PyQt5 QSpinBox – 检索描述

在本文中，我们将了解如何获取旋转框的描述，描述是有关组合框的详细信息，其中讲述了功能用例和其他主要信息，以了解旋转框的工作原理。程序员使用描述来更好地理解程序。 setAccessibleDescription方法用于设置描述。

为了做到这一点，我们使用accessibleDescription 方法。

Syntax : spin_box.accessibleDescription()

Argument : It takes no argument

Return : It returns None

下面是实现

# 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, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # text for description
        text = " This is description of spin box "
  
        # adding description ot the spin box
        self.spin.setAccessibleDescription(text)
  
        # creating a label
        label = QLabel(self)
  
        # getting the description
        des = self.spin.accessibleDescription()
  
        # setting text to the label
        label.setText(des)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 30)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
