PyQt5 QCalendarWidget 获取焦点策略

在这篇文章中，我们将看到如何获得QCalendarWidget的焦点策略。这个属性决定了小部件接受键盘焦点的方式，对于日历来说，有很多焦点策略可用，比如无焦点、强焦点、轮子焦点等等。我们可以在setFocusPolicy方法的帮助下随时改变焦点策略。

为了达到这个目的，我们将使用QCalendarWidget对象的focusPolicy方法。

语法： calendar.focusPolicy()

参数： 它不需要参数

返回： 它返回焦点政策对象，但是当打印时，它显示与政策相关的值。

下面是实现方法

# importing libraries

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 focus policy to calendar
        # as no focus is set keyboard input will not work
        self.calendar.setFocusPolicy(Qt.NoFocus)

        # 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 focus policy
        value = self.calendar.focusPolicy()

        # setting text to the label
        self.label.setText("Focus Policy : " + str(value))




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

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

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