[Wxlua-users] wxLua build on mingw/msys

[Doug C. <dou...@gm...>]

Here are some things I did to build wxLua_Snapshot_2006-08-04.tar.gz
on Windows XP using mingw/msys. I don't pretend that these are the
"right" fixes for wxLua sources. Many are to generated files rather
than source files -- done out of ignorance of the full build process.
Others may interfere with successful builds with other tools or on
different targets. I am reporting them to help those attempting to
build with mingw/msys; maybe the authors/maintainers will find them
useful as well.

I started with an installed wxWidgets 2.6.3 and wxstedit 1.2.1. I
extracted wxLua_Snapshot_2006-08-04.tar.gz and did a
$ ../configure --disable-debug --enable-shared --enable-unicode --enable-wxluaedit-app

configure was unable to find wxstedit; apparently the method the
configure script uses to find wxstedit is not meant for Windows, it
seems to mess up with WXDLLEXPORT. Ignoring that, I did a make. It
proceeds for a while and then fails to compile wx_bind.cpp (this has
been reported earlier on this list as a bug in mingw's gcc 3.4.x).

1. hack wx_bind.cpp after make chokes on it inserting these lines:

#ifdef __MINGW32__
const wxPoint wxDefaultPositionHack = wxDefaultPosition;
const wxSize wxDefaultSizeHack = wxDefaultSize;
#define wxDefaultPosition wxDefaultPositionHack
#define wxDefaultSize wxDefaultSizeHack
#endif

before:

WXLUAOBJECT* wxLuaGetObjectList_wx(size_t &count)

2. in modules/wxluadebug/src/splttree.cpp add:

#ifdef __MINGW32__
#undef UNREFERENCED_PARAMETER
#endif

after includes and before:

static wxTreeItemId defaultTreeItemId;

3. in {my-build}/modules/Makefile add -lws2_32 to WX_LIBS

4. in {my-build}/apps/Makefile change:

WX_RESCOMP =

to:

WX_RESCOMP = windres --include-dir /usr/local/include/wx-2.6

5. in apps/wxlua/src/wxlua.rc  remove "..\\" from icon

6. in {my-build}/apps/Makefile add -lws2_32 to WX_LIBS

7. in apps/wxluacan/src/cansim.rc  remove "..\\" from icon

8. in apps/wxluafreeze/src/wxluafreeze.rc  remove "..\\" from icon

Latest release - 2.6.2.0

I tried out a snapshot and yes, there was a significant improvement.
I've decided to stick with the C++ anyway though - this project is
entirely a learning experience so thought it was worth improving my
C++ as well as my lua ;-)

I've now got it working to a reasonable level... have a look If you like:
http://www.mcs.vuw.ac.nz/~simesrich/luacalc-latest.tar.gz
supports excel-like functions & sorting.

You need to add these lines to your rules file probably. Just use the
dummy macros i you don't want to export them.

[Wxlua-users] (int) should be int

[klaas.holwerda <kla...@nl...>]

Hi,

 From my bindings.i file i get generated things like:

extern (int) a2dDrawer2D_methodCount;

and

extern (int) s_wxluatag_a2dLauWrapper;

On fedora gcc 4.0.0-8 this does not compile, if i remove the () and make 
plain int all is oke.

Why is it (int), maybe it is better to generate it as only int?

Re: [Wxlua-users] Multiple wxLuaState share global howto?

[Steve K. <ha...@ya...>]

Hi everyone,

I am thinking a solution but not yet implemented to
test it. I use wxApp to hold the data. So in MyApp
class I add two methods:

void SetGlobalObj(wxLuaState* );
void GetGlobalObj(wxLuaState* );

In SetGlobal I will get the lua table or light user
data (it could be a table / or lightuserdata from a
lua state.) Then set a member of MyAPP (which could be
an r array or pointer) to hold the references. In
GetGlobalObj I will push these pointer into a global
lua table so in lua code (another lua state) I will
get the references. After that I will dynamiccast to
the wx class type and use it.

So in second lua state call wxGetApp() and cast it to
MyApp() then call GetGlobalObj(**)

The purpose for now in my app is to use an already
contructed wxSocket and pass it to the new thread that
use different lua state. But if the above is correct
then I can see some other usage as well.

