PyQt5 QCalendarWidget – Accessing Font Metrics

In this article we will see how we can get the font metrics of the QCalendarWidget. A font is a particular size, weight and style of a typeface. Each font was a matched set of type, one piece for each glyph. By changing font we can change the style of the text present in the calendar. We can change/set font using setFont method. Font metrics calculate the size of characters and strings for a given font of calendar.

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

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)

        # font
        font = QFont('Times', 5)

        # setting font to the calendar
        self.calendar.setFont(font)

        # 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 font Metrics Object
        value = self.calendar.fontMetrics()

        # setting text to the label
        self.label.setText("Font Metrics : " + 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 :
