PyQt5 – How to make Round Radio Button ?
  • Last Updated : 22 Apr, 2020

In this article we will see how to create round radio button. By default the shape of radio button is rectangular although if we set width equal to the height it become square. Below is the representation of normal bordered radio button vs the radio button round in shape.

In order to do this we have to do the following :

1. Create a radio button.
2. Set its width equal to height to make it square
3. Add border to it with the help of setStyleSheet method.
4. Set border radius to half of width.

Style sheet code to do this –

QRadioButton
{
border : 3px solid black;
border-radius : 60px;
}

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, 120)
  
        # setting text to radio button
        self.radio_button.setText("Radio Button")
  
        # changing style sheet code of radio button setting border to
        # radio button and changing radius to half of width
        self.radio_button.setStyleSheet("QRadioButton"
                                        "{"
                                        "border : 3px solid black;"
                                        "border-radius : 60px;"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
