PyQt5 – Find if Radio Button is checked
  • Last Updated : 22 Apr, 2020

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 of isChecked 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())
