clipboard-changed

Arguments: clipboard-format

This generic function is called whenever the contents of the Lisp clipboard stack changes. An application could add a method to this generic function to catch whenever this happens.

The Lisp clipboard and the Windows clipboard usually change at the same time when functions such as push-lisp-clipboard, pop-lisp-clipboard, copy-command, and cut-command are called, but if the function (setf clipboard-object) is called directly to change the Windows clipboard, then the Lisp clipboard is not changed and clipboard-changed is not called.

The argument is the current value of *clipboard*, reflecting the new state. This value is a list of conses, where the car of each cons is an object on the clipboard and the cdr is one of the symbols :text, :rich-text, or :pixmap indicating the Windows clipboard format of that object. The default method does nothing, so an application could simply replace it with a primary method specializing on t, or add an :after method specializing on t.
