PyQt5 QCalendarWidget – Clicked signal

  • Last Updated : 09 Aug, 2021

In this article we will see how we can get the clicked signal from the QCalendarWidget. Clicked signal is emitted when a mouse button is clicked i.e when the mouse was clicked on the specified date. The signal is only emitted when clicked on a valid date, e.g., dates are not outside the minimum date and maximum date. If the selection mode is NoSelection, this signal will not be emitted.

In order to do this we will use clicked method with the QCalendarWidget object.
Syntax : calendar.clicked.connect(lambda: print(“Clicked”))
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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating a QCalendarWidget object
        calender = QCalendarWidget(self)
        # setting geometry to the calender
        calender.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
        # text
        text = "Clicked Signals received (No.) : "
        # current count
        self.count = 0
        # getting the clicked signal and
        # when receives the signal printing the message
        calender.clicked.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
