PyQt5 QDoubleSpinBox – 设置后缀

在本文中，我们将了解如何设置 QDoubleSpinBox 后缀。在语言学中，后缀是放在词干之后的词缀。常见的例子是格词尾，表示名词或形容词的语法格，以及动词词尾，形成动词的变位。屈折变化后缀有时称为desinence 或语法后缀或词尾。

In order to do this we will use setSuffix method with the double spin box object.

Syntax : dd_spin.setSufix(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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating double spin box
        d_spin = QDoubleSpinBox(self)
  
        # setting geometry to the double spin box
        d_spin.setGeometry(100, 100, 150, 40)
  
        # setting suffix
        d_spin.setSuffix(" is the Value")
  
        # step type
        step_type = QAbstractSpinBox.AdaptiveDecimalStepType
  
        # adaptive step type
        d_spin.setStepType(step_type)
  
        # creating a label
        label = QLabel("GeeksforGeeks", self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 80)
  
        # making label multi line
        label.setWordWrap(True)
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
