PyQt5 QCalendarWidget – Mapping co-ordinate system to global
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
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 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
