Some changes in wxWidgets CVS head are causing more problems. They've
removed wxRED_PEN and and the rest of the objects and use a wxStockGDI
class to get them so that we get "error: non-lvalue in unary `&'" on
these objects, see wxRED_PEN below for code.
This is new wxWidgets code
#define wxRED_PEN wxStockGDI::GetPen(RED_PEN);
static wxPen* wxStockGDI::GetPen(int type);
=========================
My question is why do we have objPtr and pObjPtr in WXLUAMETHOD? When
would pObjPtr be needed instead of just assigning the pointer value as
is to objPtr? The fix to the above is not terrible, a little annoying,
but I guess I'd like to understand this first and remove pObjPtr is
it's not needed.
Thanks,

=========================
wxlua/include/wxlbind.h
struct WXLUAOBJECT // Defines a wxWidgets object or
pointer for wxLua
{
const void *objPtr; // a pointer to the object or pointer
const void **pObjPtr; // a pointer to the object or pointer
const char *objName; // the name of the object or pointer
int *objClassTag; // the class tag of the object or pointer.
};
=========================
is used, for example, in in wxbind/src/wx_bind.cpp for
wxWidgets has (or used to for wxRED_PEN) these
wxPen wxNullPen; (an object)
wxPen* wxRED_PEN = new wxPen(...); a pointer
{ &wxNullPen, 0, "wxNullPen", &s_wxluatag_wxPen },
*** error on next line
{ 0, (const void **) &wxRED_PEN, "wxRED_PEN", &s_wxluatag_wxPen },
=========================
and wxlua/src/wxlbind.cpp
// install the objects and pointers
for (size_t iObject = 0; iObject < m_objectCount; ++iObject)
{
WXLUAOBJECT *pObject = m_objectList + iObject;
lua_pushstring(L, pObject->objName);
if (pObject->objPtr != 0)
wxlState.tpushusertag(pObject->objPtr, *pObject->objClassTag);
else
wxlState.tpushusertag(*pObject->pObjPtr, *pObject->objClassTag);
lua_rawset(L, tableOffset);
}
