PyQt5 – Change color of pressed Radio button for checked state

In this article we will see how we can change the color of pressed radio button when it is in checked state, by default there is no color set to any state or when radio button get pressed. In order to set color to pressed radio button for checked state we have to change the style sheet for the checked state and when radio button get pressed, below is the style sheet code.

QRadioButton::checked:pressed
{
background-color : red;   
}

Below is the implementation. 

Python3

# 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
        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("Radio Button")

        # changing style sheet code of radio button
        # setting background color for checked state and when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::checked:pressed"
                                        "{"
                                        "background-color : red"
                                        "}")


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

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

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

Output :
