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 ):
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 )
# making check box as tristate
checkbox.setTristate( True )
# setting check box state
checkbox.setCheckState( 1 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
