Re: [wxhaskell-users] Building on Windows 7

[Jeremy O'D. <jer...@gm...>]

Hi Dan,

I have confirmed the problem exists, but it's really a Haskell
Platform (rather than Windows 7)issue - the latest Haskell
Platform doesn't include C++ support. Workaround is to use the
previous Haskell Platform version. I'm posting to Haskell list to
see if there's a work-around.

Regards
Jeremy

the one that comes with the haskell platform because the latter

Thanks

Re: [wxhaskell-users] Building on Windows 7

[Jeremy O'D. <jod...@fa...>]

Hi Dan,

I don't know of anyone who has done this. I have a 64 bit Windows 7  
machine at work which has never had wxHaskell on it (in fact, it  
hasn't had Haskell at all!), so I'll try a clean build in the next  
day or two and let you know what happened (I'll be using the latest  
Haskell Platform as my ghc install). If I run into any issues it may  
take me a few days to fix them, but if all is smooth, I'll document  
exactly what I did (if it differs in any way from the wiki).

Ghc includes its own copy of MinGW, so I don't think it's a good idea  
to point to the libraries from your own installation. However, if  
there's any issue, I'll hopefully find it very soon.

Regards
Jeremy

Re: [wxhaskell-users] wxcore error on ubuntu

Hi Sok,

I'm afraid this is a known issue for which I do not yet have a fix.  
Currently wxHaskell is not usable from ghci, I'm afraid.

[wxhaskell-users] Building on Windows 7

[Dan H. <dev...@gm...>]

I have been trying to build the latest version on windows 7 for a few days
now. I have not managed to get it. The furthest I have gotten has given me
an error-dump from cabal about /include/wx/string.h after [22 of 22]...
\WXCore.o

I built wx in the way that was prescribed by the wiki page. I then set the
environment variable WXWIN and WXCFG properly. When I tried to run cabal
install wx, it failed telling me I didn't have a long list of C libraries. I
then ran cabal install wx --extra-include-dirs = "" --extra-lib-dirs "" to
point to the libraries in my mingw distribution. I am using my own instead
of the one that comes with the haskell platform because the latter didn't

[wxhaskell-users] Multithreading - The effects of forkIO in wxHaskell

[Fernando B. <gre...@gm...>]

Hi all,
	While developing our project λPage, we've found something we like to  
share with you all.
	We have an application with a main window and we want to update a  
part of the window (in this case, a textbox) while letting the user  
work with the rest of the UI.
	To accomplish that, we need to parallelize things and the natural way  
of doing so is using Control.Concurrent.forkIO.
	So, we have the main thread that handles the UI (like all wx apps do)  
and another one, started with forkIO, that periodically updates a  
textbox using textCtrlAppendText.
	Then we noticed that the forked thread only worked when the user  
*actually* used the UI, i.e. if the user just waited to see the new  
values appear in the textbox, those updates never happened.  But in  
the very instant he moved the mouse or touched a key, BOOM, the  
textbox was updated.
	We found out what was going on and I think Jeremy will explain it  
better than me (maybe as an article in his blog? :P), but the basic  
idea is that the main loop of any wxHaskell application is running in  
C and the wxHaskell functions are only used as callbacks, so once the  
control returns to the C loop it doesn't come back to Haskell world  
until "something happens" (i.e. some event is triggered by the UI).
	We worked around the issue by adding a "keep-alive" timer that ticks  
every 50ms, but that's not the most elegant solution, isn't it?
	Anyway, to prove our point I've developed a tiny example that I'm  
attaching to this mail.  To try it, once compiled and running, use the  
"Actions" menu to start the logger and then start and stop the timer.   
If you do nothing else in the application, you should see that it logs  
only when the timer is ticking.
	I hope this helps as it was really hard to understand and work  
around :)

Re: [wxhaskell-users] embedding web control

Hi Konstantin,

I have started looking at using wxDirect to wrap other wxWidgets
components. Bottom line is that you can't really do it with the

I think you would need to use wxDirect to integrate properly with
wxHaskell. It's a bit tedious, but not especially hard. I'll

what you need to do are as follows:

Create an Eiffel(!) file containing all of the constant

to Eiffel. This requires no real knowledge of Eiffel: it's simply

wxMY_CONTROL_SOME_VALUE : INTEGER is 23

Create a C header file describing the API you want to wrap - this

Run wxDirect over the newly created files - this autogenerates C
wrappers over the C++ classes/functions with appropriate Haskell
to use them.

I realize that this is a bit 'handwaving', but a full description
really requires quite a lot more than I can manage in a single
e-mail.

As a little more help, if you download wxCore source code (cabal
fetch wxcore), you can look at the following files for
inspiration:

wxcore/src/include/wxc_glue.h and wxc.h - these show the
'wrapping' style needed.
wxcore/src/eiffel/stc.e - this shows how to define constants in
the Eiffel format

WxDirect accepts the following options:

-d : create constant definitions from .e files
-c : create class definitions from .h files
-t : create class type definitions from .h files
-i : create class info definitions
-o : set the output directory

Re: [wxhaskell-users] embedding web control

[Jeremy O'D. <jer...@gm...>]

Hi Konstantin,

To answer your first question, frame returns a Frame (), which,
under the hood is an Object  - that's another way of saying that
I think your code is at least correctly typed.

