PyQt5 QCalendarWidget – 显示今天的日期

在本文中，我们将了解如何在 QCalendarWidget 中将今天的日期显示到屏幕上。显示今天的日期意味着显示当前日期，即日月和年，而与所选日期或日历当前位于哪个页面无关。默认情况下，日历显示今天的日期。

In order to do this we will use showToday method with the QCalendarWidget object.
Syntax : calendar.showToday()
Argument : It takes no argument
Return : It returns None

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
        calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        calendar.setGeometry(10, 10, 400, 250)
 
        # creating push button
        push = QPushButton("Today", self)
 
        # setting geometry to the push
        push.setGeometry(120, 280, 100, 40)
 
        # adding action to the push
        push.clicked.connect(lambda: do_action())
 
        def do_action():
            # showing the today's date
            calendar.showToday()
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
