In this article we will see how we can get the size increment of the QCalendarWidget. Size increment is used when calendar size is changeable with the change main window size.By default, for a newly-created calendar, this property contains a size with zero width and height.

Note : The size increment has no effect under Windows, and may be disregarded by the window manager on X11.

In order to do this we will use sizeIncrement method with the QCalendarWidget object.

Syntax : calendar.sizeIncrement()

Argument : It takes no argument

Return : It return QSize object

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)
        self.setMouseTracking(True)
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
  
    # method for components
    def UiComponents(self):
  
        # creating a layout
        layout = QVBoxLayout()
  
        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # adding calendar tot he layout
        layout.addWidget(self.calendar)
  
        # setting size increment
        self.calendar.setSizeIncrement(QSize(20, 20))
  
        # creating a label
        label = QLabel(self)
  
        # adding label to the layout
        layout.addWidget(label)
  
        # getting size increment
        value = self.calendar.sizeIncrement()
  
        # setting text to the label
        label.setText("Size Increment : " + str(value))
  
        # setting layout
        widget = QWidget()
        widget.setLayout(layout)
        self.setCentralWidget(widget)
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
