PyQt5 – Set skin to the down-arrow of combobox when pressed

In this article we will see how we can set skin to the down-arrow of the combo box when it get pressed. Down arrow is the push button part of the combo box which when pressed open the list view . Skin will only appear when down arrow will get pressed.

In order to do so we have to change the style sheet code associated with the combo box, below is the style sheet code

QComboBox::down-arrow::pressed
{
border-image : url(image.png);
}

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 check-able combo box object
        self.combo_box = QComboBox(self)

        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 200, 80)

        # making combo box editable
        # self.combo_box.setEditable(True)

        # 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)

        # setting style sheet to the combo box
        # adding skin to drop down arrow when it get pressed
        self.combo_box.setStyleSheet("QComboBox::down-arrow:pressed"
                                     "{"
                                     "border-image : url(image.png);"
                                     "border : 1px solid black;"
                                     "}")



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

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

window.show()

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

Output :
