I tried compiling the exec-examples and it works like a charm :/
Is anyone else experiencing the same problem?

I've "visualized" the problem at

[wxhaskell-users] Is there "Region" in wxHaskell?

[<hai...@ya...>]

Hi,

Do you know if there is a "Region" definition in wxHaskell?

In graphics libraries of both Windows and X-Windows, we can use Regions
and related computations (Union, Intersec ...).  I am trying to
implement graphic regions in Haskell but the performance is a critical
problem. It would be great if wxHaskell supports this.

Thank you,

Haitao 

[wxhaskell-users] Freeze and thaw.

[Lemmih <le...@gm...>]

Greetings,

I've been trying to use windowFreeze and windowThaw to reduce
flickering when updating a notebook.
However, even when omitting 'windowThaw' after updating, it had
absolutely no visual effect. What's the correct use of
window{Freeze/Thaw}?

Re: [wxhaskell-users] Trouble building wxhaskell-0.9 samples

[Jinwoo L. <jin...@gm...>]

Hi,

I applied the patch files that Georg Martius posted before, and 
succeeded to build and install wxhaskell 0.9 using GHC 6.4.
But when I try to compile using wx package or load wx package using 
GHCi, it fails to load wx package.

The screen of loading GHCi is like following.

Re: [wxhaskell-users] Trouble building wxhaskell-0.9 samples

[Patrick S. <mai...@st...>]

Hi,

Hmm It looks like that the package isn't installed correctly.
It would be nice to see what the command

ghc-pkg list

brings on your machine. Did you install the package locally in your "home dir" 
on windows or global? This line
> Using package config file: C:\Documents and Settings\Jeff
> Lasslett\Application Data\ghc/i386-mingw32-6.4/package.conf
seems a bit confusing to me because there is a change from backslash (window 
separator style) to a normal slash. Could this be a kind of bug?

Anyway, when the compilation of wxhaskell is done and you do a make install 
then you should see that all the stuff is copied to a directory and after 
that the package file of the ghc is updated succesfull. If everyting is 
correct you should be able to make something like:

mai99dnn@patrick:/data/software> ghci -package wx

[wxhaskell-users] Trouble building wxhaskell-0.9 samples

[jeff l. <m4d...@gm...>]

Greetings,

Firstly, my thanks to Patrick Scheibe for advising me of the diffs I
needed to get wxhaskell-0.9 to compile and install.  (See thread
"Trouble creating wxhaskell 0.9").

I am now stuck trying to compile the HelloWorld.hs sample program.
Here's a transcript of my attempt:

Re: [wxhaskell-users] Trouble creating wxhaskell 0.9

[Patrick S. <mai...@st...>]

Moin.

You should have a look at the previous discussions of Georg, Daan and me..
The problem is the changed behavior of the new ghc-6.4.
Try to patch the makefile, makefile.lib and configure with the patches from 
Georg.

http://sourceforge.net/mailarchive/forum.php?thread_id=6815257&forum_id=34197

You got this mail, do you?
If not I can put the patches on my site.

Cheers
Patrick

Re: [wxhaskell-users] processExecAsyncTimed dies with

[Patrick S. <mai...@st...>]

Hi again.

I think it isn't that easy.
wxhaskell gives the command to the wxWindows execution function(s).
You can first try to make the following:

go to your sourcecode of the wxWidgets and try to compile and test the exec 
sample. This is quite the same like in haskell. Have a look if you can make 
commands without crashes.. 

/data/software/haskell/wxGTK-2.4.2/samples/exec

Re: [wxhaskell-users] processExecAsyncTimed dies with

[Patrick S. <mai...@st...>]

Hi,

The sample is running very well on my machine. I don't think that is wxHaskell 
problem. Maybe it is a good way to figure out which commands are called 
processExecAsyncTimed.
Maybe it calls just a normal haskell IO function which crashes on yours.

I have a linux box, version 6.4.20050215 (but that worked on my ghc-6.2.2 too) 
and wxHaskell version 0.9 (but in the 0.8 lib the sample runs as well).

