In this article we will see how we can implement the timer event for the QCalendarWidget. A timer event is sent to the calendar when the calendars startTimer interval is over. This event handler can be reimplemented in a subclass to receive calendar startTimer events which are passed in the event parameter.
Below is the Calendar class code
# QCalendarWidget Class class Calendar(QCalendarWidget): # constructor def __init__(self, parent=None): super(Calendar, self).__init__(parent) # overriding the timer event # this will show the next month def timerEvent(self, event): # show the next month window.calendar.showNextMonth()
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the timerEvent and inside the event show the next month of calendar
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
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
# QCalendarWidget Class class Calendar(QCalendarWidget):
# constructor
def __init__( self , parent = None ):
super (Calendar, self ).__init__(parent)
# overriding the timer event
# this will show the next month
def timerEvent( self , event):
# show the next month
window.calendar.showNextMonth()
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)
# starting the calendar timer
# passing 1000 milliseconds as parameter
timer_id = self .calendar.startTimer( 1000 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
