10 Dynamic Loading
The racket/gui/dynamic
library provides functions for dynamically accessing the
racket/gui/base library, instead of directly requiring
racket/gui or racket/gui/base.
Returns #t if dynamic access to the GUI bindings is
available. The bindings are available if
racket/gui/base has been loaded, instantiated, and
attached to the namespace in which racket/gui/dynamic was
instantiated.
(gui-dynamic-require sym) → any sym : symbol?
Like dynamic-require, but specifically to access exports of
racket/gui/base.
