If you have figured it all out, I hope you want to write a HaskellWiki  

page about it.

If I pass the gating, I ll publish a kind some HowTo on the differente techniques I dig out

already started with this one, where I published my finding in the answer:

http://stackoverflow.com/questions/15867654/wx-haskell-drag-and-drop-example 

As no one else has responded so far, I think you are in uncharted  

territory; wxHaskell is huge and there are not many applications using it.  

good point. ! 

do we have some kind of census of application that wrok or still work with wxhaskell ?

any interest in (me) doing this ? (who know some toosl to do this, a la doodle ?)

and by extension : 

btw how many people are really active and resonably knowleadeable these day ? (e.g. "senior")

Are Eric ? Jeremy ? atzedijkstra ? yourself ? still active on wx.

and are you using it yourself HenkJan ?

is :    https://github.com/atzedijkstra/wxHaskell 

the head dev for these day ?

i.e. who is the maintainer ?

( Sorry for all these questions, but I am just discovering the field :-)
