4 Dynamic Loading
The racket/gui/dynamic
library provides functions for dynamically accessing the Racket
GUI toolbox, instead of directly requiring racket/gui or
racket/gui/base.
Returns #t if dynamic access to the GUI bindings are
available – that is, that the program is being run as a
GRacket-based application, as opposed to a pure
Racket-based application, and that GUI modules are attached
to the namespace in which racket/gui/dynamic was
instantiated.
This predicate can be used in code that optionally uses GUI elements when they are available.
(gui-dynamic-require sym) → any |
sym : symbol? |
Like dynamic-require, but specifically to access exports of
racket/gui/base.
