[Wxlua-users] still bindings problems

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

Hi John,

Your idea to add precompiled headers like this does not work. Also 
othere changed you said you made, made no difference.

hook_cpp_binding_header_includes = "#include 
\"general/include/a2dprec.h\"\n..#include \"wxbind/include/wxbind.h\"\n"

I think the only thing that will be correct is to place the next at as 
the first include file in *.cpp generated.
This is what the comment says, and how it worked before.

-------------------------------------------------------------------------------
-- Set any #includes or other C++ code to be placed verbatim at the top of
--   every generated cpp file or "" for none
hook_cpp_binding_includes = "#include \"general/include/a2dprec.h\"\n"

With this setting i get in my lubind.cpp:

#ifdef __BORLANDC__
    #pragma hdrstop
#endif

#ifndef WX_PRECOMP
     #include "wx/wx.h"
#endif

#include "wxlua/include/wxlstate.h"
#include "luawraps/include/luabind.h"
#include "general/include/a2dprec.h"

But i need this, to make it work.

#ifdef __BORLANDC__
    #pragma hdrstop
#endif

#ifndef WX_PRECOMP
     #include "wx/wx.h"
#endif

#include "general/include/a2dprec.h"
#include "wxlua/include/wxlstate.h"
#include "luawraps/include/luabind.h"



If i change in genwxbind.lua in the next function:

function GenerateHookCppFileHeader(fileData)

to this again, all is oke as before, what that be wrong in other situations?
If so we better have and extra variable to contain a precompiled header 
include in the rules file.



function GenerateHookCppFileHeader(fileData)
    table.insert(fileData, "// 
----------------------------------------------------------------------------\n")
    table.insert(fileData, "// This file was generated by genwxbind.lua \n")
    table.insert(fileData, "//\n")
    table.insert(fileData, "// Any changes made to this file may be lost 
when file is regenerated.\n")
    table.insert(fileData, "// 
----------------------------------------------------------------------------\n")
    table.insert(fileData, "\n")
    table.insert(fileData, "#ifdef __BORLANDC__\n")
    table.insert(fileData, "    #pragma hdrstop\n")
    table.insert(fileData, "#endif\n")
    table.insert(fileData, "\n")
    table.insert(fileData, "#ifndef WX_PRECOMP\n")
    table.insert(fileData, "     #include \"wx/wx.h\"\n")
    table.insert(fileData, "#endif\n")
    table.insert(fileData, hook_cpp_binding_includes or "")
    table.insert(fileData, "\n")
    table.insert(fileData, "\n")
    table.insert(fileData, "#include \"wxlua/include/wxlstate.h\"\n\n")
    table.insert(fileData, "\n")

    if includeList then
        for idx = 1, table.getn(includeList) do
            table.insert(fileData, "#include \""..includeList[idx].."\"\n")
        end
    end
    table.insert(fileData, "#include \""..hook_cpp_header_filename.."\"\n")
    table.insert(fileData, "\n")
    table.insert(fileData, "\n\n")

    return fileData
end

[Wxlua-users] lua.exe OR lua5.1.exe

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

Hi,

At home i use Vc2003.net and here VC6.
It seems that VC6 produces wxlua-lua.exe and lua5.1.exe in the wxLua/bin.
But i am sure i did not see this at home, there i get lua.exe, and not 
wxlua-lua.exe nor lua5.1.exe.

I can only explain this because of using VC6 or Vc2003.net.

Because of this on Vc6   wxLua/wxluacan/src/genwxbind.bat will not work.
And this is the same for my own binding, where is assume lua.exe is  
available from wxLua.

If i go to the target app_lua in wxLua.dsw, i see that it produces this 
as executable.
 
C:\data\art2d\wxluacvs\wxLua\bin\wxlua-lua.exe

And lua5.1.exe comes from target app_verbatimlua.

I will check again at home why i do get lua.exe there. The thing is that 
VC2003 uses the same project files, only translates them. So this would 
be a strange thing to happen.
Maybe it is a matter of a clean check out.

In any case, what should the real naming be?
I would prefer the same name on unix and windows.
Once that is clear we should update the binding generation scripts to 
use it.
Although it looks like wxLua/bindings/genwxbind.bat is already using 
wxlua-lua.exe, but on genwxbind.sh it is lua via the path.
Why not wxlua-lua.exe also on Unix?

