In this article we will see how we can map the co-ordinate system to the QCalendarWidget from the parent. In order to do this we use mapFromParent
method, this Translates the parent widget coordinate position to calendar coordinates.
In order to do this we will use
mapFromParent
method with the QCalendarWidget object.Syntax : calendar.mapFromParent(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 to widget co-ordinate system from parent
value = self .calendar.mapFromParent(QPoint( 50 , 10 ))
# setting text to the label
self .label.setText( "Mapped Point from 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 ())
