PyQt5 QCalendarWidget – 获取对象名称属性

在本文中，我们将了解如何获取 QCalendarWidget 的对象名称。对象名基本上就是给日历的对象起的名字，我们可以借助对象名在PyQt5应用中找到对象，我们可以借助findChild方法来查找。我们可以借助setObjectName方法将对象名称设置为日历。

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

Syntax : calendar.objectName()

Argument : It takes no argument

Return : It return string

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)
  
  
  
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 size of the calendar
        self.calendar.resize(300, 240)
  
        # move the calendar
        self.calendar.move(10, 10)
          
        # setting object name of calendar
        self.calendar.setObjectName("Geek")
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 280, 250, 60)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting calendar object name
        value = self.calendar.objectName()
  
        # setting text to the label
        label.setText("Object Name : " + 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 ：
