PyQt5 QCalendarWidget – Mapping co-ordinate system to global
  • Last Updated : 17 Jun, 2020

In this article we will see how we can map the co-ordinate system from the QCalendarWidget to global. In order to do this we use mapToGlobal method, this translates the widget coordinate position to global screen coordinates. For example, mapToGlobal(QPoint(0, 0)) would give the global coordinates of the top-left pixel of the calendar.

In order to do this we will use mapToGlobal method with the QCalendarWidget object.

Syntax : calendar.mapToGlobal(point)

Argument : It takes QPoint object as argument

Return : It return QPoint object



Below is the implementation




# 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 calender
        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 global
        value = self.calendar.mapToGlobal(QPoint(50, 10))
  
        # setting text to the label
        self.label.setText("Mapped Point from calendar to global : " + str(value))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
