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 ()) |