I think you would need to use wxDirect to integrate properly with
wxHaskell. It's a bit tedious, but not especially hard. I'll
probably write a blog posting about this soon, but the basics of
what you need to do are as follows:

Create an Eiffel(!) file containing all of the constant
definitions exported by wxWebConnect (or at least the ones you
want...). The reason for the Eiffel is historical: wxHaskell was
originally built on top of a (long-obsolete) binding of wxWidgets
to Eiffel. This requires no real knowledge of Eiffel: it's simply
a file containing lines such as:

wxMY_CONTROL_SOME_VALUE : INTEGER is 23

Create a C header file describing the API you want to wrap - this
is somewhat stylized, using macros to describe inheritance.

Run wxDirect over the newly created files - this autogenerates C
wrappers over the C++ classes/functions with appropriate Haskell
to use them.

I realize that this is a bit 'handwaving', but a full description
really requires quite a lot more than I can manage in a single
e-mail.

As a little more help, if you download wxCore source code (cabal
fetch wxcore), you can look at the following files for
inspiration:

wxcore/src/include/wxc_glue.h and wxc.h - these show the
'wrapping' style needed.
wxcore/src/eiffel/stc.e - this shows how to define constants in
the Eiffel format

WxDirect accepts the following options:

-d : create constant definitions from .e files
-c : create class definitions from .h files
-t : create class type definitions from .h files
-i : create class info definitions
-o : set the output directory

I suspect that you will have a bit of trouble with getting all of
this to work, so if you can wait (it may be a couple of weeks),
there may be a blog posting to help you.

Jeremy

control can be created (wxButton, wxLabel).
If first parameter to c_browserFrame (parent window) is
objectNull then everything is ok with no changes to gui. I can't
understand what is wrong with ptrWxWindow param when passed from

Re: [wxhaskell-users] embedding web control

[carlos g. <car...@gm...>]

Interesting, but I don't know how to fix. Maybe you can use the wxHtmlWindow
of WxCore, it is an html engine too.
You can see
http://hsbrowser.wordpress.com/2010/04/05/using-wxhtmlwindow-with-wxhaskell/

I hope this help.

[wxhaskell-users] embedding web control

[Konstantin C. <kch...@gm...>]

Hello, wxHaskell community!

I need to embed web control into my application under Windows 7. I am trying
to use wxWebconnect (
http://www.kirix.com/labs/wxwebconnect/documentation/getting-started.html )
library with Gecko engine for this.
Haskell code:
foreign import stdcall unsafe "_browserFrame"
    c_browserFrame :: Ptr a -> IO(Ptr ())

main :: IO ()
main
  = start gui

gui :: IO ()
gui = do
    f <- frame [text := "Hello world!", size := (sz 600 600) ]
    withObjectPtr f c_browserFrame
    return ()

where browser frame looks like
C++ code:
void* __stdcall browserFrame (wxFrame* ptrWxWindow)
{
    wxString xulrunner_path = FindXulRunner(wxT("xr"));
    wxString dir(wxT("\\plugins"));
    wxWebControl::InitEngine(xulrunner_path);
    wxWebControl::AddPluginPath(dir);
    wxWebControl* ptrBrowser = new wxWebControl(ptrWxWindow, wxID_WEB,
wxPoint(0,0), wxSize(600,600)); //Here error comes from
    return ptrWxWindow;
}
it is compiled as dll by MS Visual 2008 and linked to Haskell program.

Also it looks like CreateControl execution fails.
It should be mentioned that ptrWxWindow can be operated with no errors (I
mean hiding, resizing etc) and no any other kind of control can be created
(wxButton, wxLabel).
If first parameter to c_browserFrame (parent window) is objectNull then
everything is ok with no changes to gui. I can't understand what is wrong
with ptrWxWindow param when passed from Haskell.
typeid(ptrWxWindow).name() shows expected type of ptrWxWindow - wxFrame.

What am I doing wrong? Please help me. Or maybe can you help me using your
wxdirect subsystem to add this control to wxHaskell?

with best regards,
Chugalinskiy Konstantin

I can confirm this with wxGTK for what it's worth.

Maybe somebody on Windows/MacOS X should try it and
see what happens?

[wxhaskell-users] GLib-GObject-CRITICAL errors when running WxHaskell app

[Søren H. <sha...@ho...>]

Hi everyone

When compiling this:
http://imada.sdu.dk/~sorenh07/misc/haskell/Turtle.hs

I get many strange GLib-GObject-CRITICAL errors like this:
http://imada.sdu.dk/~sorenh07/misc/haskell/Turtle.hs.out

A simpler program like this:
http://imada.sdu.dk/~sorenh07/misc/haskell/Simple.hs
works just fine.

