PyQt5 QCalendarWidget 获取焦点策略
在这篇文章中,我们将看到如何获得QCalendarWidget的焦点策略。这个属性决定了小部件接受键盘焦点的方式,对于日历来说,有很多焦点策略可用,比如无焦点、强焦点、轮子焦点等等。我们可以在setFocusPolicy方法的帮助下随时改变焦点策略。
为了达到这个目的,我们将使用QCalendarWidget对象的focusPolicy方法。
语法: calendar.focusPolicy()
参数: 它不需要参数
返回: 它返回焦点政策对象,但是当打印时,它显示与政策相关的值。
下面是实现方法
# 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:
