PyQt5 QCalendarWidget – 获取焦点小部件

在本文中,我们将了解如何获取 QCalendarWidget 的焦点小部件。焦点小部件是已调用setFocus的日历的最后一个子项。对于顶级小部件,这是在此窗口被激活时将获得焦点的小部件

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.calender = QCalendarWidget(self)
  
        # setting geometry to the calendar
        self.calender.setGeometry(50, 10, 400, 250)
  
        # setting cursor
        self.calender.setCursor(Qt.PointingHandCursor)
  
        # getting child
        child = self.calender.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.calender.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 :
