PyQt5 – Background color to down arrow of ComboBox when pressed

In this article we will see how we can set background color to the down arrow of combo box when it get pressed. Down arrow is the button part of the combo box which is when pressed opens the list view of items.
In order to add color to the down arrow when it get pressed we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::down-arrow:pressed
{
background-color : lightgreen;
}
Below is the implementation
| # importing libraries fromPyQt5.QtWidgets import*fromPyQt5 importQtCore, QtGui fromPyQt5.QtGui import*fromPyQt5.QtCore import*importsys   classWindow(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     defUiComponents(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 background color to the down arrow when it get pressed         self.combo_box.setStyleSheet("QComboBox::down-arrow: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())  |