Any comment on it or I am just crazy :-)

Cheers,

There have been some fixes to the garbage collection in wxLua since
the last release. I don't see this using the snapshots. Hopefully
we'll have a new release in the next few weeks, the summer has been
very busy for me. :)

Good luck, you can also use the wxLuaState in C++ and the binding
generation code if you want to mix C++ and Lua a little more easily.
If you're not alreasy using a snapshot, try to compile it and
hopefully the mem leak you see is fixed.

Re: [Wxlua-users] wxLua with wxSocket ReadMsg() problem and work around.

[John L. <jla...@gm...>]

Thanks! You're perfectly right about using LastCount(), in fact the
wxWidgets docs even suggest that for the ReadMsg() function.

[Wxlua-users] wxLua with wxSocket ReadMsg() problem and work around.

[Steve K. <ha...@ya...>]

Hi everyone,

I have problem when using wxSocket in wxLua, ReadMsg
return some garbage at the end of the string. The
senario is:

c. WriteMsg(luastr, luastr:len())
s. ReadMsg(80)  // 80 is assured to be much bigger
than luastr:len() 

If using in C++ (wxWidgets) the buffer returned by
ReadMsg (even the nbytes is much bigger than the len
actually written to socket) is the correct len. Have
looked at the wxWidget source code and verify this.
However if using it in Lua, I get garbage string at
the end.

So I propose to change this line:

lua_pushlstring(L, (const char *)buffer, nbytes);

to 

lua_pushlstring(L, (const char *)buffer,
self->LastCount()); // skieu

in 
wxLua_wxSocketBase_Read(lua_State *L) and
wxLua_wxSocketBase_ReadMsg(lua_State *L)

I am not sure of the side effect of that change but it
worked for me, I never get any garbage since then :-)

Any comment?

Cheers

Re: [Wxlua-users] wxGrid cell renderer

[Richard S. <ric...@gm...>]

Thanks for the tips,

I think I'll be going with wxWidgets in C++, rather than wxLua as wxLua
seems to have a few memory leaks...
is this just my setup?
eg, the editor.wx.lua runs fine at first, but if I leave it open for more
than 15 minutes it becomes unusable with ~100mb ram and ~ 85% processor.
I'm running ubuntu 5 on an amd athlon xp


Although, My C++ isn't brilliant so I'll no doubt introduce some myself.

With the help of wxGlade I was able to get a basic grid interface working,
with a custom wxGridTableBase that will soon contain some basic bindings to
my lua code.

Wonderfully easy - I have the lua api working well.

Lua should make scripting arbitrary functions fairly easy.

This is probably best done using a lua table in addition to the
wxGrid's "cell value" which is just the displayed string value. The
lua table could store the values using a string represenation of the
coords, eg. string.format("%d, %d", row, col).

SetDefaultRenderer has been broken in wxWidgets for years, I submitted
a patch quite some time ago, but I think it's been lost since.

You can catch the events for set cell value and put them into a
separate lua table and then write to the wxGrid what the output of the
function or whatever was entered should be. I think this would be
simplest and should be enough.

The wxGrid component is hard to get a handle on at first glance, but
hopefully since you don't have to compile as in C++ you can get
something going fairly quickly.

[Wxlua-users] wxGrid cell renderer

[Richard S. <ric...@gm...>]

Hi List,
I'm completely new to wxLua so forgive me if I'm in going completely in the
wrong direction.

I have just started writing a spreadsheet program in lua that supports
functions, cell ranges and sorting. have got to the point where it really
needs a user interface to be useable to anyone so am investigating wxLua.

How can I use a wxGrid in such a way that the value typed into a cell is not
the same as the value displayed? (if a function is inputted)

I imagine i need to call grid:SetDefaultRenderer()
can a cell renderer object be defined from lua? As it's user-data, I suspect
this might not be possible?

Help would be appreciated, though I suppose I should read up on wxWidgets a
bit more before I launch into this myself...

I don't think this is possible. How would you keep the two states
updated with the each other's global vars? You could try to push your
own C function and catch the __newindex (IIRC) and the other metatable
functions for the global table _G and explicitly copy the values
between the two states.

Good luck,

These errors make no sense? WXLUACLASS is a struct without any
wxClassInfo at all! You get the wxClassInfo typically from a
DECLARE_[ABSTRACT/DYNAMIC]_CLASS in a class declaration.