Cheers
Patrick

[wxhaskell-users] processExecAsyncTimed dies with

[Tobias E. <tu...@dt...>]

Hello everyone!

I have got some problems with the process example
http://cvs.sourceforge.net/viewcvs.py/wxhaskell/wxhaskell/samples/wx/Proc=
ess.hs?rev=3D1.13&view=3Dauto

When I try to run a command, it dies with the error:
Fail: Prelude.chr bad argument

This happens when the process terminates (the OnRecieve-stuff seems
to work fine)
I've tried this with the wxhaskell-cvs, on two different machines

Has anyone else experienced this?

Cheers,
Tobias Engvall

Thanks a lot!

I'll try your patches. My current workaround is/was to disable 
dependency generation, but this is of course not a sustainable 
solution. BTW, I also had to write package description files in the new 
format. Which ones do you use?

Some of the examples under directory 'contrib' are broken in version 
0.9. I needed to make a number of (superficial) changes to get them to 
compile and run. Interestingly, and this is something I often observed 
with Haskell, as soon as I got it to compile, everything worked as 
expected. The changes where easy to make, using the haddock generated 
docs. WxHaskell is cool!

set treeCtrl [style := wxTR_EDIT_LABELS] helps! :)

[wxhaskell-users] Yet another treeCtrl question

[David W. <da...@dt...>]

Hi again! 

How do I edit an item label in a treeCtrl? I suspected treeCtrlEditLabel
should fire a TreeBeginLabelEdit event or something, but it seems 
to do nothing.

[wxhaskell-users] treeCtrl Ptr arguments

[David W. <da...@dt...>]

Hi!

the Documentation for the treeCtrlGetFirstChild says: 

treeCtrlGetFirstChild :: TreeCtrl a -> TreeItem -> Ptr CInt -> IO TreeItem   
usage: (treeCtrlGetFirstChild obj item cookie).

what's up with the Ptr Cint? How do I construct one and what should it 
point to?

Hi David,

I think there is in wxWidgets: EVT_TEXT but I can't find its 
counterpart in wxHaskell.

Your solution with the keyboard event may work if you do it like this:
   on keyboard = do { propagateEvent; ...Do what you want to do ... }
This might process the keystroke before you look at the new contents of 
the text entry field.

Your second question about tree controls I can't answer.

Most resources are managed, i.e. handled by the Haskell garbage 
collector. If you allocate things by using WXCore functions they might 
not be released at the end of the program. You can use objectDelete (I 
believe) to release an object yourself. I never got rid of all the 
leaks but if I look at the number of bytes that are leaked it's okay.

Cheers, Arjan

[wxhaskell-users] Misc questions

[David W. <da...@dt...>]

Hi!

I have a couple of questions about wxHaskell.

First, is there an event that I can respond to that fires when the 
text has been changed in a text control? Right now i'm listening to
the "keyboard" event. This is unsatisfactory because the "text" property
of the textcontrol isn't updated until _after_ the event has been handled.
(I'm trying to update the text of a label when a user inputs text in a 
text control, in "realtime")

Second, is there a way to change the behaviour of the treecontrol so that
it displays "selectedImage" for a certain node as long as the node is 
expanded? This is the desired behaviour for a tree that displays both
files and folders (ie. one that doesn't have a file view aswell).

Finally, the wxWidgets debug library (compiled with vc++) reports about 
memory leaks when I exit my wxHaskell program. Since I don't manually  
handle any resources, is this maybe the result of bugs in wxHaskell?

You can also set the LD_LIBRARY_PATH variable to contain the path where t=
he library lies.

[wxhaskell-users] wxhaskell 0.9 added to Fedora Haskell

[Jens P. <je...@ju...>]

FYI I rpm-packaged wxhaskell-0.9 and added it
to the Fedora Haskell package repository[1].

Ok, the solution to this is just to configure with --with-opengl.

I worked round this by moving the library to system libdir.
