I see... You need `get-client-handle', which returns the inner widget of a window rather than the outer one. (There are two layers to a `panel%' for event-handling reasons.)
I've added `get-client-handle' to `window<%>', which you should use in this case instead of `get-handle'. Also, don't forget to use `gtk:widget-show'. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
