PyQt5 QComboBox – Setting different corners

In this article we will see how we can set different corner to the combo box, combo box widget is not like other widgets it consists of many other widget together, for example, text view, push button, line edit etc.

In order to make the combo box circular we have to change the style sheet associated with the combo box, below is the stylesheet code

QComboBox
{
border : 1px solid black;
border-top-left-radius : 20px;
border-top-right-radius : 2px;
border-bottom-left-radius:5px;
border-bottom-right-radius : 3px;
}

Note : It only makes combo box main widget i.e text view part circular it has no effect on the push button.

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, 100, 40)

        # 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 stylesheet of the combo box
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : 1px solid black;"
                                     "border-top-left-radius : 20px;"
                                     "border-top-right-radius : 2px;"
                                     "border-bottom-left-radius:5px;"
                                     "border-bottom-right-radius : 3px;"
                                     "}")

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

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

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

Output :
