PyQt5 QCalendarWidget – 检查编辑焦点属性

在本文中，我们将了解如何检查 QCalendarWidget 的编辑焦点是否启用。如果启用此属性，它会使日历具有编辑焦点，在这种情况下 Qt::Key_Up 和 Qt::Key_Down 将正常传递到日历；否则，使用 Qt::Key_Up 和 Qt::Key_Down 来改变焦点。可以使用 setEditFocus 方法启用或禁用它。
注意：此功能仅在 Qt for Embedded Linux 中可用。

In order to do this we will use hasEditFocus method with the QCalendarWidget object.
Syntax : calendar.hasEditFocus()
Argument : It takes no argument
Return : It return bool

编程需要懂一点英语

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
 
 
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)
 
        # enabling edit focus
        self.calendar.setEditFocus(True)
 
        # 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)
 
        # checking edit focus
        value = self.calendar.hasEditFocus()
 
        # setting text to the label
        self.label.setText("Edit Focus : " + 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：
