In this article we will see how we can check if QCalendarWidget inherits other class or not. In order to do so we use inherits property, this property returns true if the calendar object is an instance of a class that inherits className or a QObject subclass that inherits className; otherwise returns false.
Note : A class is considered to inherit itself.
In order to do this we will use inherits method with the QCalendarWidget object.
Syntax : calendar.inherits(“QObject”)
Argument : It takes string as argument i.e class name
Return : It return bool
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 , 650 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for components
def UiComponents( self ):
# creating a QCalendarWidget object
self .calendar = QCalendarWidget( self )
# setting geometry to the calendar
self .calendar.setGeometry( 50 , 10 , 400 , 250 )
# setting cursor
self .calendar.setCursor(Qt.PointingHandCursor)
# creating label to show the properties
self .label = QLabel( self )
# setting geometry to the label
self .label.setGeometry( 100 , 280 , 250 , 60 )
# making label multi line
self .label.setWordWrap( True )
# checking if calendar inherits QObject
value = self .calendar.inherits( "QObject" )
# setting text to the label
self .label.setText( "Inherits QObject : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
