In this article we will see how to set the background color to the editable combo box which is currently in the off state, Off state of the combo box is when the list menu is not opened. This background color will only appear if the combo box is editable and in OFF state.
In order to do so we have to change the style sheet code, below is the style sheet code
QComboBox::editable:!on { background-color : lightgreen; }
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 )
# geek list
geek_list = [ "Sayian" , "Super Sayian" , "Super Sayian 2" , "Super Sayian B" ]
# making combo box editable
self .combo_box.setEditable( True )
# adding list of items to combo box
self .combo_box.addItems(geek_list)
# adding background color to the combo box when it is editable
# and when it is in OFF state
self .combo_box.setStyleSheet( "QComboBox::editable:! on"
"{"
"background-color: lightgreen;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
