PyQt5 – Program to check radio button

In this article we will see how to set the radio button to checked state. Radio button has two states by default checked and unchecked, in checked state indicator is filled whereas in unchecked state indicator is empty.

In order to check the program we will use setChecked method.

Syntax : radio_button.setChecked(True)

Argument : It takes bool as argument.

Action performed : It will make the radio button checked.

Below is the implementation.

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):

        # creating a radio button
        radio_button = QRadioButton(self)

        # setting geometry of radio button
        radio_button.setGeometry(200, 150, 120, 40)

        # setting text to radio button
        radio_button.setText("GEEK Radio ")

        # setting radio button checked
        radio_button.setChecked(True)


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
