PyQt5 QCalendarWidget 获取有效ID
在这篇文章中,我们将看到如何获得QCalendarWidget的有效ID,有效ID是日历的窗口系统标识符。有效标识符是指日历的本地父系窗口系统标识符(ID)。
注1: 建议你不要存储这个值,因为它有可能在运行时改变。
为了做到这一点,我们将使用QCalendarWidget对象的effectiveWinId方法。
语法: calendar.effectiveWinId()
参数: 它不需要参数
返回: 它返回本地日历ID
注意2: 这个方法应该在主窗口打开后被调用,即在主窗口类之外
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)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# getting system identifier of calendar
identifier = window.calendar.effectiveWinId()
# setting this text to the label
window.label.setText("ID : " + str(identifier))
# start the app
sys.exit(App.exec())
输出:
