Some follow-up to my previous message (which, I guess, everyone was waiting
for given the seemingly large interest :)
I tried using quickscript to get access to the interaction window and add
the snip from there and it works.
I feel that this might confirm my hypothesis regarding not being in the
right event space but I could use some help here.
The quickscript script I used:
#lang racket/gui
(require quickscript/script)
(define (show-dialog)
(define f (new dialog% [label "Dialog"] [style '(close-button)]))
(define m (new message% [label "Clicked"] [parent f]))
(send f show #t))
(define (make-snip)
(define t (new text%))
(send t insert "Click Me!")
(send t set-clickback
0 (send t last-position)
(lambda (t s e)
(show-dialog)))
(define s (new editor-snip% [editor t]))
s)
(define-script inspector
#:label "inspector"
(λ (selection #:interactions i)
(send i insert (make-snip))
#f))
Regards
Philippe
