[wxhaskell-users] wxHaskell and threads: FAQ is still best advice?

[Andy G. <ha...@gi...>]

Hi all,

I just wanted to ask whether the FAQ entry on multiple threads at

http://haskell.org/haskellwiki/WxHaskell/FAQ

is still the best advice?  It mentions GHC 6.0, but I wondered if  
things had changed since then.

Thanks!

So, I don't know much about this kind of stuff

But it looks like you could get some insights from

  http://docs.wxwidgets.org/stable/wx_wxthreadoverview.html#wxthreadoverview

Note also that the Process sample has not changed since the last commit
from Daan.  Maybe you could try compiling it?

I also noticed

Yeah, I spotted that, and for now the plan is to use the idle event  
and split my long-running operation into tiny chunks, called  
repeatedly by that.  It's not very satisfying but I guess it will work.

I did; it compiles, and works nicely, yes.  But I don't want to launch  
external processes, which is what that part of the library seems to be  
about?

I'd seen that too, but not looked too closely because it didn't appear  
to be so relevant. Maybe I should look more closely at  
evtHandlerProcessEvent and friends, then.

Thanks!

Well, I suspect the external processes bit is just an excuse to have
a separate thread running.

If you could update the wiki with your experiences, that would be a big
help.

Thanks!