What are the line numbers and a little bit of the code? What version
of wxLua are you using, one of the snapshots?

Maybe you're defining WXDLLIMPEXP_WXLUA to something strange?

You should definitely try to compile the samples using the build files
in the build dirs as a start. I use the MSVC 2005, the free GUI
compiler without any problems building using the non-dll DEBUG or
RELEASE settings.

[Wxlua-users] Help with a compiling problem

[Chris C. <wan...@ho...>]

Hi all,

I'm very new to using wxlua and I was wondering if there are any good 
tutorials around on the wbe that show how to setup wxlua in c++ as my 
searches have ended up with me running around in circles.

But to the problem I've created a gui using the luaeditor app but now I 
would like to make it a standalone .exe and I've run into a problem while 
compiling.  If I use #include "wxlua/include/wxlua.h" or #include 
"wxlua/include/wxlstate.h" I get a lot of compile errors in the wxlbind.h 
along the lines of.

error C2143: syntax error : missing ';' before '*'
error C2501: 'WXLUACLASS::wxClassInfo' : missing storage-class or type 
specifiers

Am I missing some other include files that I need to include?  I have looked 
at the c++ apps that came with wxlua (although I havent tried compiling any 
of them) and it doesnt seem they are doing anything different when including 
either of those files.

Currently I'm using visual studio .net 2003 as a compiler and wxlua 2.6.3.  
Any help would be greatly appreciated.

The uncommented line is written exactly as the C++ function is to make
it easy to check that the parameters are the same when the files are
updated to a newer version of wxWidgets. I've tried to document all
the %override functions in the .i files appropriately.

Ok then we'll keep it this way. There are only a few of these so it's
not a big deal to maintain them.

I think it's ok. This is one of the overridden functions where the

the array as a lua table.

// %override [unsigned int, lua string table] wxDir::GetAllFiles(const

My apology, it is just that I read the un commented line 

%wxchkver23 static unsigned int GetAllFiles(const wxString& dirname, wxArrayString *files, const wxString& filespec = "", int flags = wxDIR_DEFAULT)

and still  think that the method is still using *files  its argument so I still pass dummy args into it and it failled, then whining about it :-). I should look at the override line .

I have been wondering if it might be simpler to use wxArrayString for
these cases rather than returning a lua table of strings. You can
always use the added function wxArrayString:ToLuaTable() to get it as
a table if you like.

What do you think? On one hand it's nice to use the native lua table
for arrays like this, but on the other hand the bindings are easier
with fewer overrides and confusion with the wxWidgets docs if we keep
it as a wxArrayString.
I personally prefer lua table; as I can get it out, process it using lua code etc. It is just much easier to use lua then , my memory is not good, and lots of time I have to open wx docs to find a method name etc.. but I can not forget :
for i,v in pairs(bla) do    :-)  end

Re: [Wxlua-users] wxString, Unicode problem .... (Fixed,)

[Steve K. <ha...@ya...>]

Hi John,

The sample is very simple. You create any frame with a text widgets on it, Enable wxTE_RICH and wxTE_RICH2 as well.  Add some code to display the getvalue of the text widget and display it using wx.wxMessageBox for example. You will get null (nothing displayed)

The unicode sample you can get from this site  http://vnexpress.net/    just copy some text there and paste.

--  Sample code
f=wx.wxFrame(wx.wxNull, -1, "")
s0=wx.wxBoxSizer(wx.wxVERTICAL)
f:SetSizer(s0)
idtext=wx.wxID_HIGHEST+1
text=wx.wxTextCtrl(f, idtext,  "",  wx.wxDefaultPosition, wx.wxDefaultSize, wx.wxTE_MULTILINE+wx.wxTE_RICH+wx.wxTE_RICH2)
b0=wx.wxButton(f, 10000, "Display")
s0:AddWindow(text)
s0:AddWindow(b0)
f:Connect(-1, wx.wxEVT_COMMAND_BUTTON_CLICKED, function (e) 
wx.wxMessageBox(text:GetValue() )
end)
f:Show(true)
-- end sample code

The problem only happened in win32 (all window version). Linux GTK is fine which make me think it is a bug in the wxWidget conversion code in win32. Actually I did not find errors in the old code, but in wxWidgets we just have too many ways of doing such conversions and the old wxLua code is not the same as the code I usually using in my apps which proves to work fine (I have had lots of strange problem in these conversion things until I found a reliable way of doing such conversion) So I replace it with my code and it works as expected. 


