PyQt5 QCalendarWidget – Assigning Base Size value

In this article, we will see how we can set the base size value to the QCalendarWidget. By default base size has a value zero for both width and height, base size is used to calculate a proper calendar size if the calendar defines sizeIncrement i.e its size change when window size changes. Base size is the initial size of the calendar.

In order to do this we will use setBaseSize method with the QCalendarWidget object.
Syntax : calendar.setBaseSize(width, height)
Argument : It takes two integer as argument
Return : It return 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, 10, 400, 250)

        # setting base size
        self.calendar.setBaseSize(400, 25)



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

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


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

Output :
