I managed to write my first Haskell program with a GUI! It shows a window
of sliders and when you move a slider it sends an according MIDI
controller message via ALSA.
http://code.haskell.org/~thielema/alsa-gui/
Now I like to provide the reverse direction: If my program receives a MIDI
I wanted to have a vertical slider with small numbers at the bottom and
large numbers at the top. To this end I implemented a variant of
'vslider' that automatically inverses its direction, if the bottom value
is smaller than the top value. You may like to replace the current
'vslider'

Dear all,
in wxHaskell (core) I can set and get event handlers
http://hackage.haskell.org/packages/archive/wxcore/0.12.1.7/doc/html/Graphics-UI-WXCore-Events.html
but how is it possible to create events
Sometimes I forget to enclose a WX-GUI in WX.start, now I have a case,
where WX.start was called twice at different places.
How about putting the WX commands in a separate monad and give WX.start
the signature:
WX.start :: WX a - IO ()
?
Recently on this list it was suggested to use
myEventId = wxID_HIGHEST+1
for custom events and register them as menu events.

The original question still stands: is it worth exposing this sort of
wxcore documentation [1] says:
textCtrlGetSelection :: TextCtrl a -> Ptr b -> Ptr c -> IO ()
Is this correct? I assume b and c should be CInt.
