Hi,
this post might be helpful.
http://snipplr.com/view/17538/wxhaskell-multithread--custom-event-example/
I needed something similar and came up with this. As far as I know there
is now wxhaskell internal way of doing this.
import Graphics.UI.WX
import Graphics.UI.WXCore
import Control.Concurrent
eventId :: Int
eventId = wxID_HIGHEST + 2
main :: IO ()
main = do
chan <- newChan
forkIO $ externalEventLoop chan
start $ gui chan
externalEventLoop :: Chan String -> IO ()
externalEventLoop chan = do
writeChan chan "foobar"
threadDelay $ 10 ^ 6
externalEventLoop chan
gui :: Chan String -> IO ()
gui chan = do
vCmd <- newEmptyMVar
f <- frame []
st <- textCtrl f []
forkIO $ eventLoop eventId chan vCmd f
evtHandlerOnMenuCommand f eventId $ takeMVar vCmd >>= \text ->
appendText st $ text ++ "\n"
set f [layout := fill $ minsize (Size 100 100) $ widget st]
eventLoop :: Int -> Chan String -> MVar String -> Frame () -> IO ()
eventLoop eventId chan vCmd f = do
content <- readChan chan
putMVar vCmd content
e <- commandEventCreate wxEVT_COMMAND_MENU_SELECTED eventId
evtHandlerAddPendingEvent f e
eventLoop eventId chan vCmd f

Thanks Michael
Having this in stack.yaml
extra-deps:
- gtk-0.14.2
# Override default flag values for local packages and extra-deps
flags: {
gtk: {
have-quartz-gtk: true
}
}
and adding gtk to cabal file helped me to resolve this issue!
I still have different problem. I will try to find the solution or ask
later when I'm out of ideas.

A search on Internet for the message "dyn is not in $(GhcLibWays)" lead me
