[Wxlua-users] Borland builds

[Francesco M. <f18...@ya...>]

Hi,
    I've found that there are only two small problems with wxLua builds 
with BCC: I've already solved one.

The next is something which I tried but failed to fix: on some 
autogenerated binding files, e.g. modules/wxbind/src/file.cpp, line 2002 
there are ?: operators in form:

wxString filespec = (argCount >= 3 ? lua2wx(wxlState.GetStringType(3)) : 
wxT(""))

unfortunately borland gives an error for this saying that both returned 
variables of ?: operator must be of the same type.
I.e. it doesn't like that wxT(""). Changing it to wxString(wxT("")) or 
to wxString(wxEmptyString) fixes the problem (not changing it to 
wxEmptyString, though).

I've tried to scan all code of the wrapper and I've found that at line 
3297 of genwxbind.lua there is:

table.insert(codeList, "    "..declare.." "..argName.." = (argCount >= 
"..argNum.." ? "..argItem.." : "..opt..");\n")

however putting a

if opt=="wxT(\"\")" then
	opt = "wxString(wxEmptyString)"
end

just before it does not produce any change. In fact I've hacked it a 
little more and I believe that the problem is not there as that lines 
correctly generates the wxString(wxEmptyString) code.

Anyone which is more experienced with genwxbind.lua knows if there is 
something like a filter for replacing wxString(wxEmptyString) -> wxT("") ?

Thanks,
Francesco
