Arguments: lisp-edit-pane file-position type matches-closing in-view
This generic function is called whenever the text cursor in a lisp-edit-pane is
moved so that it is just before an opening parenthesis or just after a
closing parenthesis, if there is a matching parenthesis within the
top-level lisp form that the text cursor is in. It is also called for
matching double-quote characters of literal strings.
There is no need for an application to call this function, but it may
add methods to implement side effects. A lisp-edit-pane will automatically
draw a mark to indicate the matching parenthesis if it is in view
(according to parenthesis-matching-style and
parenthesis-matching-color), but an
application may also wish to add a status-bar message, for example,
particularly if the matching parenthesis is not in view.
The default method that specializes on lisp-edit-pane does nothing. (The
IDE editor adds an internal method to its lisp-edit-pane subclass for
status-bar messages.)
The method will be called with the following arguments:
lisp-edit-pane window where the
parenthesis match has occurred.
nil for a
matching parenthesis or the keyword :quote for a
matching double-quote character.
nil if
it is an opening one.
nil
otherwise.
