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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
