PyQt5 QCalendarWidget – 设置窗口修改属性

在本文中，我们将了解如何设置 QCalendarWidget 的窗口修改属性。 Window modified 属性保存窗口中显示的日历是否有未保存的更改，默认情况下该属性为 False，尽管我们可以更改它。
注意：如果 QCalendarWidget 设置为已修改，则其所有祖先也将设置为已修改。

In order to do this we will use setWindowModified method with the QCalendarWidget object.
Syntax : calendar.setWindowModified(True)
Argument : It takes bool as argument
Return : It returns None 
 

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, 600, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        calender = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calender.setGeometry(10, 10, 400, 250)
 
        # setting window modified property
        calender.setWindowModified(True)
 
         
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
