PyQt5 – Different border width to lineedit part on mouse hover (for non editable Combo box)

In this article we will see how we can set different border width to the line edit part of the combo box when mouse hover over the line edit part, line edit 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.

In order to do this we have to do the following :

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. Set border with different width when mouse hover over it
6. Make line edit object non-editable(read-only)
7. Add QLineEdit object to the combo box

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)
  
        # creating line edit object
        line_edit = QLineEdit()
  
        # setting border to the line edit part
        # set different border width when mouse hover over it
        line_edit.setStyleSheet("QLineEdit"
                                "{"
                                "border : 2px solid black"
                                "}"
                                "QLineEdit::hover"
                                "{"
                                "border-width : 1px 10px 2px 5px;"
                                "}")
  
        # making line edit read only
        line_edit.setReadOnly(True)
  
        # 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())
