PyQt5 QCalendarWidget – 添加 QAction

在本文中，我们将了解如何将 QAction 添加到 QCalendarWidget。为了做到这一点，我们使用addAction方法，该方法将操作附加到日历的操作列表中。我们可以在actions方法的帮助下得到所有的动作。

In order to do this we will use addAction method with the QCalendarWidget object.

Syntax : calendar.addAction(action)

Argument : It takes QAction 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
  
# QCalendarWidget Class
class Calendar(QCalendarWidget):
  
    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
  
  
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
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)
  
        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)
  
        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)
  
        # creating a QAction object
        action = QAction("Geek", self)
  
        # adding action to calendar
        self.calendar.addAction(action)
  
        # 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 action of the calendar
        value = self.calendar.actions()
  
        # setting text to the label
        self.label.setText("Actions : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