John Labenski <jlabenski@g
Where did you get the Unicode string that doesn't work in your sample
program? Could you post one? I tried different things in wxGTK
compiled in Unicode, but I had no problem with the original conversion

Yeah as I said, only happen in win32.

Do we also need to care about embedded NULLS? There is a lua function
to get the string as well as it's length, maybe we should use that
too? Perhaps the unicode string had embedded NULLs?
The sample in the website I said before is Vietnamese text ; coding using standard UTF-8, not quite sure if it contain NULL but I guess not. 
> #if wxUSE_UNICODE
>   return wxString(luastr, wxConvUTF8);
The above part is tested as I use the unicode built of wxWidgets
> #else
>   return wxString(wxConvUTF8.cMB2WC(luastr), *wxConvCurrent);
Always wxConvUTF8 in Unicode? Not wxConvCurrent?
Have not tested in non Unicode built of wxWidgets. but in this case I gues it will use  wxMBConv.cMB2WC  or wxConvLibc.cMB2WC. So this part should change accordingly (it may even work without changes but let me test in non unicode built first)

I don't understand why in non unicode you convert it to a WC array and
then back. You should be able to just to "return wxString(luastr)"
since everything is ASCII.
Even wxWidgets is built without unicode support but the string we get it  might contain unicode chars so it is not pure ASCII.

I think it's ok. This is one of the overridden functions where the
function call doesn't take the input wxArrayString, but rather returns
the array as a lua table.

// %override [unsigned int, lua string table] wxDir::GetAllFiles(const
wxString& dirname, const wxString& filespec = "", int flags =
wxDIR_DEFAULT)

I have been wondering if it might be simpler to use wxArrayString for
these cases rather than returning a lua table of strings. You can

Where did you get the Unicode string that doesn't work in your sample
program? Could you post one? I tried different things in wxGTK
compiled in Unicode, but I had no problem with the original conversion
code. I am not expereienced with Unicode so the original code was from
some posts on wx-users and the STC contrib about how to convert back
and forth.

Do we also need to care about embedded NULLS? There is a lua function
to get the string as well as it's length, maybe we should use that
too? Perhaps the unicode string had embedded NULLs?

Always wxConvUTF8 in Unicode? Not wxConvCurrent?

I don't understand why in non unicode you convert it to a WC array and
then back. You should be able to just to "return wxString(luastr)"
since everything is ASCII.

Originally:
wxConvertWX2MB == wxConvCurrent->cWX2MB(wchar_t* s)
cWX2MB returns wxUSE_UNICODE ? cWC2MB(wchar_t* psz) : psz

So again, always use wxConvUTF8?

I will try it in MSW in non unicode tomorrow and GTK w/ unicode tonight.

[Wxlua-users] Bug: Wrong parameters in wxDir:GetAllFiles()

[Steve K. <ha...@ya...>]

Hi,

I found a bug in method GetAllFiles(). The overwrite function pass the wrong parameters positions.

static int LUACALL wxLua_wxDir_GetAllFiles(lua_State *L)
{
    wxLuaState wxlState(L);
    unsigned int returns;
    // get number of arguments
    int argCount = lua_gettop(L);
    // int flags = wxDIR_DEFAULT

// Wrong code follow. SHould be 5  not 4 as the first param is luastate

//    int flags = (argCount >= 4 ? (int)wxlState.GetNumberType(4) : wxDIR_DEFAULT);  

int flags = (argCount >= 5 ? (int)wxlState.GetNumberType(5) : wxDIR_DEFAULT);

    // const wxString& filespec = ""

// 3 is wrong, should be 4

wxString filespec = (argCount >= 4 ? lua2wx(wxlState.GetStringType(4)) : wxString(wxT("")));
    // wxArrayString *files
    wxArrayString files;
    // const wxString& dirname
    wxString dirname = lua2wx(wxlState.GetStringType(2));
    // call GetAllFiles
    returns = wxDir::GetAllFiles(dirname, &files, filespec, flags);
    // push the result number
    lua_pushnumber(L, returns);
    wxlState.PushwxArrayStringTable(files);
    // return the number of parameters
    return 2;
}
