PyQt5 QCalendarWidget – 检查是否对其祖先启用

在本文中，我们将了解如何检查 QCalendarWidget 是否对其祖先启用。为此，我们使用isEnabledTo方法。如果启用了祖先，则如果此日历将启用，则此方法返回 true；否则返回假。默认情况下，日历对其所有父级启用，尽管我们可以在setEnabled方法的帮助下更改启用属性。

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

Syntax : calendar.isEnabledTo(parent)

Argument : It takes QWidget object as argument

Return : It return bool

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)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # setting enabled property
        self.calendar.setEnabled(False)
  
        # 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)
  
        # checking if the calendar is enabled to main window
        value = self.calendar.isEnabledTo(self)
  
        # setting text to the label
        self.label.setText("Enabled to main window : " + 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：
