PyQt5 QCalendarWidget – Setting Background Role

  • Last Updated : 02 Jul, 2021

In this article, we will see how we set the background role to the QCalendarWidget. Background role defines the brush from the calendar’s palette that is used to render the background. If no explicit background role is set, the calendar inherits its parent widget’s background role.
 

In order to do this we will use setBackgroundRole method with the QCalendarWidget object.
Syntax : calendar.setBackgroundRole(palette_object)
Argument : It takes QPalette.ColorRole object argument
Return : It return None 
 

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, 600, 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)
 
        # enabling auto fill background
        self.calendar.setAutoFillBackground(True)
 
        # setting background role
        self.calendar.setBackgroundRole(QPalette.Base)
 
        # getting palette and setting color to the background to it
        p = self.calendar.palette()
        p.setColor(self.calendar.backgroundRole(), Qt.yellow)
        self.calendar.setPalette(p)
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())

Output :
