In this article we will see how we can set background image to the combo box when it is editable and mouse hover over it. By default combo box has no image although we can set image to it. Background image will appear only when combo box is in editable state and mouse hover over it. Editable state of combo box is when user and set text to the combo box, normal combo box can be made editable with the help of setEditable method.
In order to do this we have to change the style sheet associated with the combo box, below is the stylesheet code – 

background-image : url(image.png);
border :1px solid black;

Note : Combo box and text view are different things combo box consist of text view
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 check-able combo box object
        self.combo_box = QComboBox(self)
        # making combo box editable
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 200, 80)
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
        # adding list of items to combo box
        # setting style sheet of the combo box
        # adding background image to the combo box it is in editable state
        # and when mouse hover over it
                                     "background-image : url(logo.png);"
                                     "border : 2px solid black;"
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
