PyQt5 QCalendarWidget – Getting Height in Millimeter

In this article we will see how we can get the height of the QCalendarWidget in millimeter. In order to do this we use heightMM method which returns the height of the paint device in millimeters. Due to platform limitations, it may not be possible to use this function to determine the actual physical size of a widget on the screen.

In order to do this we will use heightMM method with the QCalendarWidget object.
Syntax : calendar.heightMM()
Argument : It takes no argument
Return : It return integer 

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 height in millimeter
        value = self.calendar.heightMM()

        # setting text to the label
        self.label.setText("Height Millimeter  : " + 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 :
