Select Multiple Items with Mouse in Tkinter Treeview

The purpose of Tkinter Treeview widget is to provide the user to access the data which can be calculated and modified for the future needs of the application. The Treeview widget is used to populate the given data in a table format. We can add or insert a column, insert data into rows. Sometimes, there might be a case when we want to select multiple rows at a time. This can be done by pressing the Ctrl key and selecting the row from the table.

from tkinter import *
from tkinter import ttk

# Create an instance of tkinter frame
win = Tk()

# Set the size of the tkinter window
win.geometry("700x350")
s = ttk.Style()
s.theme_use('clam')

# Add a Treeview widget
tree= ttk.Treeview(win, column=("c1", "c2","c3"), show= 'headings', height= 5)
tree.column("# 1",anchor=CENTER)
tree.heading("# 1", text= "ID")
tree.column("# 2", anchor= CENTER)
tree.heading("# 2", text= "FName")
tree.column("# 3", anchor= CENTER)
