PyQt5 – Background color of pressed radio button

In this article we will see how we can set color to the pressed radio button, by default there is no color set to the radio button when it get pressed. Pressed button color appear every time when radio button is checked or unchecked.

In order to set background color to the pressed radio button we have to change the style sheet code, below is the style sheet code.

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

Below is the implementation

# importing libraries

from PyQt5 import QtCore, QtGui
from PyQt5.QtGui 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 pressed radio button
        self.radio_button.setStyleSheet("QRadioButton::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 :
