Hi Paul,
any idea how to implement that bellow, sent earlier?

let's suppose the following minimalistic example (not tested), which is to provide GetConsoleWindow()'s (WinAPI) HWND to Lua as wxWidgets/Lua object (userdata):
---- MyLib.c
#include <lauxlib.h>
#include <lua.h>
#include <wx-something?>
int GetConsoleWindowsAsWxWindow(lua_State * L)
{ HWND wnd = GetConsoleWindow(); // WinAPI specific
wxWindow * wxw = (wxWindow *) // GetWxWindowPointerFromHWND // What to come here?
void * ud = lua_newuserdata(L, /* What to come here? */);
// Probably a metatable to be assigned to 'ud' here
return 1; // The userdata, being wxWidget actually
}
static luaL_Reg funs [] =
{ { "GetConsoleWindowsAsWxWindow", GetConsoleWindowsAsWxWindow },
{ NULL, NULL }
};
__declspec(dllexport) int luaopen_MyLib(lua_State * L)
{
lua_newtable(L);
luaL_setfuncs(L, funs, 0);
lua_setglobal(L, "MyLib");
return 0;
}

Best regards,
Lukas