Thanks for some clarification,

Klaas

[Wxlua-users] multi-level C++ namespaces

[Darwin S. <dar...@ho...>]

Hello,

I have been having problems with generating the bindings for classes when 
they exist in sub-namespaces of the main namespaces e.g.
a::b::MyClass

I was not able to set this namesace in the rules file using the 
hook_cpp_namespace because this caused problems with the #ifndef at the top 
of the generated binding header e.g.:

<code>
#ifndef __HOOK_WXLUA_a::b_H__
#define __HOOK_WXLUA_a::b_H__
</code>

It also seems to only process the first part of the namespace:
'wxluatest.h:58: error: ‘wxObject_a’ has not been declared'

I was just wondering if this is supported or if there is any way around this 
short of editing the generated binding files?

Thanks in advance,
D. S.

I did it, and 'wxLuaState_newthread_handler()' *is* being called.

Here it is: http://www.stackedboxes.org/~lmb/Balaio/wxLuaIdleCoroutine.zip

Now, running this example I found some information that may help
finding what's going wrong. Here are some notes about this:

1. This example works with the wxLua version I was using before
starting to have problems (CVS 2006-04-14). (Just need to change
'Connect' to 'ConnectEvent', and make it look for the 'wxluasetup.h'
in the (im)proper place).

2. All other tests made with wxLua Snapshot 2006-06-03.

3. Running the example as is, I get the following output in the console:

wxLuaState_newthread_handler L 135088648 L1 135631296, L_wxlsdata
135086608 L1_wxlsdata 135567808
lua: Error while running chunk
app.lua:41: attempt to call method 'Connect' (a userdata value)
stack traceback:
        app.lua:41: in function 'new'
        app.lua:91: in function <app.lua:80>

(notice that 'wxLuaState_newthread_handler()' is called)

4. So, the error happens in the "main thread", not inside the
coroutine. This means that the problem is not where I thought it
was... (before this, in my application, I was getting the same error,
but it was happening (coincidentally?) from inside the coroutine
code).

5. I tried to comment out the code that creates the coroutine (and the
asserts I added to check if a coroutine is passed to the
'ProgressWindow') and run the program again, just to see where the
error would happen. The call to 'Connect' succeeded

Sorry... "send" looks so much like "save" :-)  I still have a final comment...

6. So, I guess that when the coroutine is created, something is done
that confuses further calls to wxLua. I haven't checked the wxLua
implementation, but from these tests, I think my conclusion makes some
sense.

That's it for now. Feel free to ask for further tests. As I said, I'll
be busy for some more time, but I can do something whenever I find
some space in my schedule ;-)

Thanks for all,

[Wxlua-users] wxLua win98 memory allocation error..

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

Hi,

I have repeatedly got the message when running the app in win98. With window 2000 and above, no problem. The app is like:

at  wxWidget app, at OnInit I start a wxLuaState and call run a file which is an command line argument.
I have a wxThread class in c++ which just very simple thread to spawn another wxLuaState and run a file.lua . This class is accessible in lua script.

Basically the first arg is the main window to open the GUI, and there is a menu to allow the thread to run another lua file in a different thread ; a server process. Everything works as expected in win2k . XP, but not win98.  Even I do not have thread at all; just use wxLua and run the server script, which is a non GUI apps it gives the memory allocation error as well. However if I use the lua50.exe interprepter it works just fine so at the moment I have to wrap it using os.execute()  call and use lua50.exe.

Is there any GUI conflict if we use wxLua to run a Non GUI script in win98?

Cheers,

Re: [Wxlua-users] how to use wxLuaHtmlWindow in XRC?

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

This is because the wxLuaHtmlWindow is a subclassed wxHtmlWindow.
A similar example, I got  my custom 
textCtrl : public wxTextCtrl 
(add drop down list val). I export it to wxLua use genwxbind. Then use XRC ; the class be wxTextCtrl  and subclass is sk_TextCtrl. It worked. (mean no error, can DynamicCast("sk_TextCtrl") in lua, 

I thought it should work with wxLuaHtml as well, I had a look at wxhtmlwin.cpp it is similar in my case. 

but somehow  XRC handler can not find it.

Anyway If I want to do that way probably I have to write custom XRC handler for wxLuaHtml . 

