PyQt5 QSpinBox – 添加描述

在本文中，我们将看到如何为旋转框设置描述，描述是关于组合框的详细信息，它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。

为此，我们使用setAccessibleDescription方法。

Syntax : spin_box.setAccessibleDescription(text)

Argument : It takes string as 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)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
