PyQt5 QCalendarWidget – 检查编辑焦点属性
在这篇文章中,我们将看到我们如何检查QCalendarWidget的编辑焦点是否被启用。如果这个属性被启用,它将使日历拥有编辑焦点,在这种情况下,Qt::Key_Up和Qt::Key_Down将被正常传递给日历;否则,Qt::Key_Up和Qt::Key_Down被用来改变焦点。它可以通过setEditFocus方法来启用或禁用。
注意: 这个功能只在Qt for Embedded Linux中可用。
为了做到这一点,我们将使用QCalendarWidget对象的hasEditFocus方法。
语法: calendar.hasEditFocus()
参数: 它不需要参数
返回: 它返回bool
下面是实现
# 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 :
