PyQt5 QCalendarWidget - Getting Maximum Height

Last Updated : 17 Feb, 2023

In this article we will see how we can get the maximum height of the QCalendarWidget. Maximum height of the calendar is that height after which it can't be extended any further, by default when we create a calendar inside the layout and when the window get extended calendar size also increases therefore there is a need to set the maximum height. We can set the maximum height with the help of setMaximumHeight

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

Syntax : calendar.maximumHeight()

Argument : It takes no argument

Return : It return integer

Below is the implementation

Python3

# 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 to the layout
        layout.addWidget(self.calendar)

        # setting maximum height of the calendar
        self.calendar.setMaximumHeight(500)

        # creating a label
        label = QLabel(self)

        # adding label to the layout
        layout.addWidget(label)

        # getting maximum height
        value = self.calendar.maximumHeight()

        # setting text to the label
        label.setText("Maximum Height  : " + 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())
