Wrong indentation. Tab stops are 8 spaces in Haskell, but your code seems to assume 6 spaces.

------------------------- module Main where

import Graphics.UI.WX

main :: IO () main = start hello

hello :: IO () hello = do f <- frame [text := "Super Window"] lab <- staticText f [text:= "Hello"]

The 'lab <-' actually lines up with 'frame', not with 'f <-' as intended. Regards, Malcolm

Sorry for interuption. In some days later, I have to work with Graphs.UI, too. So I tried to run your example below, but I met a compiled error Prelude> :load graph.hs Reading file "graph.hs": Reading file "Graphics.UI.WX": ERROR "Graphics.UI.WX" - Unable to open file "Graphics.UI.WX" I guess the error happened because my hugs (and ghci) do not have WX, or I do not give some options to the command for compiling. Is it right ? Thank you for your consideration. On 11/28/05, mempko wrote:

set f [layout:= floatCenter (widget lab) $ floatCenter (widget touch) $ floatCenter (widget quit)]
