In this article we will see how we can set the background color to the combo box when it is in off state and it get pressed. 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 off state and it get pressed. OFF state of combo box is basically when the drop down menu is not open. In order to do this we have to change the style sheet code of the combo box, below is the style sheet code –
QComboBox::!on:pressed
{
background-color : lightgreen;
}
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 OFF state # and when it get pressed self.combo_box.setStyleSheet("QComboBox::! on:pressed" "{" "background-color: lightgreen;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
