PyQt5 QSpinBox - 为行编辑部分添加背景颜色

在本文中，我们将看到如何为旋转框的行编辑部分设置背景颜色，行编辑部分是旋转框的文本部分，我们可以在其中看到文本并输入用户值。

为了做到这一点，我们必须做到以下几点——
1.创建一个旋转框
2.获取旋转框线编辑对象
3.添加订单到行编辑对象

句法 ：

# get the line edit object
line = self.spin_box.lineEdit()

# setting background color to the line edit object
line.setStyleSheet("QLineEdit"
                   "{"
                   "background-color : yellow;"
                   "}")

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")
  
        # get the line edit object
        line = self.spin.lineEdit()
  
        # setting background color to the line edit object
        line.setStyleSheet("QLineEdit"
                           "{"
                           "background-color : yellow;"
                           "}")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
