[racket] Racket gui

Hello,

Most of the GUI is defined in the directories starting at <racket
installation directory>/collects/mred.

I'm not sure what kind of extensions you're looking at doing, but the
frame% class is defined in collects/mred/private/mrtop.rkt.

And you would extend (sub-class) this and the other GUI classes in the
normal way, e.g.

(define my-frame%
  (class frame%
    (init [my-init-field <some default value>])
    ; other definitions etc
    (super-new)
    (define/public (new-method x y z)
      ; my-method implementation
      )
    (define/override (old-method x y z)
      ; override implementation
      )
    ; other definitions etc.
  ))

(define f (new my-frame% [my-init-field <some value>] ... ))

(send f show #t)

Hope this helps,

Kieron.
