Using Radio Button Widget In Python GUI Application

Introduction

In this blog, I am going to create a Radio button widget in the Python GUI application. When a user selects the color in the radio button, the action will display the radio button color in the application screen.

Software requirement

Python 3.5 and IDLE (Python 3.5)

Programming code

#Python Radiobutton using Application
import tkinter as tk
from tkinter import ttk
win = tk.Tk()
win.title("Python GUI App")
#Label Creation
ttk.Label(win, text="Choose the color:").grid(column=0,row=0)
#Colors
Color1='Red'
Color2='Blue'
Color3='Yellow'
#Action
def radioCall():
radioSel=radioVar.get()
if radioSel== 1:
win.configure(background=Color1)
elif radioSel== 2:
win.configure(background=Color2)
elif radioSel== 3:
win.configure(background=Color3) :
#Create three Radio Button
radioVar= tk.IntVar()
radio1=tk.Radiobutton(win, text=Color1, variable=radioVar, value=1, command=radioCall)
radio1.grid(column=1,row=1, sticky=tk.W, columnspan=3)
radio2=tk.Radiobutton(win, text=Color2, variable=radioVar, value=2, command=radioCall)
radio2.grid(column=1,row=2, sticky=tk.W, columnspan=3)
radio3=tk.Radiobutton(win, text=Color3, variable=radioVar, value=3, command=radioCall)
radio3.grid(column=1,row=3, sticky=tk.W, columnspan=3)
#Calling Main()
win.mainloop()

About the code

First, I am importing the tkinter module.
Next, I will assign a class and variables and give the application title.
Next, I will create color values and radio button action condition.
Next, I will create a radio button and define values in the code.
Finally, I have started the Windows event loop by calling the mainloop method then executed the code.
