PyQt5 QCalendarWidget – 设置一周的第一天

在本文中，我们将了解如何将一周的第一天设置为 QCalendarWidget。当我们默认创建日历时，一周的第一天是星期一，尽管我们可以随时更改此设置，但日期显示在日历的第一列中。

In order to do this we will use setFirstDayOfWeek method with the QCalendarWidget object.
Syntax : calendar.setFirstDayOfWeek(Qt.Wednesday)
Argument : It takes day object as argument
Return : It return None 
 

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, 650, 400)
 
        # calling method
        self.UiComponents()
 
        # showing all the widgets
        self.show()
 
    # method for components
    def UiComponents(self):
 
        # creating a QCalendarWidget object
        self.calendar = QCalendarWidget(self)
 
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)
 
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
 
        # setting first day of week
        self.calendar.setFirstDayOfWeek(Qt.Wednesday)
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
