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 ())
