Re: Android REPL - add* syntax-sugar not available in constructor

[teyc <teyc at cognoware dot com>]

Thank you. I used the latest svn sources and I'm now able to use the addXXX
in constructors. It works very well for specifying layout.

The following works on the REPL:

(*activity*:runOnUiThread
  (runnable
    (lambda ()
      (try-catch
        (*activity*:setContentView
          (android.widget.LinearLayout *activity*
            orientation: android.widget.LinearLayout:VERTICAL
            view: (android.widget.TextView *activity* text: "Hello")
            view: (android.widget.Button *activity* text: "Click")))
        (e java.lang.Exception
          (android.util.Log:v "kawa-hello" e))))))

Unfortunately, I couldn't attach any event handlers from the REPL, as
the following fails with "this expression must be compiled, but compiler is
unavailable"

(*activity*:runOnUiThread
  (runnable
    (lambda ()
      (try-catch
        (*activity*:setContentView
          (android.widget.LinearLayout *activity*
            orientation: android.widget.LinearLayout:VERTICAL
            view: (android.widget.TextView *activity* text: "Hello")
            view: (android.widget.Button *activity* text: "Click"
                   on-click-listener: 
                     (lambda (v) ((android.widget.Toast:makeText *activity*
"Clicked Me" andoird.widget.Toast:LENGTH_LONG):show))))
        (e java.lang.Exception
          (android.util.Log:v "kawa-hello" e))))))

Is this is hard limitation, since kawa has to generate an anonymous class on
the fly to handle the event?

Is there anyway I can use a precompiled MouseAdapter class that would invoke
a closure? I tried something like the following:


; a job that is posted on a UI thread.
(define-simple-class Job (java.lang.Runnable)
    (result type: java.lang.Object init-value: #!null)
    ;((*init*) #!void
    ;   (display "Init Job"))
    (form init-keyword: form:)
    ((*init* (form0 :: java.lang.Object))
        (set! form form0))
    ((run) :: #!void
        (synchronized (this)
            (if (not (eq? #!null form))
                (set! result (eval form (interaction-environment))))
            (sleep 2.0)
            (notify))
    ))

but the verifier didn't like it (perhaps the code is too dynamic?)
