PyQt5 QCalendarWidget – 获取选定日期

在本文中，我们将看到如何获取 QCalendarWidget 的选定日期，选定日期是当前突出显示的日期，用户可以使用鼠标更改选定日期，默认情况下，选定日期是实时日期，尽管我们可以设置借助 setSelectedDate 方法随时选择日期。

注意：所选日期必须在 minimumDate 和 maximumDate 属性指定的日期范围内。

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

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)
 
        # date
        date = QDate(2021, 1, 1)
 
        # setting selected date
        calendar.setSelectedDate(date)
 
        # creating label
        label = QLabel(self)
 
        # setting geometry to the label
        label.setGeometry(100, 270, 250, 60)
 
        # making label multi line
        label.setWordWrap(True)
 
        # getting the selected date
        value = calendar.selectedDate()
 
        # setting text to the label
        label.setText("Selected 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：
