PyQt5 QCalendarWidget - Removing the Mask

Last Updated : 17 Jun, 2020

In this article we will see how we can remove i.e clear the mask of the QCalendarWidget. Mask are basically used to hide the calendar, with the help of mask user will not be able to see the whole calendar although the calendar will still exist but there will be mask on it.We can set mask to the calendar with the help of setMask method.

In order to do this we will use clearMask method with the QCalendarWidget object. Syntax : calendar.clearMask() Argument : It takes no argument Return : It return None

Below is the implementation

Python3 1==

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys

# QCalendarWidget Class
class Calendar(QCalendarWidget):

    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
        self.setMouseTracking(True)


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()


    # method for components
    def UiComponents(self):

        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)

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

        # setting geometry to the calendar
        self.calendar.setGeometry(20, 20, 300, 240)

        # QRect object
        rect = QRect(10, 10, 200, 100)

        # creating a QRegion
        region = QRegion(rect)

        # setting mask to the calendar
        self.calendar.setMask(region)
        
        # clearing the mask
        self.calendar.clearMask()

      

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

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

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