@defmodule[scheme/gui/dynamic]{The @schememodname[scheme/gui/dynamic]
|
|
library provides functions for dynamically accessing the PLT Scheme
|
|
GUI toolbox, instead of directly requiring @scheme[scheme/gui] or
|
|
@scheme[scheme/gui/base].}

@defproc[(gui-available?) boolean?]{
|
|
|

Returns @scheme[#t] if dynamic access to the GUI bindings are
|
|
available---that is, that the program is being run as a
|
|
@exec{mred}-based application, as opposed to a pure
|
|
@exec{mzscheme}-based application, and that GUI modules are attached
|
|
to the namespace in which @scheme[scheme/gui/dynamic] was
|
|
instantiated.
|
|
|
|
This predicate can be used in code that optionally uses GUI elements
|
|
when they are available.}

Like @scheme[dynamic-require], but specifically to access exports of

@scheme[scheme/gui/base].}
