PyQt5 QCalendarWidget 获取焦点部件

在这篇文章中，我们将看到如何获得QCalendarWidget的焦点部件。焦点部件是日历的最后一个子部件，setFocus曾被调用过。对于顶层的部件，这是一个在这个窗口被激活的情况下会得到焦点的部件。

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

语法： calendar.focusWidget()

参数： 它不需要参数

返回： 它返回子对象

下面是实现方法

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
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)

        # getting child
        child = self.calendar.children()[3]

        # setting focus reason to the child
        child.setFocus(Qt.NoFocusReason)

        # 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 widget
        value = self.calendar.focusWidget()

        # setting text to the label
        self.label.setText("Focus widget : " + 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。
