In this article we will see how we can set the background color to the line edit part of non editable combo box, line edit part of the combo box is in which text is shown and edit.
Note : When we add line edit object to the combo box, it will make the combo box editable therefore there is a need to make line edit object non editable
In order to add background color to the line edit part of the combo box, do the following –
1. Create a combo box
2. Create a line edit widget
3. Change background color of the line edit widget
4. Make line edit object non editable
5. Add line edit widget to the combo box
Syntax :
# creating line edit widget line_edit = QLineEdit() # setting background color to the line edit widget line_edit.setStyleSheet("QLineEdit" "{" "background : lightblue;" "}") # making line edit non editable line_edit.setReadOnly(True) # adding line edit widget to combo box self.combo_box.setLineEdit(line_edit)
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)
# creating line edit widget
line_edit = QLineEdit()
# setting background color to the line edit widget
line_edit.setStyleSheet( "QLineEdit"
"{"
"background : lightblue;"
"}" )
# making line edit non editable
line_edit.setReadOnly( True )
# adding line edit widget to combo box
self .combo_box.setLineEdit(line_edit)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
