Summary

Returns the primary selection.

Package

capi

Signature

selection self &optional format => result

Arguments

`self`⇩	A displayed CAPI pane or interface.
`format`⇩	A keyword.

Values

result

A string, an image, a Lisp object, or nil.

Description

The function selection returns the contents of the primary selection as a string, or nil if there is no selection.

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.

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

On Microsoft Windows there is no notion of selection, so this mechanism is internal to Lisp.

Note that X applications may or may not use the primary selection for their paste operations. For instance, Emacs is configurable by the variable interprogram-paste-function.
