Great. I found that and it built!

Too bad. This is awesome!!!! I can't believe I will be able to script
our test software.

Really the documentation was good at describing the functionality, but
these emails with the "How-To" style and always an example are great.
I guess what I am saying is see if you can give the general
step-by-step for all the steps from start to finish. Plus I would not
have known that wxLua had such a great framework for creating
bindings. You should advertise this on your website. Along with in the
documentation. It is really good.
Also I don't know if you want to get into Lua internals on your
website, but I still have know idea what the "wxlstate" is and its
makeup, so some tutorials on interfacing C++ code and Lua would be
greatly appreciated. If there are great links to already existing
articles, maybe that could be all that tutorial shows. I have been to
the Lua site and I think there documentation is written as a
specification and I would love a more tutorial articles on the
interface.
OK another question. How do I call a function like this:
Open() is the function I am wrapping and here is its documentation.
/*!
\param devname name of the interface, we want to open
\param dcs a untyped pointer to a device control struct. If
he is NULL, the default device parameter will be used.
\return the new file descriptor, or -1 if an error occurred
The pointer dcs will be used for special device dependent
settings. Because this is very specific, the struct or
destination of the pointer will be defined by every device
itself. (For example: a serial device class should refer
things like parity, word length and count of stop bits,
a IEEE class adress and EOS character).
*/
Interface file:
%class %delete %noclassinfo %encapsulate wxSerialPort, wxSerialPort_x
wxSerialPort()
// Serial port initilization
...
int Open(const char* devname, void* dcs)
...
%endclass
Generated function:
static int LUACALL wxLua_wxSerialPort_Open(lua_State *L)
{
wxLuaState wxlState(L);
int returns;
// void dcs
void * dcs = (void *)wxlState.ttouserdata(3);
// const char devname
const char * devname = (const char *)wxlState.ttouserdata(2);
// get this
wxSerialPort * self = (wxSerialPort *)wxlState.GetUserDataType(1,
s_wxluatag_wxSerialPort);
// call Open
returns = self->Open(devname, dcs);
// push the result number
lua_pushnumber(L, returns);
return 1;
}
Using it in wxLua:
-- device control struct for additional (and device specific
-- settings)
dcs = wxctb.wxSerialPort_DCS()
-- dcs was initiate with 19200 1N8, but you can change
-- these with your own settings
dcs:SetBaud( baudrate )
dcs:SetWordLen( 8 )
dcs:SetParity( wxctb.wxPARITY_NONE )
dcs:SetStopBits( 1 )
-- Create the wxSerialPort variable.
com = wxctb.wxSerialPort()
-- try to open the given comport
if ( com:Open( devname, dcs ) < 0 ) then -- <- this call fails everytime
-- port is not available (wrong or in use)
print( "An error occured when opening serial port \""..devname.."\"" )
return 1
end
It keeps failing. I can call other functions that I have wrapped, but
the reference to a class doesn't seem to work well for me,
