PyQt5 QCalendarWidget 移除QAction

在这篇文章中，我们将看到如何移除QCalendarWidget的QAction。为了做到这一点，我们使用removeAction方法，这个方法会从这个日历的动作列表中移除动作。我们可以在actions方法的帮助下获得所有的动作。

为了做到这一点，我们将使用QCalendarWidget对象的removeAction方法。
语法： calendar.removeAction(action)

参数： 它需要QAction对象作为参数
返回： 它返回无

下面是实现

# 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())

输出：
