In this article we will see how we can update the QCalendarWidget. Updating means to reflect any changes that has occur at the back-end to the screen. Updating has no effect if it is disabled.

In order to do this we will use update method with the QCalendarWidget object. 

Syntax : calendar.update() 

Argument : It takes no argument 

Return : It returns None

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, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)
 
        # setting selected date
        calendar.setSelectedDate(QDate(2021, 1, 1))
 
        # updating the calendar
        calendar.update()
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
