PyQt5 QCalendarWidget – Icon Changed Signal

In this article we will see how we can get the icon changed signal from the QCalendarWidget. Icon changed signal is emitted when the calendar’s icon has changed. Setting icon also emit the same signal.

In order to do this we will use windowIconChanged method with the QCalendarWidget object. Syntax : calendar.windowIconChanged.connect(lambda: print(“Icon Changed”)) Argument : It takes no argument Action Performed : It will print the message whenever signal get emitted

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
        calendar = QCalendarWidget(self)

        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)

        # creating a label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 280, 250, 60)

        # making label multi line
        label.setWordWrap(True)

        # text
        text = "Icon Changed Signal Emitted"

        # getting the icon changed and
        # when receives the signal printing the message
        calendar.windowIconChanged.connect(lambda: label.setText(text))

        # setting icon to the calendar
        calendar.setWindowIcon(QIcon('logo.png'))


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

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

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

Output :
