In this article we will see how we can set background image to the combo box when it is off state and mouse hover over the combo box. By default combo box has no image although we can set image to it. Background image will appear only when combo box is in off state and cursor is over the combo box. OFF state is when the list view is not open. In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::!off:hover { background-image : url(image.png); border :1px solid black; }
Below is the implementation
Python3
# 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)
# setting style sheet of the combo box
# adding background image to the combo box it is in OFF state
# and mouse hover over the combo box
self .combo_box.setStyleSheet("QComboBox::! on: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 ())
