PyQt5 QCalendarWidget – Mapping co-ordinate system to Parent

In this article we will see how we can map the co-ordinate system from the QCalendarWidget to parent. In order to do this we use mapToParent method, this translates the widget coordinate position to a coordinate in the parent widget.

In order to do this we will use mapToParent method with the QCalendarWidget object.
Syntax : calendar.mapToParent(point)
Argument : It takes 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 from calendar co-ordinate system to parent
        value = self.calendar.mapToParent(QPoint(50, 10))

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