In this article we will see how we can set the minimum size to the QCalendarWidget. Minimum size of the calendar is that size after which it can’t be shrunk any further, by default when we create a calendar inside the layout and when the window get extended or shrinks calendar size also increases and shrinks, therefore, there is need to set the minimum size. We can individually set minimum width and height with the help of setMinimumWidth and setMinimumHeight method respectively.

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

Syntax : calendar.setMinimumSize(size)

Argument : It takes QSize object as argument

Return : It return None

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 minimum size
        self.calendar.setMinimumSize(QSize(400, 400))
  
  
  
        # 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())

Output :

When we try to shrink the widget, calendar do not shrink after the minimum size value
