In this article we will see how we can check if the checkable QCommandLinkButton checked or unchecked, by default it is not checkable although we can make it checkable any time with the help of setCheckable
method. Also when it is checkable its state is unchecked although we can programmatically make its state checked with the help of setChecked
method.
In order to do this we use isChecked
method with the command link button object
Syntax : button.isChecked()
Argument : It takes no argument
Return : It returns bool
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 , 500 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for components
def UiComponents( self ):
# creating a command link button
cl_button = QCommandLinkButton( "Press" , self )
# setting geometry
cl_button.setGeometry( 250 , 100 , 150 , 50 )
# making it checkable
cl_button.setCheckable( True )
# making its state checked
cl_button.setChecked( True )
# creating label
label = QLabel( "GeeksforGeeks" , self )
# setting label geometry
label.setGeometry( 100 , 100 , 200 , 40 )
# making label multiline
label.setWordWrap( True )
# checking if button is in checked state
value = cl_button.isChecked()
# setting text to the label
label.setText( "Checked ? " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
