In this article we will see how we can set the start timer of the QCalendarWidget. In order to do this we use startTimer method, this method calls the timerEvent after the certain interval is passed. It starts a timer and returns a timer identifier, or returns zero if it could not start a timer.
In order to do this we will use startTimer method with the QCalendarWidget object.
Syntax : calendar.startTimer(milliseconds)
Argument : It takes integer as argument i.e interval time in milliseconds
Return : It return integer
Note : In order to use the startTimer we have to override the timerEvent
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
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 )
# creating label to show the properties
self .label = QLabel( self )
# setting geometry to the label
self .label.setGeometry( 100 , 280 , 250 , 60 )
# making label multi line
self .label.setWordWrap( True )
# setting text to the label
self .label.setText("Timer ID : " + str (timer_id))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