Cheers,

This is because the wxLuaHtmlWindow is a subclassed wxHtmlWindow.
Isn't there a way to have XRC create a window from the wxClassInfo's
name?

Sorry I've never used XRC resources myself.

See the wxWidgets technote 14, docs/tn0014.txt and search for
  <object name="MyList1" class="wxListCtrl" subclass="MyListCtrlClass">

This is kinda' hard to read. :/

Take the choices.wx.lua sample, add the line to the leave window.

 frame:SetStatusText("wxEvents from contols will be displayed here", 0)
 frame:Connect(wx.wxEVT_LEAVE_WINDOW, function(event) print("Hi") end)

It works for me. Remember that the frame is mostly hidden by the
notebook so you have to find a spot where it's exposed. Try it out for
the listbox as well.

Yes the EVT_LEAVE_WINDOW( test::OnLeaveWindow ) is similar to
wxEvtHandler::Connect. There are some differences however. The Connect
function uses a dynamic event table that is processed before (IIRC)
the static event table generated with the macro so you have to use
event:Skip() to get the default processing to work in some cases.

If i understand it well, it will not be at the top of "the file", or 
does that mean something else?.
 The precompiled header ( which is a2dprec.h ), has to be the very first 
in every cpp file that is generated, else VC6 gives problems in 
compiling with it.

I am a bit confused, by what is exactly what in the following two:
 
-------------------------------------------------------------------------------
-- Set any #includes or other C++ code to be placed verbatim at the top of
--   every generated cpp file or "" for none
hook_cpp_binding_includes = ""

-------------------------------------------------------------------------------
-- Add additional include information or C++ code for the binding header 
file.
--  This code will be place directly after any #includes at the top of 
the file
hook_cpp_binding_header_includes = ""

This evening i can try your modifications from CVS,

regards,

Klaas

Events like mouse and wxEVT_LEAVE_WINDOW need to be connected directly
to the window. The rule is that if the event is not derived from a
wxCommandEvent it won't travel up the event handler chain. You can
also tell by the event macro signature, for example
EVT_LEAVE_WINDOW(func) doesn't take an id.

Try:
button:Connect[Event](10001, wxEVT_LEAVE_WINDOW, function(event)
print("Bye.") end)
Or
button:Connect[Event](wx.wxID_ANY, wxEVT_LEAVE_WINDOW, function(event)
print("Bye.") end)

The latter may be required for some reason, that is a wxWidgets issue however.

I'll most likely be quite busy this week (and possibly the next week,

Try unremming the wxPrintf statement in wxLuaState_newthread_handler
in modules/wxlua/src/wxlstate.cpp and see if that gets run when the
coroutine is created. We had to make changes for running wxLua as a
lua module for require, maybe it's broken now.

    John Labenski

ps. could you send a little coroutine code to show the problem, we
could add it as a sample in wxLua to help verify that they still work.
I seem to have lost my little sample.

Re: [Wxlua-users] wxLuaHtmlWindow how to catch the event?

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

OOPS  My mistake it should prefixed with wx.

So most of them works but  not  wxEVT_LEAVE_WINDOW

      
frame=wx.wxFrame(wx.wxNull, 10001, "test")
--frame:ConnectEvent(10001, wx.wxEVT_ENTER_WINDOW, function (event) print"Enter work" end) 
frame:ConnectEvent(10001, wx.wxEVT_LEAVE_WINDOW, function (event) print"Leave not work" end) --not work
--frame:ConnectEvent(10001, wx.wxEVT_MOTION, function (event) print"Motion Work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_DCLICK, function (event) print"work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_DOWN, function (event) print"Left down work" end)
--frame:ConnectEvent(10001, wx.wxEVT_LEFT_UP ,function (event) print"Left up work" end)
--frame:ConnectEvent(10001, wx.wxEVT_RIGHT_DCLICK ,function (event) print"Right dclick work" end)
--frame:ConnectEvent(-1, wx.wxEVT_RIGHT_DOWN ,function (event) print"Right  work" end)
--frame:ConnectEvent(-1, wx.wxEVT_RIGHT_UP ,function (event) print"Right up  work" end)
frame:Center()
frame:Show(true)
For the HTMLWIndow I think the COMMAND EVENT works but not for mouse event which is natural for a button, thus I think it is ok

Sorry for a big noise. :-)

ANyway the wx.wxEVT_LEAVE_WINDOW not work which I do not understand yet..

