PyQt5 QCalendarWidget – 移除 QAction

在本文中，我们将看到如何删除 QCalendarWidget 的 QAction。为此，我们使用 removeAction 方法，该方法从该日历的操作列表中删除该操作。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 removeAction method with the QCalendarWidget object.
Syntax : calendar.removeAction(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 objects
        action1 = QAction("Geek", self)
        action2 = QAction("Python", self)
 
        # creating action list
        action_list = [action1, action2]
 
        # adding actions to calendar
        self.calendar.addActions(action_list)
 
        # removing action
        self.calendar.removeAction(action1)
 
        # creating label to show the properties
        self.label = QLabel(self)
 
        # setting geometry to the label
        self.label.setGeometry(100, 280, 300, 100)
 
        # 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())
