In this article we will see how we can add border to the editable combo box when it is in off state and mouse hover over it. OFF state is basically when the combo box list view is not open. This customized border appear only when combo box will be in off state and is editable and mouse hover over it. Editable combo box can be created with the help of setEditable method. In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::editable:!off:hover { border : 3px solid blue; }
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 )
# making it editable
self .combo_box.setEditable( True )
# 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)
# editing style sheet code of combo box
# adding border to the combo box when it is editable
# and is in OFF state and mouse hover
self .combo_box.setStyleSheet("QComboBox::editable:! off:hover"
"{"
"border : 3px solid red;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
