PyQt5 QCalendarWidget 获取焦点代理
在这篇文章中,我们将看到我们如何获得QCalendarWidget的焦点代理。焦点代理是间接地设置焦点到日历上,即通过设置焦点到它的孩子身上。例如,一些部件可以 “拥有焦点”,但是创建一个子部件,例如QLineEdit,来实际处理焦点。在这种情况下,小组件可以将行编辑设置为其焦点代理。默认情况下,日历的QTableView有焦点代理,尽管它可以在setFocusProxy方法的帮助下改变。
为了做到这一点,我们将使用QCalendarWidget对象的focusProxy方法。
语法: calendar.focusProxy()
参数: 它不需要参数
返回: 它返回QWidget对象
下面是实现的过程
# 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)
# getting child
child = self.calendar.children()[3]
# setting focus proxy
self.calendar.setFocusProxy(child)
# 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 proxy
value = self.calendar.focusProxy()
# setting text to the label
self.label.setText("Focus Proxy : " + 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:
