PyQt5 – Change text of pre-existing Radio button

  • Last Updated : 22 Apr, 2020

In this article we will see how we can change the text of pre-existing radio button when we press the push button, radio button text can be changed with the help of setText method.

In order to do this we have to do the following –

1. Create a radio button
2. Create a push button
3. Add action to the push button such that when button is pressed a method should be called
4. Inside the method change the text of radio button with the help of setText method

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("Radio button", self)
  
        # setting geometry of radio button
        self.radio_button.setGeometry(200, 150, 120, 40)
  
        # creating push button
        self.button = QPushButton("press", self)
  
        # adding action to push button
        self.button.pressed.connect(self.change)
  
        # setting geometry to button
        self.button.setGeometry(200, 200, 100, 40)
  
  
    # method called by push button
    def change(self):
  
        # change the text of radio button
        self.radio_button.setText("Changed")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
