hi, im working ona project, and im having problem loading some code in
wxhaskell:
onOpen :: Frame a -> TextCtrl b -> MenuItem c -> StatusField -> IO ()
onOpen f sw mclose status = do mbfname <- fileOpenDialog f False True "Open
image" fileTypes "" "" case
(mbfname) of (Nothing) ->
return ()
(Just (fname)) -> do
fileContent <- readFile fname
set sw [text := fileContent]
set mclose [enabled := True]
set status [text := fname]
return ()
i keep getting the error : "the last statement in a 'do' construct must be an
expression."
ive tried rearranging it many times, but i still get the same error. any help
would be greatly appreciated.
