In this article we will see how we can map the co-ordinate system from the QCalendarWidget. In order to do this we use mapTo method, this translates the widget coordinate position to the coordinate system of parent. The parent must not be None and must be a parent of the calling widget.
 
In order to do this we will use mapTo method with the QCalendarWidget object.
Syntax : calendar.mapTo(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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sys# QCalendarWidget Classclass 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        value = self.calendar.mapTo(self, QPoint(50, 10))        # setting text to the label        self.label.setText("Mapped Point from calendar : " + str(value))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
