In this article we will see how we can set font and the size to the content of radio button, there are basically two parts of radio button one is the indicator part and the other one is the label part which contain the content. In order to change the font and the size of content we have to change the style sheet code of radio button, below is the style sheet code
QRadioButton { font : 20px Arial; }
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 )
# 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 ):
# setting font to the style sheet
self .radio_button.setStyleSheet("QRadioButton"
"{"
"font : 20px Arial;"
"}")
# adjusting the size
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 ())
