No comment on the order of the points (I don't know this stuff too
well). Is this related to wxWidgets perhaps? Maybe it's the underlying
functionality that wants it that way.

Could you check with the darcs version of wxhaskell? I recall something
like this having been fixed.

Plus, here's what it looks like on my end (the colours are weird because
of a bug (maybe) on MacOS X; and there are two triangles because I added
before and after code).

You might encounter some pain installing the new wxhaskell, in that now
you need a version of wxWidgets with Unicode _enabled_, and not 2.8
either, as wxhaskell does not seem ready for it yet.

[wxhaskell-users] drawPolygon

[Daniel J B. <dan...@ya...>]

Hi,

I'm confused about how drawPolygon works; or rather in my case
doesn't. I can draw a triangle (Polygon [pt 50 175, pt 100 0, pt 0 0])
but the points have to be in that exact order or it won't work.
Furthermore if I try to translate all the points by, for example,
10i+10j when I draw it not all the points have been translated. See
here for what I mean: http://omploader.org/vMTdu with the code listing
here if you want it: http://hpaste.org/1998

Why not? Can't this be promoted to the "official windows version"? It
seems the problem I've been complaining about has been solved modulo
alpha renaming!

We have full control of the wxhaskell homepage (it's in the darcs repo),
so couldn't we at least update the official build instructions?

Yes, I'm Windows developper and I put a few version of Windows installer
on my project( Kamiariduki)'s file space.

http://sourceforge.net/project/showfiles.php?group_id=168626


But ... there is a problem.
First, it's not official release.

People search binary file for wxHaskell's website first, and if they
don't get any imformation that, many of probabry give up to use wxHaskell.

Some people try to build wxHaskell, but sadly this is not easy task.
Because wxHaskell site's Building Guide is out of date.
Okay, we have another imformation on Haskell.org, but this is not
easy to reach there.

http://www.haskell.org/haskellwiki/WxHaskell/Install

Some people reached unofficial release fortunately. (This is very
difficult. Because there is no link from official pages.) But it's
just unofficial release, so they can't expected to get binary as soon
as new GHC is released or solving building problem (if that is occur).

SourceForge don't accept same name. So I don't want to put new binary,
if anyone donesn't say problem. I want to hold name to use more better
patched version (e.g. version of supporting more wxWidgets' feature).

I think unofficial release must make good the shortage for official
release, not release constantly instead of releasing official one.

Yep! I didn't feel any acrimony in your mail.  Was forwarding it because I

Indeed.  In Jeremy's 'Reviving wxHaskell' mail, we had fixed some modest
objectives, which were

Well, we got that working for wxWidgets 2.6, but this is a moving target
and now it no longer compiles with 2.8.  There is a hack floating around
on the net which consists of using 2.4 compatibility and telling wxhaskell
that really it's compiling against 2.4.  Not sure that's the right way to
go about it though.  Alas, we are moving more slowly than our target.

>> * Add Eric Kow's Unicode patches (exist today)

Check.  Unfortunately, I have not been able to back this up with any
rigourous testing.  Just a little demo program in the samples directory.

I think we'd better ditch this objective and just focus on getting this

I just want to make it clear than I appreciate the work that has been
done with wxHaskell, and indeed, it was the first Haskell GUI I
started using. I have no particular desire for wxHaskell to be
extended, but because every successive version of GHC is incompatible
with the binaries, it is essential (in my opinion) that each GHC
release has a corresponding wxHaskell Windows binary.

I'm guessing that the job of producing a Windows installer is fairly
easy, given the right build setup. Is there no Windows wxHaskell
developer who is in a position to do this?

Hi wxhaskellers,

Just forwarding a comment from Neil on Haskell Caf=E9.  He has expressed a
similar sentiment on #haskell a long time ago (which I think I have
relayed as well).

For the record, my participation in this project consists of reviewing
incoming patches (if nobody else does), and pushing them to darcs.  To
be honest, I'm stretched too thin for even this meager job.  Luckily,
there have not been any patches for a while :-/.

That said, I think wxhaskell is really handy.  I like having a native
GUI on every major platform (may not be perfect, but is a good
compromise) and I like the relatively high level library.  So it would
be *really* nice to keep this project alive.  I'll bet other users on
this list agree with this sentiment.

Jeremy and friends: anybody still have time to be working on this?  And
wxhaskell-users, are any of you willing to step up and take over the
patch review job?

Thanks!

Sounds like it's Unicode-related.  The darcs version of wxhaskell wants
a unicode-enabled wxWidgets underneath.

Sorry!  I wasn't thinking about that when I suggested the upgrade.

[wxhaskell-users] wxHaskell doesnt show windows correctly

[Patrick S. <pa...@yo...>]

Hi again,

after compiling the darcs version, wxHaskell seemed to work.
But something is wrong with the fonts. I don't see any menu entries 
but they seem to be there because I can click on them and they pop
open. The title bar of the wx windows only show the first letter of the
full name. For instance the bouncing ball demo works fine except that I
don't see any text (ok.. the "B" in the title bar).

Can anyone figure out where this comes from? The ghc compiles without
warning or error. 

I compiled successfully the treectrl.cpp from wxwindows and it looked
fine. It looked as fine as my gimp which uses the gtk.
Is there anything more I can do?

Cheers
 Patrick

But now I've discovered that using "-optl-mwindows" creates a program

I heard that wxHaskell can build with wxWidgets 2.8.0.
http://caml.inria.fr/pub/ml-archives/caml-list/2007/01/d40b2a810ca50f63456508cf57d418cc.en.html

But we can't see his solution, so I just point out my ideas.


If you want to build wxHaskell with wxWidgets 2.8.x, you must build wxWidgets
with "#define WXWIN_COMPATIBILITY_2_4 1" at least.

Because wxHaskell requires to build on wxWidgets 2.4.2, so wxHaskell uses
deprecated wxWidgets 2.4's API.

And what is a platform that you are using? If you don't use Windows or
PowerPC Mac, I think you must use just --enable-compat24 option to build
wxWidgets 2.8.x. But you use these platform, you must worried care about
more detail.

Another solution is use wxWidgets 2.6 API, if wxHaskell build with higher
2.6.x version by #ifdef macros like wave.cpp.
Does anyone already try to add supporting wxWidgets 2.6 or 2.8 API?

In that case, you only need to modify your code a little, to move the

change last two lines to:
   eval   <- button p [ text := "Process"
                      , on command := do mytext <- textCtrlGetValue stxt
                                         logMessage mytext ]
