There are basically two states in check box that are checked or unchecked, although using setTristate
method we can add an intermediate state.
checkState
method is used to check the state of the check box, it returns CheckState object but when we print it output will be as follows:
- 0 for un-checked state
- 2 for checked state
- 1 for intermediate state
Syntax : checkbox.checkState()
Argument : It takes no argument.
Return : It returns CheckState object
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( 'Geek ?' , self )
# setting geometry of check box
checkbox.setGeometry( 200 , 150 , 100 , 40 )
# getting the checked state
check = checkbox.checkState()
# printing the state
print ( "Before check status : " , check)
# checking the check box
checkbox.setChecked( True )
# getting the checked state
check = checkbox.checkState()
# printing the state
print ( "After check status : " , check)
# exiting the program
sys.exit()
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())

Output :
Before check status : 0 After check status : 2