Can you post a little bit of code to show how it should work and what
I should expect to see based on your C++ tests. I have never used the
HTML widget in lua or C++.

Another event strange was: Re: [Wxlua-users] wxLuaHtmlWindow how to catch the event?

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

Hi,

I have a minimum simple script to show as below:

frame=wx.wxFrame(wx.wxNull, 10001, "test")
--frame:ConnectEvent(10001, wx.wxEVT_ENTER_WINDOW, function (event) print"Enter work" end) 
--frame:ConnectEvent(10001, wx.wxEVT_LEAVE_WINDOW, function (event) print"Leave not work" end) --not work
--frame:ConnectEvent(10001, wx.wxEVT_MOTION, function (event) print"Motion Work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_DCLICK, function (event) print"Not work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_DOWN, function (event) print"Left down not work" end)
--frame:ConnectEvent(10001, wxEVT_LEFT_UP ,function (event) print"Left up not work" end)
--frame:ConnectEvent(10001, wxEVT_RIGHT_DCLICK ,function (event) print"Right dclick not work" end)
--frame:ConnectEvent(-1, wxEVT_RIGHT_DOWN ,function (event) print"Right down not work" end)
--frame:ConnectEvent(-1, wxEVT_RIGHT_UP ,function (event) print"Right up not work" end)
frame:Center()
frame:Show(true)

Pls note that the above script, the equivalent C++ work as expected. I have tested it using Dialogblocks; add one frame and add the event accordingly.


This one is not related to html window at all

And the HTML window; as you suspect from the above one;  it work with wxEVT_COMMAND_BUTTON_CLICKED  but not with  wxEVT_BUTTON_CLICK  or wxEVT_LEFT_DCLICK. I have not tested it with another kind of event.

      
frame = nil html  = nil htmlTextPage = [[<html>                    <head>                    <title>Not working</title>                    </head>                    <body>                         <h3>wxHtmlWidgetCell demonstration</h3>                         There are three bound widgets below.                         <hr>                         <center>                             <lua text="first widget"                                 x=100 y=70>                         </center>                     </body>                  </html>]] function main()     -- create the frame window     frame = wx.wxFrame( wx.wxNull,                         wx.wxID_ANY,                         "HtmlWindow Demo",                         wx.wxDefaultPosition,                         wx.wxSize(450, 450),                         wx.wxDEFAULT_FRAME_STYLE )     -- create a simple file menu  -- THIS WORKS                         --   frame:ConnectEvent(30000, wx.wxEVT_COMMAND_BUTTON_CLICKED,

A copy of my original email follows, I hope it is readable now. Sorry
for thee trouble.

----

Hello, it's me again...

I'm still struggling to use the latest wxLua snapshot. Currently my
problem is calling wxLua stuff from a Lua coroutine.  If try to call
any wxLua method from a coroutine I get an error. For example, if I
have something like

  local bmp = wx.wxEmptyBitmap (0, 0)
  bmp:LoadFile ("Foo.xpm", wx.wxBITMAP_TYPE_XPM)

I get the following message:

"Attempt to call method 'LoadFile' (a userdata value)"

It seems that wxLua *is* being compiled with WXLUA_LUA_NEWTHREAD
defined, and I have no idea on what else may be wrong.

I'm using wxLua CVS snapshot 2006-05-27, wxGTK 2.6.2, GCC 3.4.3 on Linux.

Thank you,

LMB

Have only one of these. You can also try
"hook_cpp_binding_header_includes" in the rules file.

Maybe, I think the problem has to do with writing the bindings out
sorted. This really has to be done since lua tables using string keys
come out arbitrarily and so CVS diffs are useless and in some cases it
seems as though everything gets shifted around even for some tiny
little change.

There is also the problem that XWindows very rudely #defines "Above"
and "Below" which we need to #undef *after* all the includes.

Let me know if "hook_cpp_binding_header_includes" works for you, it'll
put the #include in the .h binding file right at the top. Do a new
checkout, I've adjusted things a little.

    John Labenski

[Wxlua-users] Empty arguments problem.

