PyQt5 – Adding action to Radio Button

In this article we will see how we can set action to a radio button. Setting action to a radio button means adding an action to it which get called and perform some task when radio button get checked or unchecked.

In order to add action to radio button we will use toggled.connect method.

Syntax : radio_button.toggled.connect(method_name)

Argument : It takes method name as argument.

Action performed : It will call the method associated with it when radio button will be toggled.

Below is the implementation.

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

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
        self.radio_button = QRadioButton(self)

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

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

        # creating label to display if it is checked or not
        self.label = QLabel("", self)

        # setting geometry of label
        self.label.setGeometry(200, 200, 150, 40)

        # adding action to radio button
        self.radio_button.toggled.connect(self.action)

    # method called by radio button
    def action(self):

        # changing the content of label
        self.label.setText("Action performed")


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

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

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

Output :
