In this article we will see how we can get device pixel ratio, float value 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, for some devices it is in decimal values like 1.1, 1.2 etc .
In order to do this we will use devicePixelRatioF method with the QCalendarWidget object.
Syntax : calendar.devicePixelRatioF()
Argument : It takes no argument
Return : It return float
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 float
value = self .calendar.devicePixelRatioF()
# setting text to the label
label.setText( "Device pixel ration (Float) : " + 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 ())
