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.
