PyQt5 – Background image to indicator of unchecked Radio button

In this article we will see how we can set background image to an indicator of radio button who is in currently unchecked state. By default there is no image associated to the unchecked state although we can add background image to it. In order to add background image to unchecked indicator of radio button we have to change the style sheet of radio button, below is the style sheet code.

QRadioButton::indicator:unchecked
{
background-image : url(image.png);
}

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 image unchecked indicator
        self.radio_button.setStyleSheet("QRadioButton::indicator:unchecked"
                                        "{"
                                        "background-image : url(image.png);"
                                        "}")


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

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

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

Output :
