In this article we will see how we can set the background color to the combo box when mouse hover over it. By default combo box is of grey color although we can change its color. This background color only appear when mouse hover over the combo box widget.
In order to do this we have to change the style sheet code of the combo box, below is the style sheet code –
QComboBox::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 ) # geek list geek_list = [ "Sayian" , "Super Sayian" , "Super Sayian 2" , "Super Sayian B" ] # making it editable self .combo_box.setEditable( True ) # adding list of items to combo box self .combo_box.addItems(geek_list) # adding background color to the combo box when mouse hover over it self .combo_box.setStyleSheet( "QComboBox::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 :
When mouse hover over combo box it looks like this
