In this article we will see how to set the background color to the non editable combo box which is currently in the OFF state and when mouse hover over it. 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 non editable and in OFF state and mouse hover over combo box. In order to do so we have to change the style sheet code, below is the style sheet code –
QComboBox::!editable:!on:hover
{
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 non editable # and when it is in OFF state and mouse hover over it self.combo_box.setStyleSheet("QComboBox::! editable:! on:hover" "{" "background-color: lightgreen;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
