In this article we will see how we can set different size/width borders to the down arrow, basically, when we set border to the down arrow it is of same width for all sides although we can change its color.

In order to do so we have to change the style sheet associated with the combobox, below is the stylesheet code –
Code 1

border : solid black;
border-width-top : 5px;
border-width-right : 1px;
border-width-bottom : 10px;
border-width-left : 3px;

Code 2

border : solid black;
border-width : 5px 1px 10px 3px;

Both code perform similar task just code 1 is extended version of code 2.

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)
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 80)
        # making combo box editable
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
        # adding list of items to combo box
        # setting style sheet
        # adding different border width to down arrow
                                     "border : solid black;"
                                     "border-width : 5px 1px 10px 3px;"
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
