PyQt5 QCalendarWidget – Setting its Layout

In this article we will see how we can set the layout to the QCalendarWidget. In order to do this we use setLayout method, if there already is a layout manager installed on the calendar, QWidget won’t let us install another. We must first delete or update the existing layout manager (returned by layout()) before we can call setLayout() with the new layout.

In order to do this we will use setLayout method with the QCalendarWidget object.
Syntax : calendar.setLayout(layout)
Argument : It takes QLayout object as argument
Return : It return None 

Implementation Steps :
1. Create a main window 
2. Create a calendar widget and set geometry to it 
3. Get the layout of the calendar 
4. Create a label and set its properties 
5. Add this label to the layout using addWidget method 
6. Set this layout back to the calendar

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, 300)

        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # getting the current lay out
        layout = self.calendar.layout()

        # creating a label
        label = QLabel("GeeksforGeeks", self)

        # setting alignment
        label.setAlignment(Qt.AlignCenter)

        # setting style sheet to the label
        label.setStyleSheet("QLabel"
                            "{"
                            "border : 1px solid darkgrey;"
                            "background : lightgrey;"
                            "}")

        # adding label to the layout
        layout.addWidget(label)

        # setting layout back to calendar
        self.calendar.setLayout(layout)




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

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

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

Output :
