PyQt5 QCalendarWidget – 访问子区域

在本文中，我们将了解如何获取 QCalendarWidget 的子区域。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。子区域是除隐藏子之外的所有子的区域（占用的区域），即所有小部件的组合区域。

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

Syntax : calendar.childrenRegion()

Argument : It takes no argument

Return : It return QRegion object

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 region 
        value = self.calendar.childrenRegion()
  
        # setting text to the label
        label.setText("Children Region : " + str(value))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
  
# start the app
sys.exit(App.exec())

输出 ：
