In this article we will see how we can set different size/width border to the down arrow when it gets pressed, basically, when we set border to the down arrow it is of same width for all sides although we can change its color.
In order to do so we have to change the stylesheet associated with the combobox, below is the stylesheet code –
Code 1
QComboBox::down-arrow:pressed { border : solid black; border-width-top : 5px; border-width-right : 1px; border-width-bottom : 10px; border-width-left : 3px; }
Code 2
QComboBox::down-arrow:pressed { border : solid black; border-width : 5px 1px 10px 3px; }
Both code perform similar task just code 1 is extended version of code 2.
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 to down arrow
# adding different border width it get pressed
self .combo_box.setStyleSheet( "QComboBox::down-arrow"
"{"
"border : 1px solid black;"
"}"
"QComboBox::down-arrow:pressed"
"{"
"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 :
