In this article we will see how we can border to the drop arrow of the combo box when it get pressed. Drop arrow is basically a push button which when get pressed opens the list view. This customized border will only appear to the drop arrow when it get pressed. In order to do so we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::drop-arrow:pressed { border : 2px solid green; }
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 combo box widget
self .combo_box = QComboBox( self )
# setting geometry of combo box
self .combo_box.setGeometry( 200 , 150 , 150 , 30 )
# 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 code of combo box
# adding border to the drop arrow when it get pressed
self .combo_box.setStyleSheet( "QComboBox::down-arrow:pressed"
"{"
"border : 2px solid green;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
