PyQt5 – Change the size of Radio button according to content length

In this article, we will see how we can change the size of the radio button according to the content inside it. Basically, there is two ways to do this. First is the lengthy one in which we get the content of the radio button then we find its length then change the size of the radio button according to the length this is lengthy and will not be that accurate, second method is by using adjustSize method it will automatically change the size radio button and is more accurate.

In order to do change the radio button size according to the content we have to do the following – 
1. Create a radio button 
2. Create a push button 
3. Add action to the radio button 
4. In side the action change the size using adjustSize method 

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("Radio button", self)

        # setting geometry of radio button
        self.radio_button.setGeometry(200, 150, 120, 40)

        # adding border to the radio button
        self.radio_button.setStyleSheet("border : 2px solid green;")

        # creating push button
        self.button = QPushButton("press to change", self)

        # adding action to push button
        self.button.pressed.connect(self.change)

        # setting geometry to button
        self.button.setGeometry(100, 100, 100, 40)


    # method called by push button
    def change(self):

        # adjusting the size of radio button
        self.radio_button.adjustSize()



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

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

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

Output :
