PyQt5 QCalendarWidget – Mapping Co-ordinate system to Calendar co-ordinate system

In this article, we will see how we can map the co-ordinate system of the QCalendarWidget. In order to do this we use mapFrom method, this translates the calendar coordinate position from the coordinate system of parent to this widget’s coordinate system. The parent must not be None and must be a parent of the calling widget.

In order to do this we will use mapFrom method with the QCalendarWidget object.
Syntax : calendar.mapFrom(parent, point)
Argument : It takes QWidget object that is parent and the QPoint object as argument
Return : It return QPoint 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

# QCalendarWidget Class
class Calendar(QCalendarWidget):

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


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

        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)

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

        # 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)

        # mapping to widget co-ordinate system
        value = self.calendar.mapFrom(self, QPoint(50, 10))

        # setting text to the label
        self.label.setText("Mapped Point : " + 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 :
