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
