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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 = "Clicked Signals received (No.) : " # current count self.count = 0 # getting the clicked signal and # when receives the signal printing the message calendar.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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
