Yes. Yes, that exactly solves my problem. *sheepish look* Thanks.

When you write
(mixin (drracket:unit:frame<%>) (drracket:unit:tab<%>)
;; body
...)
This produces a function that takes classes which implement the
drracket:unit:frame<%> interface and produces classes that implement the
drracket:unit:tab<%> interface. In the body of the mixin you can only

This is the change to DrRacket:

The lack of newlines is probably because of a bug that I pushed a fix
for. Maybe try a shapshot build?

Hi,
Just for the sake of completeness.
In constructor-style-print.rkt, I've switched on the printing of booleans as
"true" and "false" as follows (editing line 14):
;; print-convert/constructor-style : Any -> Any
(define (print-convert/constructor-style v)

The Documentation talks about range of classes, and I am not really sure what
that means.
Above would then be everything between frame and tab? But why cant I then not
use frame functions in the implementation?

Sean,
Thanks for the encouragement and offer.
Ironically, *I* wouldn’t be able to access them from the office, since
I’d have to -- guess what -- go through a proxy to reach them! You,
of course, are welcome to try. And tell me if it doesn’t scratch your
itch in any way.

Hi Tim,
This is great, the whole proxy thing has been an issue for me as well - I took
a stab at doing something like this last year but couldn't get it working.
I have access to a trend and scansafe proxy so can physically test against
those if you want.
Kind regards,
Sean

I really like Racket although I haven't used it much. It's a shame it isn't
more popular, maby a new slogan would make it better. I don't think "A
programmable programming language" is very catchy, "Batteries included" might
be a better option.
I'm planing to make a CAD in Racket, I have done
19 matches
