Hi: I'm new to Haskell and to wxHaskell (but found playing with wxHaskell to be a nice mid-ground between my years of imperative experience and the pure functional). Thanks for the help. I wrote the following code to create a set of staticText widgets by mapping the layout over a list. Easy enough... module Main where import Graphics.UI.WX main :: IO () main = start gui gui :: IO () gui = do f <- frame let s = map (\t -> staticText f [text := show t]) [1..10] set f [layout := margin 10 ( row 2 $ map (\x -> (widget x)) s)] But, I get a type error that I do not understand Couldn't match expected type ‘IO (Window a0)’ with actual type ‘[Prop (Frame ())] -> IO (Frame ())’ Probable cause: ‘frame’ is applied to too few arguments Thank you in advance, Jason
