PyQt5 QCalendarWidget – Checking if there is horizontal header or not

In this article, we will see how we check if the QCalendarWidget has the horizontal header or not. Horizontal header is the place in QCalendarWidget which shows the days name by default short form of days are shown for example Monday is displayed as Mon, below is the horizontal header representation.

Horizontal can be removed using overriding the structure of the QCalendarWidget or by setting header format value to 0, therefore in order to check if there is header or not we have to get the value of the header and have to compare with the 0 value to know if there is header or not.

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)

        # removing horizontal header
        calendar.setHorizontalHeaderFormat(0)

        # creating a label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 280, 250, 60)

        # making label multi line
        label.setWordWrap(True)

        # getting the horizontal header value
        value = calender.horizontalHeaderFormat()

        # text
        text = "There exist horizontal head"

        # comparing value with 0
        if value == 0:
            text = "There is no horizontal head"

        # setting text to the label
        label.setText(text)

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

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

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

Output :
