[Haskell-cafe] Re: Why binding to existing widget toolkits doesn't make any sense

CSS is purely declarative in nature and entirely deterministic. Moreover, it's expressive power is such that you can completely and radically alter the look of a website with modifications to CSS alone (see Zen Garden). The grammar and semantics are relatively simple and can be interpreted and generated by tools, which means that a designer can work with CSS files without knowing anything about CSS. Is it perfect? No. But it's a lot better than trying to encode everything in a single language that only a software developer can safely work with. Regards, John A. De Goes N-BRAIN, Inc.

Oh, I missed the "like" word! What do you mean with that? What aspects of CSS do you prefer to? In WPF a "style" is basically just a bunch of attribute key/value pairs.

Layout combinators in the spirit of TeX or Lout are more flexible while being simpler. In any case, a simple primitive

grid :: [[Rect a]] -> Rect a

that arranges widgets in a rectangular grid should be enough for GUIs.

Spoken like a true programmer who knows nothing about usability. :-)

Yes, layout must be very versatile and user definable.
