PyQt5 – Background color to ComboBox if it is non editable
In this article we will see how we can set the background color to the combo box when it is in non-editable. By default combo box is of grey color although we can change its color. This background color only appear when combo box widget is in non-editable state.
There are two ways of setting background color to the combo box if it is in editable state one is to check every time if it is editable or not; if non-editable then set background color else remove the background color and the other easy way is with the help of style sheet.
In order to do this we have to change the style sheet code of the combo box, below is the style sheet code –
QComboBox::!editable { 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" ] # adding list of items to combo box self .combo_box.addItems(geek_list) # adding background color to the combo box when it is in editable state self .combo_box.setStyleSheet( "QComboBox::! editable" "{" "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 ()) |
