PyQt5 QCalendarWidget – 获取窗口修改属性

在本文中，我们将了解如何获取 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，尽管我们可以借助setWindowModified方法来更改它。

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 isWindowModified method with the QCalendarWidget object.

Syntax : calendar.isWindowModified()

Argument : It takes no argument

Return : It returns 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, 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)
  
        # creating label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 270, 250, 60)
  
        # making label multi line
        label.setWordWrap(True)
  
        # getting window modified property
        value = calender.isWindowModified()
  
        # setting text to the label
        label.setText("Window Modified Property : " + 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：
