Ok, so that means there?s nothing to be done for now, I just have to wait ?
Some other small questions, not directly related:
I?m using leksah to edit code. How do I:
- Browse the source of reactive-banana from leksah ? I would like to check for
instance how the Applicative of Behaviour is implemented.
- Is it possible to check the type of statements from the gui ?
- Is it possible to pull up the documentation of a function directly from the
gui ?
- Is it possible to to the definition of a function, including the ones in
other packages (like the ones of reactive-banana) directly from the gui ?
thanks !

Not sure if I was suppose to try with that command, but If I do I get:
miguelnegrao@Mac-Miguel:~/Development/Haskell/Libs/reactive-banana/reactive-banana-wx
(master *)$ cabal install -fbuildExamples

Also wxHaskell seems to be properly installed since I can run the hello world
app.

Ok, by deleting all the examples I managed to install reactive-banana-wx. The
Couter.hs example runs fine.
I?m now trying to do a example where the value of a slider is posted to text
box, but I can?t get it to work. event0 is for events that don?t ouput
anything, but slider has a value.... what should I do ?
{-----------------------------------------------------------------------------
A slider and a text box
------------------------------------------------------------------------------}
{-# LANGUAGE ScopedTypeVariables #-} -- allows "forall t. NetworkDescription t"
import Graphics.UI.WX hiding (Event)
import Reactive.Banana
import Reactive.Banana.WX
{-----------------------------------------------------------------------------
Main
------------------------------------------------------------------------------}
main:: IO()
main = start $ do
f <- frame [text := "A slider"]
sl <- hslider f False 0 100 []
output <- staticText f []
set f [layout := margin 10 $
column 25 [widget sl, widget output]]
let networkDescription :: forall t. NetworkDescription t ()
networkDescription = do
esl <- event0 sl command
let b = stepper 0 esl -- this doesn?t work off course...
sink output [text :== show <$> b]
network <- compile networkDescription
actuate network
thanks

Errm, reactive-banana-0.6.0.0 is the current development branch which is
definitely not going to compile. I meant the tarball from hackage, i.e.
http://hackage.haskell.org/packages/archive/reactive-banana-wx/0.5.0.0/reactive-banana-wx-0.5.0.0.tar.gz

You can use fromPoll as the NetMonitor.hs examples demonstrates. Or
you have to get an event from wx that indicates when the slider is
moved, then you can use stepper or the fromChanges function.
