I'm glad to see the recent flurry on the GUI mailing list. I think what is now going on is this: We're trying to build a critical-mass of effort and commitment behind one GUI binding NOT to exclude other approaches (because diversity is good) but rather to have enough smart people co-operating that there is some chance that programs written against this API/binding have some chance of working on a variety of platforms (a particularly tricky issue with GUIs) and a variety of Haskell implementations and stay working over a period of time GUIs have very wide interfaces, so doing anything viable is a lot of work. Doing it for lots of platforms is even more work. A big advantage of the Wx approach is that it lets us piggy-back on a much larger effort that has very similar multi-platform goals. Wx isn't perfect -- the Mac menu bar thing seems a case in point -- but at least the Wx crew have exactly the same problem, so there is reason to suppose that the situation may improve. And it does seem to be good enough; by which I mean that it would be hard to improve on, given our effort budget. It's definitely the case that we don't want to program in Wx directly. As Daan mentions, he already has a draft Haskell-ised version of the API, whose design has been discussed quite a bit on this list, and which shares a lot in common with Krasimir's approach. I have the impression that the broad design of the Haskell-ised layer are acceptable to pretty much everyone. But I'm sure Daan wouldn't regard them as cast in stone. As a consumer of this work, my earnest hope is that several smart and productive people will be prepared to work together on the design, implementation, and multi-platform porting of a Hakellised WX interface; and on doing a forest of related projects (port Fudgets, make GUI builder...). Although Daan has done great work getting this Wx stuff started, it's too big a job for one person even if he did nothing else (and Daan is far from being in that position). And again as a consumer, I feel much more confident in using something that has a wide support base rather than something that depends critically on one person. There are many very talented people contributing to this discussion (in no particular order, Nick Name, Wolfgang Thaller, Axel Simon, Krasimir Angelov, David Roundy, Wolfgang Jeltsch, Manuel Chakravarty, Daan Leijen, David Sankel, Anthony Courtney, George Russel, Peter Aachten, Adrian Hey, John Meacham, to name only recent contributors). Let's hope that from this mix, enough of a critical mass will emerge to make this really work. Simon
