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
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sys# QCalendarWidget Classclass 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 minimum size self.calendar.setMinimumSize(QSize(400, 400)) # setting layout widget = QWidget() widget.setLayout(layout) self.setCentralWidget(widget)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output : 
When we try to shrink the widget, calendar do not shrink after the minimum size value
