PyQt5 QSpinBox – Adding background color to the line edit part

  • Last Updated : 17 May, 2020

In this article we will see how we can set background color to the line edit part of the spin box, line edit part is the text part of the spin box where we can see the text and input the user value.

In order to do this we have to do the following –
1. Create a spin box
2. Get the spin box line edit object
3. Add order to the line edit object

Syntax :

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

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

Below is the implementation




# 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())
