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
