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
# 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 ())
