PyQt5 QCalendarWidget – 获取最大日期

在本文中，我们将了解如何获取 QCalendarWidget 的最大日期。 QCalendarWidget 的最大日期限制用户选择在最大日期之上，即用户只能选择小于指定最大日期的日期。超过最大日期的日期将被禁用。我们使用 setMaximumDate 方法来设置最大日期。

In order to do this we will use maximumDate method with the QCalendarWidget object.
Syntax : calendar.maximumDate()
Argument : It takes no argument
Return : It return QDate object 
 

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
        calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)
 
        # upper bound date
        u_date = QDate(2020, 6, 15)
 
        # setting maximum date
        calendar.setMaximumDate(u_date)
 
        # 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 maximum date
        value = calendar.maximumDate()
 
        # setting text to the label
        label.setText("Maximum Date : " + 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：
