PyQt5 – Tube shaped indicator of Radio Button

In this article we will see how to make tube shaped indicator of radio button. By default radio button indicator is circular in shape. 
Below is the representation of normal radio button and a radio button whose indicator is in tube shaped. 

In order to do this we have to do the following :
1. Create a radio button. 
2. Set the border and make the radio button indicator to rectangle(height > width) in shape with the help of style sheet. 
3. Change the bottom border radius to sum of half of the width of indicator and border thickness

Style sheet code to do this –

QRadioButton::indicator
{
border : 1px solid black;
width : 12;
height : 25;
border-bottom-left-radius : 7;
border-bottom-right-radius : 7;
}

Below is the implementation – 

Python3

# 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 border to
        # indicator of thickness 1px and of black color and width and height
        # and the border radius equal to thickness of border + half of height
        self.radio_button.setStyleSheet("QRadioButton::indicator"
                                        "{"
                                        "border : 1px solid black;"
                                        "width : 12px;"
                                        "height : 25px;"
                                        "border-bottom-left-radius : 7px;"
                                        "border-bottom-right-radius : 7px;"
                                        "}")


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
