PyQt5 – Background image to viewpart of ComboBox when mouse hover

  • Last Updated : 04 May, 2020

In this article we will see how we can set background image to the view part of the combo box when mouse hover over it. View part of combo box is the drop-down menu in which all the items are shown. In order to add or retrieve view object to combo box we use setView and view method.

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

QListView::hover
{
background-image : url(image.png);
}

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)
  
        # making combo box editable
        self.combo_box.setEditable(True)
  
        # 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)
  
        # setting style sheet of the combo box
        # adding background image to the view part of combo box
        # when mouse hover over it
        print(type(self.combo_box.view()))
        self.combo_box.setStyleSheet("QListView::hover"
                                     "{"
                                     "background-image : url(logo.png);"
                                     "border : 2px solid 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())

Output :

When cursor hover over the list view
