PyQt5 QSpinBox – 设置后缀

在本文中，我们将看到如何为旋转框设置后缀，后缀是在值末尾添加的额外文本，不可编辑且永久。默认情况下，旋转框没有设置后缀，尽管我们可以随时设置后缀。

为此，我们将使用setSuffix方法

Syntax : spin_box.setSuffix(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, 150, 40)
  
        # setting step type
        self.spin.setSuffix(" Number(s)")
  
          
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
