PyQt5 QCalendarWidget – Blocking all Actions (Signals)

In this article we will see how we can block all the signals that are associated with the QCalendarWidget. There are various signals associated with the calendar such as date change signals page change signal etc. Actions are added to the calendar using this signals only.

In order to do this we will use blockSignals method with the QCalendarWidget object.
Syntax : calendar.blockSignals(True)
Argument : It takes bool as argument
Return: It return bool i.e previous block signal state of calendar 

Below is the implementation 

Python3

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

        # creating a label
        label = QLabel(self)

        # setting geometry
        label.setGeometry(120, 280, 200, 60)

        # making it multi line
        label.setWordWrap(True)

        # adding action to the calendar
        self.calendar.selectionChanged.connect(lambda: label.setText("Selection Changed Signal"))

        # adding action to the calendar
        self.calendar.currentPageChanged.connect(lambda: label.setText("Page Changed Signal"))

        # blocking the signals
        self.calendar.blockSignals(True)

        # setting text to the label
        label.setText("If signal will be emitted they will be shown here")



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

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


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

Output :
