PyQt5 – Add border to non-editable ComboBox when pressed

Last Updated : 24 Jan, 2023

In this article we will see how we can add border to the combo box when it is non-editable and when it get pressed. By default combo box have border although we can change the border, combo box with customized border will only appear when it is non-editable and it is pressed. In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code

QComboBox::!non-editable:pressed
{
border : 3px solid blue;
}

Below is the implementation

Python3

# 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)
 
        # editing style sheet code of combo box
        # adding border to the combo box when it is non-editable
        # and when it get pressed
        self.combo_box.setStyleSheet("QComboBox::! editable:pressed"
                                     "{"
                                     "border : 3px solid blue;"
                                     "}")
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
