PyQt5 – setCheckState() method for Check Box

When we create a check box it has only two states that are checked and un-checked, although we can add an intermediate state using setTristate method. We can set check box to be checked or un-checked using setChecked but with this method we are unable to set check box to intermediate state.

setCheckState method is used to set the state of the check box it can be checked or un-checked even it can set intermediate state, it takes CheckState object as argument.

Syntax : checkbox.setCheckState(1)

Argument : It takes CheckState object as argument.

Action performed:
If we pass 0 to it, it set un-checked state to check box
If we pass 1 to it, it set intermediate state to check box
If we pass any other integer to it, it set checked state to check box

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # method for widgets
    def UiComponents(self):
        # creating the check-box
        checkbox = QCheckBox('Geek ?', self)
        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 40)
        # making check box as tristate
        # setting check box state
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
