In this article we will see how we can set different size border to the list view of the combo box when mouse hover it, list view is the item view i.e where all the items are visible. When we press the down arrow of combo box list view is opened. We can change view object any time with the help of setView
method.
There are two ways of doing this by creating our own view and changing the border of it then adding it to the combo box but it is the lengthy process as we have to add all the items to it and another way is to alter the style sheet of default view i.e list view.
Below is the stylesheet codes –
Code 1
QListView::hover { border : solid black; border-width-top : 5px; border-width-right : 1px; border-width-bottom : 10px; border-width-left : 3px; }
or
Code 2
QListView::hover { border : solid black; border-width : 5px 1px 10px 3px; }
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 )
# making combo box editable
self .combo_box.setEditable( True )
# 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
# adding different border to the list view when mouse hover
self .combo_box.setStyleSheet( "QListView"
"{"
"border : 8px solid black;"
"}"
"QListView::hover"
"{"
"border : solid black;"
"border-width : 5px 1px 10px 3px;"
"}" )
# 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 list view is opened
When mouse hover over it
