Find "a2dMaskProc" in the generated C++ code, it should be in a
wxLuaBindObject as { "a2dMaskProc", g_wxluatag_XXX, NULL, (const
void**)&a2dMaskProc }. Of course, you should be using %define_pointer
if and only if a2dMaskProc is declared in C++ as "MaskprocLuaWrapper*
a2dMaskProc;" and %define_object if this "MaskprocLuaWrapper
a2dMaskProc;".
If the above is not the problem, can you debug this code in
wxLuaBinding::DoRegisterBinding? I'm guessing the problem is in
wxluaT_pushusertag().
const wxLuaBindObject *wxlObject = m_objectArray;
for (n = 0; n < m_objectCount; ++n, ++wxlObject)
{
lua_pushstring(L, wxlObject->name);
if (wxlObject->objPtr != 0)
wxluaT_pushusertag(L, wxlObject->objPtr,
*wxlObject->wxluatype, true);
else
wxluaT_pushusertag(L, *wxlObject->pObjPtr,
*wxlObject->wxluatype, true);
lua_rawset(L, -3);
}
Hope this helps,
John
