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
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 = "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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
