Is the dc% that is passed to the paint-callback for a canvas always the same dc% returned by (send canvas get-dc)? In other words, are the following equivalent?
[paint-callback (lambda (canvas dc) (send dc clear))] [paint-callback (lambda (canvas dc) (send (send canvas get-dc) clear))] Justin ____________________ Racket Users list: http://lists.racket-lang.org/users
