In this article, we will see how we can check if the signals that are associated with the QCalendarWidget are in a blocked state or not. There are various signals associated with the calendar such as date change signals page change signals etc. Actions are added to the calendar using these signals only. We can block signals with the help of blockSignals method.
 

In order to do this we will use signalsBlocked method with the QCalendarWidget object.
Syntax : calendar.signalsBlocked()
Argument : It takes no argument
Return : It return bool 
 

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)
 
        # 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)
 
        # getting signals blocked state
        value = self.calendar.signalsBlocked()
 
        # setting text to the label
        label.setText("Signals Blocked : " + str(value))
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())

Output :
