PyQt5 – Add border to lineedit part of ComboBox

In this article we will see how we can set border to the line edit part of the combo box. Line edit part is the part of combo box which displays the selected item, it is editable by nature. In order to set and access the line edit object we use setLineEdit and lineEdit method respectively. Below is the representation of normal combo box vs combo box whose line edit part is having border.

In order to do this, follow these steps –

1. Create a combo box
2. Add item to the combo box
3. Create a QLineEdit object
4. Set border to the QLineEdit object
5. Add QLineEdit object to the combo box

Syntax :

# creating line edit object
line_edit = QLineEdit()

# setting border to the line edit
line_edit.setStyleSheet("QLineEdit"
                        "{"
                        "border : 2px solid green;"
                        "}")

# adding line edit object to the combo box
self.combo_box.setLineEdit(line_edit)

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 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)
  
        # creating line edit object
        line_edit = QLineEdit()
  
        # setting border to the line edit
        line_edit.setStyleSheet("QLineEdit"
                                "{"
                                "border : 2px solid green;"
                                "}")
  
        # adding line edit object to the combo box
        self.combo_box.setLineEdit(line_edit)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
