In this article, we will see how we can get the selection changed signal from the QCalendarWidget. Selection changed signal is emitted when the currently selected date is changed. The currently selected date can be changed by the user using the mouse or keyboard.
In order to do this we will use selectionChanged method with the QCalendarWidget object.
Syntax : calendar.selectionChanged.connect(lambda: print(“Selection Changed”))
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
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 = "Selection Changed signal (No.) : "
# current count
self .count = 0
# getting the selection change signal and
# when receives the signal printing the message
calendar.selectionChanged.connect( lambda : label.setText(text + str (get_count())))
# method to increase the count value
def get_count():
self .count + = 1
return self .count
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
