In this article we will see how we can change the border style of the combo box when it is editable and is in off state, border style can be dotted, dashed etc. When we set border to the combo box it is continuous although we can change it. Styled border will be only visible when combo box is editable and off state.

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

border : 4px black;
border-style : dotted;

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, 100, 40)
        # 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 stylesheet of the combo box
        # set the border style when it is editable
        # and in off state
                                     "border : 4px solid black"
                                     "QComboBox::editable:! on"
                                     "border : 4px black;"
                                     "border-style : dashed;"
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
