PyQt5 QCalendarWidget – 获取焦点策略
在本文中,我们将了解如何获得 QCalendarWidget 的焦点策略。此属性保存小部件接受键盘焦点的方式,日历有许多可用的焦点策略,如无焦点、强焦点、滚轮焦点等。我们可以随时在setFocusPolicy
方法的帮助下更改焦点策略
In order to do this we will use focusPolicy
method with the QCalendarWidget object.
Syntax : calendar.focusPolicy()
Argument : It takes no argument
Return : It return focus policy object, but when printed it shows associated value with the policy
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.calendar = QCalendarWidget(self)
# setting geometry to the calendar
self.calendar.setGeometry(50, 10, 400, 250)
# setting cursor
self.calendar.setCursor(Qt.PointingHandCursor)
# setting focus policy to calendar
# as no focus is set keyboard input will not work
self.calendar.setFocusPolicy(Qt.NoFocus)
# 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 policy
value = self.calendar.focusPolicy()
# setting text to the label
self.label.setText("Focus Policy : " + 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 :
