8	setGridvisible() Turns the calendar grid on or off

Example 1

The following example has a calendar widget and a label which displays the currently selected date. The complete code is as follows −

import sys
from PyQt6.QtWidgets import QApplication, QWidget, QCalendarWidget, QLabel
from PyQt6.QtCore import QDate

class Example(QWidget):
   def __init__(self):
      super().__init__()
      self.initUI()

   def initUI(self):
      cal = QCalendarWidget(self)
      cal.setGridVisible(True)
      cal.move(20, 20)
      cal.clicked[QDate].connect(self.showDate)

      self.lbl = QLabel(self)
      date = cal.selectedDate()
      self.lbl.setText(date.toString())
      self.lbl.move(20, 200)

      self.setGeometry(100, 100, 300, 300)
      self.setWindowTitle('Calendar')
      self.show()

   def showDate(self, date):
      self.lbl.setText(date.toString())

def main():
   app = QApplication(sys.argv)
   ex = Example()
   sys.exit(app.exec())

if __name__ == '__main__':
   main()

Output

The above code produces the following output −

Example 2

Following is an another demonstration of calendar using QCalendar class and its methods.

# importing libraries
from PyQt6.QtWidgets import *
from PyQt6 import QtCore, QtGui
from PyQt6.QtGui import *
from PyQt6.QtCore import *
import sys
class Window(QMainWindow):

   def __init__(self):
      super().__init__()

      # setting title
      self.setWindowTitle("Tutorialspoint")

      # setting geometry
      self.setGeometry(110, 110, 610, 410)

      # 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(50, 50, 400, 250)

# create an app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output

The above code produces the following output −
