  • Last Updated : 22 Apr, 2020

In this article we will see how to make dotted border to the indicator of radio button. By default radio button indicator is circular and have solid black border.

In order to add dotted border to the indicator of radio button we have to change the style sheet code of indicator associated with the radio button, below is the style sheet code.

QRadioButton::indicator
{
border : 2px blue;
border-style : dotted;
}

Note : When we alter the indicator style sheet it losses its circular shape.

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 to radio button
        # setting border width and color to indicator
        # setting border style to dotted to indicator
        radio_button.setStyleSheet("QRadioButton::indicator"
                                   "{"
                                   "border : 2px green;"
                                   "border-style : dotted;"
                                   "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
