In this article we will see how we can set the background color to the editable combo box which is currently in the OFF state and when it get pressed. 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 and when combo box get pressed. Combo box is made editable with the help of setEditable method. In order to do so we have to change the style sheet code, below is the style sheet code
QComboBox::editable:!OFF:pressed { background-color : lightgreen; }
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 ) # 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) # adding background color to the combo box when it is editable # and when it is in OFF state and it get pressed self .combo_box.setStyleSheet("QComboBox::editable:! on:pressed" "{" "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 ()) |
Output :
