PyQt5 Combo Box – Different border color
  • Last Updated : 04 May, 2020

In this article we will see how we can create a multi-colored border to the combo box, when we set border to the combo box it is of same color for all the walls although we can change color of it respectively. Below is the representation of how multi-colored border looks like –

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

QComboBox
{
border : 5px solid;
border-color : red yellow green black;
}

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, 150, 80)
  
        # 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
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : 5px solid;"
                                     "border-color : red yellow green 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())
