In this article we will see how to set the background color to the editable combo box which is currently in the on state. On state of the combo box is when the list menu is opened. This background color will only appear if the combo box is editable and in ON state.

In order to do so we have to change the style sheet code, below is the style sheet code –

background-color : lightgreen;

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        # showing all the widgets
    # method for widgets
    def UiComponents(self):
        # creating a combo box widget
        self.combo_box = QComboBox(self)
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 30)
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
        # making combo box editable
        # adding list of items to combo box
        # adding background color to the combo box when it is editable
        # and when it is in ON state
                                     "background-color: lightgreen;"
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
