In this article we will see how we can add border to the combo box when mouse hover. By default combo box have border although we can change the border. Below is the representation of combo box with customized border, this border will only appear when mouse hover over it.
In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::hover { border : 3px solid blue; }
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 combo box widget
self .combo_box = QComboBox( self )
# setting geometry of combo box
self .combo_box.setGeometry( 200 , 150 , 150 , 30 )
# 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)
# editing style sheet code of combo box
# adding border to the combo box when mouse hover over it
self .combo_box.setStyleSheet( "QComboBox::hover"
"{"
"border : 3px solid blue;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
