PyQt5 QCalendarWidget - Setting Maximum Size

PyQt5 QCalendarWidget - Setting Size Increment

Last Updated : 17 Jun, 2020

In this article we will see how we can set the size increment to 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 maybe disregarded by the window manager on X11.

In order to do this we will use setSizeIncrement method with the QCalendarWidget object. Syntax : calendar.setSizeIncrement(size) Argument : It takes QSize object as argument Return : It return None

Below is the implementation

Python3 1==

# 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))


        # 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())
