PyQt5 – How to change indicator border in Radio Button

In this article we will see how to change the border of the radio button. By default indicator is round and has a black border although we can change the size and the color of the border.

In order to change the border of the indicator we have to change the style sheet of the indicator associated with the radio button. Below is the style sheet code.

QRadioButton::indicator
{
border : 2px solid green;
}

Note : When we alter style sheet of indicator it shapes changes to square from circle.

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
        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 border to the indicator
        radio_button.setStyleSheet("QRadioButton::indicator"
                                   "{"
                                   "border : 2px solid green"
                                   "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
