I prefer the elegant high-level style of wxhaskell over the current state of gtk2hs. duncan has said he's interested in making a gtk2hs more elegant, and daan has said he'll start supporting wxhaskell again. i don't know which will happen first. - Conal On Dec 12, 2007 11:47 AM, Neil Mitchell wrote:

Hi

...

Is there any really cross-platform GUI library for Haskell?

Gtk2Hs is good (I suppose), but it requires X. OK, I have X, but it's not "native" on my Mac; some Mac users don't install it and almost all Mac users don't always run it.

On Windows, Gtk2hs is not as native as wxHaskell, but is the best GUI toolkit available. On Windows, there is no requirement to have X installed. The Gtk2hs developers (or more specifically Duncan) have shown a continuing desire to make Gtk2hs more Windows friendly, even to the point of filing Gtk bugs and tracking their progress. I'm sure having made Mac friendly noises, they will come rushing to your aid :-)

Thanks

Gtk is going native on Mac: http://developer.imendio.com/projects/ gtk-macosx .

Huh. I found the sourceforge project, which seems to have died in 2003; this looks a bit more hopeful. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH

I've seen an Objective C binding for Haskell; haven't used it yet. 13.12.2007, в 2:58, Marc A. Ziegert писал(а):

the problem is Apple. if you want to have a native gui on OSX then you are either nearly stuck to Objective-C or to obsolete gui libraries. i'm not a mac user, but i know one who is; he told me. on osx there are two main gui apis: carbon and cocoa.

carbon is obsolete, but it partially runs on osx -- it is not 64bit compatible. http://en.wikipedia.org/wiki/Carbon_%28API%29

cocoa is the newer one, which every mac user likes. AFAIK there is no C backend to that api, so you will have to develop a C backend first and then the haskell (or gtk2) wrapper. there are some bindings for other languages, i.e. C#, but no C. http://en.wikipedia.org/wiki/Carbon_%28API%29

if you are able to code objective-c and know how to access cocoa using c, please help those gtk developers to port gtk2 to native OSX. it will then automagically work with gtk2hs.
