PyQt5 QCalendarWidget - Background Color to the months menu

Last Updated : 21 Jun, 2020

In this article we will see how we can set background color to the months menu of the QCalendarWidget. Month menu is the QMenu object child of calendar, it appear when user press on the month name so that user can select the month, setting background color to QCalendarWidget is not like setting background color to the other widgets, calendar is widget which has many child i.e component we can set background color to independent component as well. Below is how the calendar with background color on month menu will look like

In order to do this we will use setStyleSheet method with the QCalendarWidget object, below is the style sheet code

QCalendarWidget QMenu
{
background-color : lightgreen;
}

Below is the implementation

Python3 1==

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys

# QCalendarWidget Class
class 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, 500, 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 cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # setting size of the calendar
        self.calendar.resize(350, 240)

        # move the calendar
        self.calendar.move(10, 10)

        # setting stylesheet
        # adding background color to the calendar's menu
        self.calendar.setStyleSheet("QCalendarWidget QMenu"
                                    "{"
                                    "background-color : lightgreen;"
                                    "}"
                                    )



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
