In this article we will see how we can set background color to the view part of the combo box when mouse hover over it. View part is basically drop down item list, which shows all the available items, we have get the view object with the help of view method, by default combo box uses QListView object.
In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code to do this
QListView::hover
{
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) # 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 view part of combo box # when mouse hover over the view part self.combo_box.setStyleSheet("QListView::hover" "{" "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 :
