PyQt5 QCalendarWidget – 获取当前年份

在本文中，我们将了解如何获取 QCalendarWidget 的当前年份。当前年份是日历上显示的年份，即当前页面年份。我们可以借助 setCurrentPage 方法设置页面。

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

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)
 
        # year and month
        year = 1999
        month = 10
 
        # setting current page
        calendar.setCurrentPage(year, month)
 
        # 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 current year
        value = calendar.yearShown()
 
        # setting text to the label
        label.setText("Current Year : " + 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：