I don't remember having seen Haskell code come up with a "Segmentation Fault"
before (usually programming errors are caught by the type checker). Is there
anything obvious I'm doing wrong?


Best regards,
Søren

[wxhaskell-users] haskell-platform-2010.1.0.0, MacPorts & wxHaskell works w/ work

[Eric Y. K. <eri...@gm...>]

Hi everyone,

Here's a user report with some good and bad news.  If somebody from
the wxHaskell Team could bless or comment on this, I might forward it
along to Haskell-Café.

I'm Bcc'ing Gregory Wright from the MacPorts team as I think he may
be interested.

First the good: with MacOS X 10.6 (but 32 bit), the new wxHaskell
packages by Daniel Fischer seem to work fine with GHC 6.12 and the
latest Haskell Platform.

And now the bad news: you have to work a little to get there if
you're using MacPorts.

Summary
=======
1. No more MacPorts wxWidgets; build one yourself
2. Don't forget to --enable-unicode
3. Don't forget grab your wxWidgets and not the system one
4. Or maybe wait for haskell-platform-2010.x to arrive in MacPorts

1. no more macports wxwidgets
=============================
you may see this error message (see Conor McBride's suffering on
http://www.haskell.org/pipermail/haskell-cafe/2009-December/071117.html ).

Undefined symbols:
 "_iconv_close", referenced from:
     _hs_iconv_close in libHSbase-4.2.0.0.a(iconv.o)
 "_iconv", referenced from:
     _hs_iconv in libHSbase-4.2.0.0.a(iconv.o)
 "_iconv_open", referenced from:
     _hs_iconv_open in libHSbase-4.2.0.0.a(iconv.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status

As I vaguely understand the issue, the problem is that
 (a) new libHSbase gets built using iconv.h and the like from -I/usr/include,
     but
 (b) having *any* package that introduces a -L/opt/local/lib in there (eg. a
     MacPorts-friendly Haskeline) 
and that some sort of difference between the two versions of iconv make (a) and
(b) an unhappy combination.

Having your wxHaskell be linked against your MacPorts wxWidgets causes similar
trouble if you have MacPorts iconv as well.

I didn't want to think about this any harder, so I just took MacPorts out of
the equation altogether by building my own wxWidgets 2.8.10 from source
http://www.wxwidgets.org/downloads/#latest_stable (Hooray for stow)

2. Don't forget to --enable-unicode when configuring wxWidgets
==============================================================
After untarring the wxWidgets source, I did this, the main point being the
Unicode stuff; the stow related business being extra details to make life
easier:

  port install stow
  ./configure --prefix=/usr/local/stow/wxMac-2.8.10 --enable-unicode
  make && sudo make install
  cd /usr/local/stow
  sudo stow wxMac-2.8.10

If you forget to enable Unicode, everything will build fine, but you'll get
widgets with only one letter on them.

3. Don't forget to build wxHaskell against YOUR wxWidgets
=========================================================
I did this:

  PATH=/usr/local/bin:$PATH cabal install wx

If you do not temporarily re-order the path, the Setup.lhs file in wxcore
will pick up the system wxWidgets which does not have the wxThread symbols
wxHaskell wants (so says the wiki for OS X 10.4), and when you launch your
application you'll be greeted by lots of annoying dialogue boxes that you
have to chase away.  Other things may break.

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

I wish there was some way we could just use the system wxWidgets with maybe
some sort of way of filling in the missing bits :-(

4. Maybe just wait for MacPorts haskell-platform to catch up
============================================================
Perhaps that would be the path of least resistance.

Interesting.  When I try that, the program compiles.  When I try to run it however, the window pops up, but the button does not accept a click.  

I thought to just get the macosx-app script from the source distribution.  In there, I find something called macosx-app-template.  I don't know how to generate the former from the latter.

[wxhaskell-users] Installing wx with cabal using Haskell Platform on Mac OSX.

[David P. <d...@vi...>]

Hi:

I have just installed the Haskell Platform 2009.2.0.2 on Mac OSX 10.6.2.  When I try to install wx I get the following error which I do not understand.
Can anyone give me a hint?

$ cabal install wx
Resolving dependencies...
cabal: cannot configure containers-0.3.0.0. It requires base >=4.2 && <6
For the dependency on base >=4.2 && <6 there are these packages: base-4.2.0.0.
However none of them are available.

[wxhaskell-users] Initial release of XrcAccessor

[Mads L. <mad...@ya...>]

Hi All

This is an initial release of XrcAccessor, which is a program to
generate type-safe accessor functions from XRC files. See attached
tar.gz.

As of yet, there is little documentation, but I do not think much
documentation is needed either. There are two examples that shows what
this small program can do in testsuite/TestControls.hs and
testsuite/TestMenu.hs. To run these two examples and the unit tests do:

> cd testsuite
> chmod 755 doTest
> ./doTest

If you are on MS Windows, you may need to alter the doTest script a bit.

You can install the program by:

runhaskell Setup.hs --user configure
runhaskell Setup.hs build
runhaskell Setup.hs install


Greetings,
