PyQt5 – Background color to unchecked indicator of Radio button when pressed

In this article we will see how we can set background color to the indicator of radio button which is in unchecked state and get pressed. By default a bluish color is associated to the indicator for this although we can change this color.

In order to add background color to the indicator radio button when it is in unchecked state and get pressed we have to change the style sheet code. Below is the style sheet code.

QRadiobutton::indicator:unchecked:pressed
{
background-color : lightgreen;
}

Below is the implementation.

# importing libraries

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 to unchecked indicator when it get pressed
        self.radio_button.setStyleSheet("QRadioButton::indicator:unchecked:pressed"
                                        "{"
                                        "background-color : lightgreen;"
                                        "}")


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

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

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

Output :
