In this article we will see how we can set background image to the line edit part of the combo box when mouse hover over it. Line edit is the part of combo box which is used to see the selected text and edit the text. In order to set and get the line edit object of the combo box we use setLineEdit and lineEdit method.
In order to do this we have to do the following
1. Create a combo box
2. Add items to the combo box
3. Create a QLineEdit object
4. Add background image to the QLineEdit object when mouse hover over it
5. Add line edit object to the combo box
Syntax :
# creating line edit object line_edit = QLineEdit() # setting style sheet of line edit # adding background image when mouse hover over it line_edit.setStyleSheet("QLineEdit::hover" "{" "background-image : url(logo.png);" "border : 2px solid black;" "}") # adding line edit to the 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 )
# 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)
# creating line edit object
line_edit = QLineEdit()
# setting style sheet of line edit
# adding background image when mouse hover over it
line_edit.setStyleSheet( "QLineEdit::hover"
"{"
"background-image : url(logo.png);"
"border : 2px solid black;"
"}" )
# adding line edit 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()
window.show() # start the app sys.exit(App. exec ())
