Description

The function clipboard returns the contents of the system clipboard as a string, or nil if the clipboard is empty.

format controls what kind of object is read. The following values of format are recognized:

:string
The object is a string. This is the default value.
:image
The object is of type image, converted from whatever format the platform supports.
:value
The object is the Lisp value.
:metafile
The object is a metafile.

When format is :image, the image returned by clipboard is associated with self, so you can free it explicitly with free-image or it will be freed automatically when the pane is destroyed.

When format is :metafile the object is a metafile which should be freed using free-metafile when no longer needed. See also draw-metafile and draw-metafile-to-image. format :metafile is not supported on GTK+ or X11/Motif.

The Microsoft Windows clipboard is usually set by the user with the Ctrl+C and Ctrl+X gestures. Note that the LispWorks editor uses these gestures when in Windows emulation mode.

On X11/Motif, various gestures may set the clipboard. Note that LispWorks uses Ctrl+C and Ctrl+X when in KDE/Gnome editor emulation mode. The X clipboard can also be accessed by running the program xclipboard or the Emacs function x-get-clipboard.

The macOS clipboard is usually set by the user with the Command+C and Command+X gestures.
