PyQt5 QCalendarWidget – Accessing Base Size value

0 0 1 minute read

In this article we will see how we can access the base size value of the QCalendarWidget. By default base size has value zero for both width and height, base size is used to calculate a proper calendar size if the calendar defines sizeIncrement i.e its size change when window size changes. Base size is the initial size of the calendar. Base size can be set tot he calendar with the help of setBaseSize method.

In order to do this we will use baseSize method with the QCalendarWidget object.
Syntax : calendar.baseSize()
Argument : It takes no argument
Return : It return QSize object

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
 
 
class Window(QMainWindow):
 
    def __init__(self):
        super().__init__()
 
        # setting title
        self.setWindowTitle("Python ")
 
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        self.calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)
 
        # setting base size
        self.calendar.setBaseSize(400, 25)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry
        label.setGeometry(120, 280, 200, 60)
 
        # making it multi line
        label.setWordWrap(True)
 
        # getting the base size
        value = self.calendar.baseSize()
 
        # setting text to the label
        label.setText("Base Size : " + str(value))
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())
