Hi,
It seems that clickbacks are not working when a snip is displayed in
DrRacket interaction window.
Here is a sample program:
#lang racket/gui
(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 f (new frame% [label "Test"] [width 300] [height 200]))
(define e (new text%))
(define c (new editor-canvas% [parent f] [editor e]))
(send f show #t)
(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]))
(send e insert s)
If you click on the Click Me text you will get the dialog displayed.
If I enter 's' (without the quotes) in DrRacket interaction window, I can
see my snip displayed but clicking on it does nothing.
I looked at DrRacket code but did not find anything that makes me think it
should not work except, maybe, for the fact that the snip is sent using the
text:send-snip-to-port function which serializes the snip to the proper
event space using text:make-snip-special.
Could someone enlighten me on why it is not working as I expect and how I
could make this works ?
Thanks for your help
Philippe
