[wxhaskell-users] type safe handling of flags
I don't know whether I proposed it already ...
I wrote a package called enumset. It provides low-level bitsets like they
are used by wxWidget. The definition is essentially:
newtype EnumSet storage index = EnumSet storage
E.g. with
data Style = Bold | Italic | Underlined deriving (Enum)
the type (EnumSet Word32 Style) represents a subset of {Bold, Italic,
Underlined} stored as a bitfield in a Word32.
http://hackage.haskell.org/packages/archive/enumset/0.0.4/doc/html/Data-EnumSet.html
The other modules can be used to manage bitfields where not individual
bits must be processed, but there are groups of bits, where each group
represents a value.

[wxhaskell-users] Fwd: UI updates from non-UI threads: an addition to wx?
Including wxhaskell-users. Anyone interested in async UI update functionality? Cheers, Maciek -- Forwarded message -- From: maciek.makow...@gmail.com Date: Fri, Aug 24, 2012 at 10:41 PM Subject: UI updates from non-UI threads: an addition to wx? To: wxhaskell-devel wxhaskell-de...@lists.sourceforge.net Getting wxHaskell to handle UI updates from non-UI threads was a frustrating experience; it's embarassing how long it took me to realise that the solution presented in this StackOverflow answer: http://stackoverflow.com/a/3182588/424978 is probably the only viable one. I've packaged it into a tiny module that provides Gtk2hs-style `postGUIAsync` function: https://github.com/mmakowski/habaz/blob/master/src/Graphics/UI/WX/Async.hs. Is there any interest in incorporating this into wxHaskell proper? It might save other users some head scratching.
