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 ofisChecked
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 ()) |
