PyQt5 QSpinbox – 如何向其中添加行编辑对象

在本文中，我们将看到如何将行编辑对象添加到旋转框，行编辑是 PyQt5 中的小部件，用于显示文本并接受输入文本。默认情况下，旋转框有自己的行编辑对象，尽管我们可以添加自己的行编辑对象。

In order to do this we use setLineEdit method

Syntax : spin_box.setLineEdit(line_edit_object)

Argument : It takes line edit object 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")
  
        # creating a line edit object
        line = QLineEdit(self)
  
        # adding this line edit to the spin box
        self.spin.setLineEdit(line)
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
