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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()window.calendar.destroy()# start the appsys.exit(App.exec()) |
Output :
