PyQt5 QCalendarWidget – 如果可能，访问每个孩子的矩形

在本文中，我们将看到如何获得 QCalendarWidget 的所有孩子的矩形。日历不仅仅是一个单一的小部件，它是许多较小的小部件的混合物，我们称之为日历的孩子。有很多子项，例如表格视图、项目委托等，我们使用 children 方法获取它的所有子项。矩形是每个孩子的边界矩形。
注意：所有孩子都没有矩形，因为它们可以是布局。

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 rectangle in the try, except block and save result in another list
5. Show the list using label

编程需要懂一点英语

下面是实现

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 rectangle
                    rect = i.childrenRect()
                except:
                    # getting rectangle
                    rect = i.rect()
                     
                # adding it to list
                value.append(rect)
 
            except:
                pass
 
        # setting text to the label
        label.setText("Rectangles : " + str(value))
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
 
# start the app
sys.exit(App.exec())
