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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sys# QCalendarWidget Classclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
