PyQt5 – Background color to non editable ComboBox when mouse hover

In this article we will see how we can set background color to the non editable combo box when mouse hover over it. This background color will be shown only when combo box will be in non editable state and mouse hover over it.

In order to do this we have to change the style sheet code of the combo box, below is the style sheet code

QComboBox::!editable:hover
{
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):
        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 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"]


        # adding list of items to combo box
        self.combo_box.addItems(geek_list)

        # adding background color to the combo box when it is non editable
        # and mouse hover over it
        self.combo_box.setStyleSheet("QComboBox::! editable:hover"
                                     "{"
                                     "background-color: lightgreen;"
                                     "}")



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
