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 ()) |
Output :
