In this article we will see if how we can find if the radio button is checked. By default the radio button is unchecked but with the help of setChecked
method we can set it to checked.
In order check if the radio button is checked or not we will do the following :
1. Create a push button
2. Create a label to tell if radio button is checked or not.
3. Connect a method to it such that if its state gets changed method should be called.
4. In method check if radio button is checked or not with the help ofisChecked
method.
5. Change the text of label according to the state.
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( "GEEK ?" )
# creating label to display if it is checked or not
self .label = QLabel("", self )
# setting geometry of label
self .label.setGeometry( 200 , 200 , 150 , 40 )
# setting callable method to radio button
self .radio_button.clicked.connect( self .check)
# method called by radio button
def check( self ):
# checking if it is checked
if self .radio_button.isChecked():
# changing text of label
self .label.setText( "It is now checked" )
# if it is not checked
else :
# changing text of label
self .label.setText("")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
