In this article we will see how we can see background color to the indicator of radio button when it is in the checked state. By default a blacked circle is associated with the checked state although we can change it with background color.
In order to add background color to the indicator for the checked state we have to change the style sheet of the radio button, below is the style sheet code.
QRadioButton::indicator:checked { background-color : lightgreen; }
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 background color to indicator when it is in checked state
self .radio_button.setStyleSheet( "QRadioButton::indicator:checked"
"{"
"background-color : lightgreen;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
