In this article we will see how we can change the color of radio button when it is in unchecked state and mouse hover over it, by default there is no color set to any state or when mouse hover over it of radio button.

In order to set color to radio button for unchecked state and mouse hover over it we have to change the style sheet for the unchecked state and when mouse hover on radio button, below is the style sheet code.

QRadioButton::unchecked:hover
{
background-color : red;   
}

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 color for unchecked state and mouse hover over 
        self.radio_button.setStyleSheet("QRadioButton::unchecked:hover"
                                        "{"
                                        "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())
