PyQt5 QCalendarWidget 获得它的元对象

在这篇文章中，我们将看到如何获得QCalendarWidget的元对象。元对象包含了关于继承QObject的类的信息，例如：类名、超类名、属性、信号和槽。每个包含Q_OBJECT宏的QObject子类都会有一个元对象。

为了做到这一点，我们将使用QCalendarWidget对象的metaObject方法。

语法 : calendar.metaObject()

参数： 它不需要参数

返回： 它返回QMetaObject

下面是实现方法

# QCalendarWidget Class
class Calendar(QCalendarWidget):

    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)
        self.setMouseTracking(True)


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 500, 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 cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # setting geometry to the calendar
        self.calendar.setGeometry(20, 20, 300, 240)

        # creating a label
        label = QLabel(self)

        # setting geometry to the label
        label.setGeometry(100, 280, 300, 60)

        # creating label multi line
        label.setWordWrap(True)

        # getting meta object of calendar
        value = self.calendar.metaObject()

        # setting text to the label
        label.setText(str(value))


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