[k. h. <kla...@nl...>]

Hi,

With VC6 there is a problem of non supplied arguments.
Like in this:

WX_DEFINE_SORTED_USER_EXPORTED_ARRAY(wxLuaDebugDataItem *, 
wxLuaDebugDataItemArray, WXDLLIMPEXP_WXLUADEBUG );

Here it is only a warning.

Or in my case:

wxLUA_DECLARE_ENCAPSULATION(    ,     MaskprocLuaWrapper)

This gave an error, but for some reason this works:

#define WXDLLIMPEXP_WXARTBIND
wxLUA_DECLARE_ENCAPSULATION( WXDLLIMPEXP_WXARTBIND,MaskprocLuaWrapper)

So not really an issue, when using the above trick, but why it works??

Klaas.

[Wxlua-users] binding problem

[k. h. <kla...@nl...>]

Hi John,

I have this in my rules.lua file:

-------------------------------------------------------------------------------
-- Set any #includes or other C++ code to be placed verbatim at the top of
--   every generated cpp file or "" for none
hook_cpp_binding_includes = "#include \"general/include/a2dprec.h\"\n"

As it says it should be "at the top".
And in my luabind.i I have this at the top:

%include "general/include/a2dprec.h"

%include "docview/include/doccom.h"
%include "docview/include/cparser.h"
%include "artbase/include/drawer2d.h"
%include "luawraps/include/luawrap.h"

But in the bindings generated, a2dprec.h as not at the top anymore.

e.g. i get in wxart2d_bind.cpp the following order at the top:

#include "wxlua/include/wxlstate.h"
#include "luawraps/include/luabind.h"
#include "general/include/a2dprec.h"
------------------
And in luabind.h i get this ( lower in file order of include files is 
different plus a2dprec.h not at the top. ):

// 
----------------------------------------------------------------------------
// wxart2d.h - headers and tags for wxLua binding
//
// This file was generated by genwxbind.lua
// Any changes made to this file may be lost when file is regenerated
// 
----------------------------------------------------------------------------

#ifndef __HOOK_WXLUA_wxart2d_H__
#define __HOOK_WXLUA_wxart2d_H__

#include "wxlua/include/internal.h"

#include "wxbind/include/wxbind.h"

// binding class
class wxLuaBinding_wxart2d : public wxLuaBinding
{
public:
    wxLuaBinding_wxart2d();
    virtual wxLuaBinding* Clone() const { return new wxLuaBinding_wxart2d; }

protected:
    virtual void PreRegister(const wxLuaState& wxlState, bool 
registerTypes, int luaTable);
    virtual void PostRegister(const wxLuaState& wxlState, bool 
registerTypes, int luaTable);

    DECLARE_DYNAMIC_CLASS(wxLuaBinding_wxart2d)
};

// bind wxLuaBinding_wxart2d to a single wxLuaState
extern  bool wxLuaBinding_wxart2d_bind(const wxLuaState& wxlState);
// initialize wxLuaBinding_wxart2d for all wxLuaStates
extern  bool wxLuaBinding_wxart2d_init();

#include "artbase/include/drawer2d.h"
#include "docview/include/cparser.h"
#include "docview/include/doccom.h"
#include "general/include/a2dprec.h"
#include "luawraps/include/luawrap.h"

---------------------
Same in luabind.cpp:

// 
----------------------------------------------------------------------------
// This file was generated by genwxbind.lua
//
// Any changes made to this file may be lost when file is regenerated.
// 
----------------------------------------------------------------------------

#ifdef __BORLANDC__
    #pragma hdrstop
#endif

#ifndef WX_PRECOMP
     #include "wx/wx.h"
#endif

#include "wxlua/include/wxlstate.h"
#include "luawraps/include/luabind.h"
#include "general/include/a2dprec.h"


This gives me problems to compile it, the #include 
"general/include/a2dprec.h" for precompiled headers must be at the top.
And of course it also important that the order of include files stays 
the same as defined in the luabind.i.

It was oke some time ago, can you change this to be like before?

Thanks,

Klaas

[Wxlua-users] lua5.1.exe

[k. h. <kla...@nl...>]

Hi,

I see that in the bin directory there is now lua5.1.exe instead of lua.exe
That is on windows.
Is there a reason behind this.
I am using lua.exe to generate the bindings in wxArt2D, and the same is 
done in wxluacan in genwxbind.bat.

But somewhere else i see thise used?

SET LUA=..\bin\wxlua-lua.exe

What should is best use?
