;;; Wishlist items (from widget.texi):
;; * The `menu-choice' tag should be prettier, something like the
;; abbreviated menus in Open Look.
;; * Finish `:tab-order'.
;; * Make indentation work with glyphs and proportional fonts.
;; * Add commands to show overview of object and class hierarchies to
;; the browser.
;; * Find a way to disable mouse highlight for inactive widgets.
;; * Find a way to make glyphs look inactive.
;; * Add `key-binding' widget.
;; * Add `widget' widget for editing widget specifications.
;; * Find clean way to implement variable length list. See
;; `TeX-printer-list' for an explanation.
;; * `C-h' in `widget-prompt-value' should give type specific help.
;; * A mailto widget. [This should work OK as a url-link if with
;; browse-url-browser-function' set up appropriately.]

;;; The `lazy' Widget.
;;
;; Recursive datatypes.
(define-widget 'lazy 'default
"Base widget for recursive datastructures.
The `lazy' widget will, when instantiated, contain a single inferior
widget, of the widget type specified by the :type parameter. The
value of the `lazy' widget is the same as the value of the inferior
widget. When deriving a new widget from the 'lazy' widget, the :type
parameter is allowed to refer to the widget currently being defined,
thus allowing recursive datastructures to be described.
The :type parameter takes the same arguments as the defcustom
parameter with the same name.
Most composite widgets, i.e. widgets containing other widgets, does
not allow recursion. That is, when you define a new widget type, none
of the inferior widgets may be of the same type you are currently
defining.
In Lisp, however, it is custom to define datastructures in terms of
themselves. A list, for example, is defined as either nil, or a cons
cell whose cdr itself is a list. The obvious way to translate this
into a widget type would be
(define-widget 'my-list 'choice
\"A list of sexps.\"
:tag \"Sexp list\"
:args '((const nil) (cons :value (nil) sexp my-list)))
Here we attempt to define my-list as a choice of either the constant
nil, or a cons-cell containing a sexp and my-lisp. This will not work
because the `choice' widget does not allow recursion.
Using the `lazy' widget you can overcome this problem, as in this
example:
(define-widget 'sexp-list 'lazy
\"A list of sexps.\"
:tag \"Sexp list\"
:type '(choice (const nil) (cons :value (nil) sexp sexp-list)))"
:format "%{%t%}: %v"

;; datastructures. This is slow, so we should not create speed
;; critical widgets by deriving from this.
