In this article we will see how we can change the text of pre-existing radio button when we pressed 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 –
Python3
# 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("pressed", 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 ())
