How To Add A Listbox In Tkinter In Python

Introduction

 

In this article, I will explain how to add a listbox in Tkinter in Python.

 

Definition

 

The Listbox keyword is used to display a list of items from which a user can select a number of items in the listbox.

 

Syntax

w = Listbox( a, option)

Parameters

 

a − This represents the parent window of the computer.

option − The list of most used options for this widget.

 

Option & Description

• bd - The bd is used to change the Border width in pixels. The default is 2.
• bg - The bg is used to change the Normal background color background.
• fg - The fg is used to change the normal foreground (text) color.
• font - The font is used to change the text font .
• Cursor - The cursor is used to set this option to a cursor name, the mouse cursor will change to that pattern when it is over the listbox.

Program

from tkinter import *
a= Tk()
a.geometry("400x400")
a.title("test")
Lb1 = Listbox(a,bg = "pink", bd = 10, fg = "black",\
              font = "Castellar", cursor = "target")
Lb1.insert(1, "lion")
Lb1.insert(2, "tiger")
Lb1.insert(3, "zebra")
Lb1.insert(4, "elephant")
Lb1.insert(5, "deer")
Lb1.insert(6, "fox")
Lb1.insert(7, "Wolf")
Lb1.insert(8, "Gorilla")
Lb1.insert(9, "Jackal")
Lb1.insert(10, "Otter")
Lb1.pack()
a.mainloop()

Output

 

• HighlightBackground - we used to focus highlight when the frame does not have a focus
• HighlightColor - we used to show the focus highlight when the frame has a focus.
• HighlightThickness - we used the thickness of the focus highlight.
• Select Background - we used background color to use displaying selected text.

Program

from tkinter import *
a= Tk()
a.geometry("400x400")
a.title("test")
listbox1=Listbox(a, background="yellow", fg="black",
                 highlightbackground="blue",highlightthickness=10,
                 selectbackground="green",highlightcolor="red")
listbox1.grid(row=1, column=1)
for x in range(1, 10):
    listbox1.insert(END, x)
a.mainloop()

Output

 

• height - The height is used to change the height on the listbox in text lines (text buttons) or pixels (images).
• width - The width is used to change the width on the listbox in letters.
• Justify - The justify is used to change the arrangement order LEFT, CENTER, RIGHT.

Program

from tkinter import *
a=Tk()
a.title("scrollbar")
list_one=Listbox(a,width=20,height=20,
                 justify=CENTER,bg="orange",bd=20)
scroll_one=Scrollbar(a,command=list_one.yview)
list_one.configure(yscrollcommand=scroll_one.set)
list_one.pack(side=LEFT)
scroll_one.pack(side=RIGHT,fill=Y)
for i in range(100):
    list_one.insert(END,i)
a.mainloop()
