PyQt5 QCalendarWidget – Showing Previous Month

In this article we will see how we can show the previous month of the QCalendarWidget to the screen. Showing the previous month means the previous year relative to the currently displayed month. 
Note : The selected date is not changed.

In order to do this we will use showPreviousMonth method with the QCalendarWidget object.
Syntax : calendar.showPreviousMonth()
Argument : It takes no argument
Return : It returns 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
        calendar = QCalendarWidget(self)

        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)

        # creating push button
        push = QPushButton("Previous Month", self)

        # setting geometry to the push
        push.setGeometry(120, 280, 100, 40)

        # adding action to the push
        push.clicked.connect(lambda: do_action())

        def do_action():
            # showing previous month
            calendar.showPreviousMonth()




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

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

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

Output :
