Create Treeview In Python GUI Application

Intro

In this blog, I am going to create a hierarchical treeview in Python GUI application. It will display the treeview on the application screen.

Software requirement

Python 3.5 and IDLE (Python 3.5)

Programming code

#Create hiracchical treeview Application
from tkinter import *
from tkinter import ttk
app=Tk()
#App Title
app.title("Python GUI Application ")
#Lable
ttk.Label(app, text="Hierachical Treeview").pack()
#Treeview
treeview=ttk.Treeview(app)
treeview.pack()
#Treeview items
treeview.insert('','0','item1',text='Parent tree')
treeview.insert('','1','item2',text='1st Child')
treeview.insert('','end','item3',text='2nd Child')
treeview.insert('item2','end','A',text='A')
treeview.insert('item2','end','B',text='B')
treeview.insert('item2','end','C',text='C')
treeview.insert('item3','end','D',text='D')
treeview.insert('item3','end','E',text='E')
treeview.insert('item3','end','F',text='F')
treeview.move('item2','item1','end')
treeview.move('item3','item1','end')
#Calling Main()
app.mainloop()

About the code

First, I am importing the tkinter modules.

Next, assign a class and variables and give application title.

Next, create hierarchical treeview and add tree items in the code.

Finally, I have started the windows event loop by calling the mainloop method.

Then, let’s execute the code.
