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