You can use XRC files with wxHaskell, although I should note that they
are not currently type-safe (so you will get a crash if you load a
resource and treat it as the wrong type of object (e.g. load a button
into a list box).

Someone (Mads, I think) showed a proof of concept for type safety on
XRC, but I haven't had the time to implement it fully so far.

I use something called wxFormBuilder on Windows to create my XRC
files, which seems a little more complete than wxGlade, although both
will do the job.

There's a sample provided with wxHaskell which shows how to use XRC
files, should you decide to go this way.

I've never tried - I use Visual Studio to build wxWidgets and wxC -
but it should work, as more users seem to use FOSS build chains than
Microsoft, and all of the Unix platforms use exclusively FOSS tools to
build. The wxWidgets build system is very configurable, and most build
options seem to exist on all supported platforms. In general, I've
found that if wxWidgets team claim something works, it works well
(i.e. they do their QA!)

There are people who use mingw to build the wxC component of wxHaskell.

The single DLL aspect may require some minor fiddling with the wxC
makefiles, but I suspect it should work once you've found the correct
set of options.

In principle, once it is in wxWidgets, it's pretty easy (trivial for a
reasonably experienced C++ programmer) to wrap any new components -
that's to say, once you have built wxWebKit, making it accessible from
wxHaskell is easy (if tedious - for large/complex APIs).

Yes, that was me. See
http://article.gmane.org/gmane.comp.lang.haskell.wxhaskell.devel/364/match=xrc

I do not think it would take a long time, to make this usable for 90-95%
of the widgets in a XRC file.

However, personally I have no desire to use Glade or XRC files. But I
know others do - to each his own.

I do not want to develop this any further, for an imaginary user who may
or may not exists. However, if somebody wants to this further developed
and is willing to be ginnypig I could do so. But it is only second best.
The best would be for somebody with a GUI app using XRC file, to
implement type-safe XRC accessors themselves.

Greetings,

Mads

Personally I have no opinion on Glade as I've never used it. When I say 
I like the idea of specifying a GUI with XML, the picture in my mind is 
something like XUL or HTML (hey, I'm a web developer). But these are 
much simpler than Glade XML. AFAIK you are not supposed to write Glade 
XML by hand.

Daniel.

I do not know why the moderation flag was set for you. Maybe Mailman do
it automatically somehow. I have removed it now.

Re: Moderation

Hi Mads,

it's set so for me too.

You sure it's not set like that for everyone?

Re: Moderation

Hi all,

Regrettably, we had to turn on moderation for all new subscribers about
a year ago after list spamming started to happen frequently.

Our policy is that as soon as it is clear that a mail is coming from
someone with an issue appropriate to this list, we turn off moderation.
I put my hands up and apologize for forgetting to do this in your case,
Daniel.

Regards
Jeremy

3 Layout quiz

Hi MailList wxHaskell user:

    I am new to wxhaskell.
    In reading examples and writing my test program, I need some help about Layout controls.

    Reading wxhaskell/samples/wx/Layout.hs, here is the code piece.

>  set f [defaultButton := ok
>        ,layout := container p $
>                   margin 10 $
>                   column 5 [boxed "coordinates" (grid 5 5 [[label "x:", hfill $ widget xinput]
>                                                           ,[label "y:", hfill $ widget yinput]])
>                            ,floatBottomRight $ row 5 [widget ok,widget can]]
>        ]

    I donot know why there must be an container p out of the layout of the controls. I
have tried remove the container, after that, the text boxes and buttons dispeared. Why ?

    In my test, I have written a piece of code like this.

>  set f [layout := column 2 [hfill $ row 1 [hfill $ label "Left"
>                                           ,vfill $ vrule 2
>                                           ,hfill $ label "Right"]
>                            ,hfill $ hrule 1
>                            ,floatCenter . margin 1 . grid 5 5 $
>                               map (\i -> map (label . show) [i..(i+5)]) [1..5]
>                            ]
>        ...

    In the above code, the frame f has a status bar. I have two questions about it.
