PyQt5 – Set skin to lineedit part of non-editable combobox when mouse hover

  • Last Updated : 04 May, 2020

In this article we will see how we can set skin to the line edit part of the non-editable combo box when mouse hover over it. Line edit is the part which is used to enter and view the item. Skin is basically background image which adjust itself according to the size of line edit.

Note : When we add line edit object to the combo box it will make combo box editable there is need to make it non-editable

Steps to do this :
1. Create a combo box
2. Create a QLineEdit object
3. Set skin to the QlineEdit object when mouse hover over it
4. Make the line edit non-editable
5. Add QLineEdit object to the combo box

Syntax :

# creating line edit object
line_edit = QLineEdit()

# setting skin to line edit when mouse hover over it
line_edit.setStyleSheet("QLineEdit::hover"
                        "{"
                        "border-image : url(skin.png);"
                        "}")

# making it non editable
line_edit.setReadOnly(True)

# adding line edit object to combo box
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 check-able combo box object
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 200, 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 skin to line edit when mouse hover over it
        line_edit.setStyleSheet("QLineEdit::hover"
                                "{"
                                "border-image : url(skin.png);"
                                "}")
  
        # making it non editable
        line_edit.setReadOnly(True)
  
        # adding line edit object to combo box
        self.combo_box.setLineEdit(line_edit)
  
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())
