In this article we will see how we can get device pixel ratio of the QCalendarWidget. The device pixel ratio is the ratio between physical pixels and logical pixels of the calendar. Common values are 1 for normal-dpi displays and 2 for high-dpi “retina” displays.

In order to do this we will use devicePixelRatio method with the QCalendarWidget object. Syntax : calendar.devicePixelRatio() Argument : It takes no argument Return : It return integer

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
 
 
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
        self.calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)
 
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry
        label.setGeometry(50, 280, 420, 120)
 
        # making it multi line
        label.setWordWrap(True)
 
        # getting device pixel ratio
        value = self.calendar.devicePixelRatio()
         
        # setting text to the label
        label.setText("Device pixel ration :  " + str(value))
        
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
window.calendar.destroy()
 
 
# start the app
sys.exit(App.exec())
