PyQt5 QCalendarWidget 获取给定名称对应的属性值
在这篇文章中,我们将看到如何在QCalendarWidget中获得对应给定名称的属性值,属性是由开发者添加的信息,以告诉人们日历的属性,例如,如果日历有一个被封锁的未来日期,开发者将添加这个属性,以便其他开发者可以看到这个属性并了解这个属性,它可以通过setProperty方法的帮助来添加。我们可以在dynamicPropertyNames方法的帮助下获得属性名称。
为了做到这一点,我们将使用QCalendarWidget对象的属性方法。
语法: calendar.property(name)
参数: 它需要字符串作为参数
返回: 它返回整数
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)
# setting properties
self.calendar.setProperty("Blocked", 0)
# setting properties
self.calendar.setProperty("Highlighted dates : ", 0)
# 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 the property value
value = self.calendar.property("Blocked")
# setting text to the label
self.label.setText("Blocked value :" + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.calendar.destroy()
# start the app
sys.exit(App.exec())
输出:
