In this article we will see how we can set border to the checkable QCommandLinkButton according to the checked and pressed states combined. 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 border to the command link button although when it get pressed we are able to see the border, we can set custom border to it as well. We can make the command link button checkable with the help of setCheckable method, there are basically two checked states one is checked i.e when it is in pressed state and other is the unchecked state i.e when it is in the release state. 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::checked
{
border : 4px solid green;
}
QCommandLinkButton::checked::pressed
{
border : 4px solid yellow;
}
QCommandLinkButton::!checked
{
border : 2px solid red;
}
QCommandLinkButton::checked::pressed
{
border : 2px solid pink;
}

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 border to it for checked and unchecked state
        # setting border when pressed in checked and unchecked state
        cl_button.setStyleSheet("QCommandLinkButton::! checked"
                                "{"
                                "border : 2px solid red;"
                                "}"
                                "QCommandLinkButton::checked"
                                "{"
                                "border : 4px solid green;"
                                "}"
                                "QCommandLinkButton::checked::pressed"
                                "{"
                                "border : 4px solid yellow;"
                                "}"
                                "QCommandLinkButton::! checked::pressed"
                                "{"
                                "border : 2px solid pink;"
                                "}"
                                )
 
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
