PyQt5 QSpinBox - Adding border for anti hover

In this article we will see how we can add border to the spin box for anti hover, by default spin box has a black color border which did not change when mouse hover over it or not although we can change it. Anti hover means customized border will be shown when cursor is not on the spin box. In order to do this we have to change the style sheet code associated with the spin box, below is the stylesheet code

QSpinBox::!anti hover
{
border : 5px solid green;
}

Below is the implementation 

Python3

# 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 spin box
        self.spin = QSpinBox(self)

        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)

        # setting prefix to spin
        self.spin.setPrefix("Prefix ")

        # setting suffix to spin
        self.spin.setSuffix(" Suffix")

        # setting style sheet to the spin box
        # adding border to the spin box for anti hover
        self.spin.setStyleSheet("QSpinBox::! hover"
                                "{"
                                "border : 5px solid green;"
                                "}")

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
