Attach Vertical Scrollbar to Treeview Using Tkinter

If you want to display a list of items that contains some columns in it, then you can use the Treeview widget in Tkinter. The Treeview widget allows the user to add a large number of lists along with the properties that can be customized instantly.

If you want to attach a vertical scrollbar to the list of items in a Treeview widget, then you can define a constructor of Scrollbar and configure it by adding the command to it. Let’s take an example and see how it works.

Example

# Import the required libraries 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") # Create an instance of Style widget style= ttk.Style() style.theme_use('clam') # Add a Treeview widget and set the selection mode tree= ttk.Treeview(win, column=("c1", "c2"), show='headings', height= 8, selectmode="browse") tree.column("#1", anchor=CENTER, stretch= NO) tree.heading("#1", text="Fname") tree.column("#2", anchor=CENTER, stretch=NO) tree.heading("#2", text="Lname") # Insert the data in Treeview widget tree.insert('', 'end', text= "1",values=('Alex', 'M')) tree.insert('', 'end', text="2",values=('Belinda','Cross')) tree.insert('', 'end', text="3",values=('Ravi','Malviya')) tree.insert('', 'end', text="4",values=('Suresh','Rao')) tree.insert('', 'end', text="5",values=('Amit','Fernandiz')) tree.insert('', 'end', text= "6",values=('Raghu','Sharma')) tree.insert('', 'end',text= "7",values=('David','Nash')) tree.insert('', 'end',text= "8",values=('Ethan','Plum')) tree.insert('', 'end', text= "9", values=('Janiece','-')) # Adding a vertical scrollbar to Treeview widget treeScroll = ttk.Scrollbar(win) treeScroll.configure(command=tree.yview) tree.configure(yscrollcommand=treeScroll.set) treeScroll.pack(side= RIGHT, fill= BOTH) tree.pack() win.mainloop()

Output

Running the above code will display a window that contains a list of items in a treeview widget along with a vertical scrollbar attached to it.
