PyQt5 QCommandLinkButton – Clicked Signal
In this article we will see how we can get the clicked signal of the QCommandLinkButton. This signal is emitted when the button is activated, when the shortcut key is typed, or when click or animateClick method is is called. Notably, this signal is not emitted if you call setDown, setChecked or toggle method.
In order to do this we use clicked method with the command link button object
Syntax : button.clicked.connect(method)
Argument : It takes method as argument
Action Performed : It calls the method when the clicked signal is emitted
Below is the implementation
