PyQt5 QCalendarWidget – 让孩子使用它的类型

在本文中，我们将看到如何使用子元素的类型找到 QCalendarWidget 的子元素。日历不是一个独立的小部件，它由称为子部件的小部件组成，例如，年份的日期和旋转框以及月份的下拉菜单共同构成日历

In order to do this we will use findChild method with the QCalendarWidget object.
Syntax : calendar.findChild(type)
Argument : It takes type of the child argument
Return : It return child object

编程需要懂一点英语

注意：如果有多个具有相同类型的孩子，那么它将返回在孩子堆栈中排在第一位的那个小部件
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.calender = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calender.setGeometry(50, 10, 400, 250)
 
        # setting cursor
        self.calender.setCursor(Qt.PointingHandCursor)
 
        # creating label to show the properties
        self.label = QLabel(self)
 
        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)
 
        # making label multi line
        self.label.setWordWrap(True)
 
        # getting child through type
        value = self.calender.findChild(QItemDelegate)
 
        # setting text to the label
        self.label.setText("Child :" + 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：
