In this article we will see how to set the radio button to checked state. Radio button has two states by default checked and unchecked, in checked state indicator is filled whereas in unchecked state indicator is empty.
In order to check the program we will use setChecked
method.
Syntax : radio_button.setChecked(True)
Argument : It takes bool as argument.
Action performed : It will make the radio button checked.
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
radio_button = QRadioButton( self )
# setting geometry of radio button
radio_button.setGeometry( 200 , 150 , 120 , 40 )
# setting text to radio button
radio_button.setText( "GEEK Radio " )
# setting radio button checked
radio_button.setChecked( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
