PyQt5 QCommandLinkButton – Setting Background Color for Hover states

Last Updated : 23 Feb, 2023

In this article we will see how we can set background color to the QCommandLinkButton according to the hover states. Command link button is a special type of button it has qualities of both push button and the radio button. By default, there is no extra background color to the command link button although we can set custom background color to it any time. There are basically two hover states one is hovering i.e when mouse is on the command link button and second is anti hover state i.e when the cursor is not on the command link button. In order to do this we will set style sheet code to it for that we use setStyleSheet method with the command link button object, below is the stylesheet code

QCommandLinkButton::hover
{
background-color : lightgreen;
}
QCommandLinkButton::!hover
{
background-color : yellow;
}

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, 500, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating a command link button
        cl_button = QCommandLinkButton("Press", self)

        # making it checkable
        # cl_button.setCheckable(True)

        # setting geometry
        cl_button.setGeometry(150, 100, 200, 50)

        # setting style sheet
        # setting background color according to the hover state
        cl_button.setStyleSheet("QCommandLinkButton::hover"
                                "{"
                                "border : 1px solid black;"
                                "background-color : lightgreen;"
                                "}"
                                "QCommandLinkButton::! hover"
                                "{"
                                "border : 1px solid black;"
                                "background-color : yellow;"
                                "}")




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

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

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