PyQt5 – isChecked() method for Check Box

isChecked method is used to know if the check box is checked or not. This method will return true if the check box is checked else it will return false. If we use this method after creating the check box it will always return False as by default check box is not checked.

Syntax : checkbox.isChecked()

Argument : It takes no argument.

Return : It return bool, true is it checked else false

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 the check-box
        self.checkbox = QCheckBox('Check box', self)

        # setting geometry of check box
        self.checkbox.setGeometry(200, 150, 100, 30)


        # connecting it to function
        self.checkbox.stateChanged.connect(self.method)

        # checking if it checked
        check = self.checkbox.isChecked()

        # printing the check
        print(check)

    def method(self):

        # printing the checked status
        print(self.checkbox.isChecked())



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :

False
True

When we run the code False will be printed and after making check box checked it will print True.
