In this article we will see how we can check if the QCalendarWidget is ancestor of the given widget or not. In order todo so we use isAncestorOf method, this method returns true if the calendar is a parent, (or grandparent and so on to any level), of the given child, and both widgets are within the same window; otherwise returns false.
In order to do this we will use
isAncestorOfmethod with the QCalendarWidget object.Syntax : calendar.isAncestorOf(query)
Argument : It takes QWidget object as argument
Return : It return bool
Below is the implementation
Python3
# 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) # getting third child of the calendar child = self.calendar.children()[3] # checking if the calendar is ancestor of the child value = self.calendar.isAncestorOf(child) # setting text to the label self.label.setText("Ancestor ? : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output:
