PyQt5 – Setting color to indicator of Radio Button

In this article we will see how to set color to the indicator of the radio button. By default white color is associated with the indicator although we can change the color with the help of style sheet of indicator associated with it.

In order to change the color of indicator we have set the background color to a indicator in the style sheet. Below is the style sheet code to do this.

QRadioButton
{
background-color : lightgreen;
}

Note : When we alter the style sheet code associated with the indicator the shape of the indicator get set to square.

Below is the implementation.

# importing libraries

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
        radio_button = QRadioButton(self)

        # setting geometry of radio button
        radio_button.setGeometry(200, 150, 120, 40)

        # setting text to radio button
        radio_button.setText("Radio Button")

        # setting style sheet associated with the radio button
        # adding color to the indicator
        radio_button.setStyleSheet("QRadioButton::indicator"
                                   "{"
                                   "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 :
