PyQt5 – isTristate() method for Check Box

When we create check box in PyQt5 application, by default it has only two states i.e True and False but with the help of setTristate method. isTristate method is used to check if the check box has two states or three states, it return True if check box has three states else it return False.

Syntax : checkbox.isTristate()

Argument : It takes no argument.

Return : It return bool, True if it is tri-state 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
        checkbox = QCheckBox('Check Box', self)

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

        # creating the third state
        checkbox.setTristate(True)

        # getting if check bos is tri-state
        check = checkbox.isTristate()

        # printing the check
        print(check)


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

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

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

Output :

True
