PyQt5 QCalendarWidget – 获取它的元对象

在本文中，我们将了解如何获取 QCalendarWidget 的元对象。元对象包含有关继承 QObject 的类的信息，例如类名、超类名、属性、信号和槽。每个包含 Q_OBJECT 宏的 QObject 子类都会有一个元对象。

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

Syntax : calendar.metaObject()

Argument : It takes no argument

Return : It return QMetaObject

下面是实现

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
# QCalendarWidget Class
class 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 QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # setting geometry to the calendar
        self.calendar.setGeometry(20, 20, 300, 240)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 280, 300, 60)
  
        # creating label multi line
        label.setWordWrap(True)
  
        # getting meta object of calendar
        value = self.calendar.metaObject()
  
        # setting text to the label
        label.setText(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 ：
