PyQt5 – Set background image to Radio button indicator when mouse hover

In this article we will see how to set background image to the indicator of radio button when mouse hover over it, by default there is no image associated with it although we can add it. The background image only appear to the indicator when mouse hover over the radio button. In order to add background image to indicator of radio button we have to change the style sheet code of it. Below is the style sheet code.

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

Below is the implementation.

Python3 1==

# 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 indicator when mouse hover over it
        self.radio_button.setStyleSheet("QRadioButton::indicator:hover"
                                        "{"
                                        "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())
