In this article we will see how we can implement the close event for the QCalendarWidget. This event handler is called with the given event when Qt receives a window close request for a calendar from the window system. By default, the event is accepted and the calendar is closed. We can reimplement this function to change the way the widget responds to window close requests.
Below is the Calendar class code
# QCalendarWidget Class class Calendar(QCalendarWidget): # constructor def __init__(self, parent=None): super(Calendar, self).__init__(parent) # overriding the closeEvent method def closeEvent(self, event): # setting text to the label print("Close Event Called")
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the closeEvent and inside the event print the text
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
6. Close the calendar
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 # QCalendarWidget Class class Calendar(QCalendarWidget): # constructor def __init__( self , parent = None ): super (Calendar, self ).__init__(parent) # overriding the closeEvent method def closeEvent( self , event): # setting text to the label print ( "Close Event Called" ) class Window(QMainWindow): def __init__( self ): super ().__init__() # setting title self .setWindowTitle( "Python " ) # setting geometry self .setGeometry( 100 , 100 , 650 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for components def UiComponents( self ): # creating a QCalendarWidget object # as Calendar class inherits QCalendarWidget self .calendar = Calendar( self ) # setting geometry to the calendar self .calendar.setGeometry( 50 , 10 , 400 , 250 ) # setting cursor self .calendar.setCursor(Qt.PointingHandCursor) # close the calendar self .calendar.close() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
Output :
Close Event Called
