PyQt5 – Setting skin to checked indicator of RadioButton

In this article we will see how we can see skin to indicator of radio button when it is in checked state. By default a black circle is associated to the checked state although we can add skin to it.Skin is basically a background image which adjust itself according to the size of indicator. This skin only appear when radio button will be in checked state.

In order to do this we have to change the style sheet of radio button, below is the style sheet code.

QRadioButton::indicator:checked
{
border-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 skin to checked indicator
        self.radio_button.setStyleSheet("QRadioButton::indicator:checked"
                                        "{"
                                        "border-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 :
