PyQt5 QCalendarWidget – Ensuring Paint event

In this article we will see how we can ensure the paint event of the QCalendarWidget. With the help of painter events we can paint the calendar however user wants it to be, but some times there is a need to repaint the spin box to ensure the painter event action.

In order to do this we will use repaint method with the QCalendarWidget object.
Syntax : calendar.repaint()
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
        self.calendar = QCalendarWidget(self)

        # setting geometry to the calendar
        self.calendar.setGeometry(50, 50, 400, 250)

        # setting style sheet
        self.calendar.setStyleSheet("background : lightgreen;")

        # ensuring paint event
        self.calendar.repaint()



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
