PyQt5 – Background image of checked Radio button indicator

In this article we will see how we can set background image to an indicator of radio button who is in currently checked state. By default a black circle is associated to the checked state although we can change it with background image.

In order to add background image to checked indicator of radio button we have to change the style sheet of radio button, below is the style sheet code.

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

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
        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 checked indicator
        self.radio_button.setStyleSheet("QRadioButton::indicator:checked"
                                        "{"
                                        "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 :
