PyQt5 QCalendarWidget – 设置选定日期

在本文中，我们将看到如何设置 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虽然我们可以设置任何时间选择的日期。
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 setSelectedDate method with the QCalendarWidget object.
Syntax : calendar.setSelectedDate(date)
Argument : It takes QDate object as 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)
 
        # date
        date = QDate(2021, 1, 1)
 
        # setting selected date
        calendar.setSelectedDate(date)
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出：
