In this article, we will see how we get the region of all the children of QCalendarWidget. Calendar is not alone a single widget it is a mixture of lots of smaller widget which we refer as calendar’s child. There are many child such as table view, item delegate, etc, we use children method to get all the children of it. Region is the region occupied by each of children. 

Note : All children don’t have rectangle as they can be a layout.

In order to do this we have to do the following : 
1. Create a calendar widget 
2. Get all the children of the calendar 
3. Traverse the list of children 
4. Try to get the visible region or children region in the try, except block and save result in another list 
5. Show the list using label 
 

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, 650, 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)
 
        # creating a label
        label = QLabel(self)
 
        # setting geometry
        label.setGeometry(50, 280, 420, 120)
 
        # making it multi line
        label.setWordWrap(True)
 
        # getting children
        children = self.calendar.children()
 
 
        value = []
        for i in children:
            try:
 
                try:
                    # getting children region
                    region = i.childrenRegion()
                except:
                    # getting visible region
                    region = i.visibleRegion()
 
                # adding it to list
                value.append(region)
 
            except:
                pass
 
        # setting text to the label
        label.setText("Regions : " + str(value))
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())


Output :
