In this article we will see how we can set action to a radio button. Setting action to a radio button means adding an action to it which get called and perform some task when radio button get checked or unchecked.
In order to add action to radio button we will use toggled.connect
method.
Syntax : radio_button.toggled.connect(method_name)
Argument : It takes method name as argument.
Action performed : It will call the method associated with it when radio button will be toggled.
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 )
# adding action to radio button
self .radio_button.toggled.connect( self .action)
# method called by radio button
def action( self ):
# changing the content of label
self .label.setText( "Action performed" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
