anchor=CENTER, width=100)
my_tree.column("Address", anchor=CENTER, width=140)
my_tree.column("City", anchor=CENTER, width=140)
my_tree.column("State", anchor=CENTER, width=140)
my_tree.column("Zipcode", anchor=CENTER, width=140)

# Create Headings
my_tree.heading("#0", text="", anchor=W)
my_tree.heading("First Name", text="First Name", anchor=W)
my_tree.heading("Last Name", text="Last Name", anchor=W)
my_tree.heading("ID", text="ID", anchor=CENTER)
my_tree.heading("Address", text="Address", anchor=CENTER)
my_tree.heading("City", text="City", anchor=CENTER)
my_tree.heading("State", text="State", anchor=CENTER)
my_tree.heading("Zipcode", text="Zipcode", anchor=CENTER)

  • Hello John, My name is Steven Bakos. I am looking for a way to be able th change the row color within a treeview wher the data comes from a sqlite3 database. The row color I wish to change would be based on value in column one this column in my data base has either a Y or N the column represents whether the item in that row is sellable. The data base is essentially an Inventory data base. Please if there is anything I need to include in this message let me know. I am an older person and a newbie regarding python

  • Hey John
    First of all, thank you for all your videos.
    I’m trying to recreate this using my raspberrypi and visual studio, but the window never extends to fit the content, despite having coppied all the code line by line
    What am i doing wrong?

    Thank you so much

  • hello john
    can you make the crm to be able to put the data in Exel Sheet
    and make settings button because if the user want to change the text box
    i hope you do this in videos
