PyQt5 QCalendarWidget – 获取一周的第一天

在本文中,我们将了解如何获取 QCalendarWidget 一周的第一天。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。我们可以在 setFirstDayOfWeek 方法的帮助下随时更改第一天。

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)
 
        # creating label to show the properties
        self.label = QLabel(self)
 
        # setting geometry to the label
        self.label.setGeometry(100, 280, 250, 60)
 
        # making label multi line
        self.label.setWordWrap(True)
 
 
        # getting first day of the week
        value = self.calendar.firstDayOfWeek()
 
        # setting text to the label
        self.label.setText("First Day of Week :" + 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 :
