PyQt5 – Change background color of Label for anti hover state

In this article we will see how we can change the background color of the label when it is in the anti hover state i.e when cursor is not hovering over it, when cursor will come upon the label it will go back to its default color and when cursor is not over the label it will change the color

In order to do this we have to change the style sheet code which is used with the label object, and have to set background color for anti hover.

Below is the stylesheet code –

QLabel::!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 label
        label = QLabel("Hello Geeks", self)

        # setting geometry of the label
        label.setGeometry(200, 150, 100, 40)

        # setting background color to label when
        # mouse is not hovering over it(anti hover)
        label.setStyleSheet("QLabel::! 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 :
