In this article we will see how we can get the object name changed signal from the QCalendarWidget. Object name changed signal is emitted after the object’s name has been changed. The new object name is passed as objectName.
Note : This is a private signal. It can be used in signal connections but cannot be emitted by the user.
In order to do this we will use objectNameChanged method with the QCalendarWidget object.
Syntax : calendar.objectNameChanged.connect(lambda: print(“Object name change signal Signal”))
Argument : It takes method as argument
Action Performed : It will print the message whenever activated signal get emitted
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 , 50 , 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 = "Object name changed signal emitted"
# getting the object name changed signal
self .calendar.objectNameChanged.connect( lambda : label.setText(text))
# changing object name
self .calendar.setObjectName( "New Name" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
