PyQt5 – How change size of indicator in Radio Button

In this article we will see how we can change the size of indicator in radio button, indicator is a part of radio button which is round in shape and tells about the radio button is checked or not. When we change the size of the radio button only text part size get changed, indicator size remained same.

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

QRadioButton::indicator
{
width : 20px;
height : 20px;
}

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, 40)
  
        # setting text to radio button
        self.radio_button.setText("Radio Button")
  
        # changing style sheet code of radio button
        # setting width and height of indicator 
        self.radio_button.setStyleSheet("QRadioButton::indicator"
                                        "{"
                                        "width : 20px;"
                                        "height : 20px;"
                                        "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
